Computer problems

  • Meeeedia Server, why do you hurt me so?

    Bdr-bdr-bDRRRRR-bdr-bdr-drrrr-drrr-bdr-bdr-drrrr-drrr-bdr-bdr-drrrr-drrr-bDRRRRR….

    I’ve been sat here on and off through the day tweaking the server. I’m not sure why it’s randomly, occasionally rebooting. Seems to happen only under heavy loads, but weirdly more under heavy graphical loads than anything else, and it’s not like it’s a really umphy graphics card.

    One day I'll have a fully installed media server... It may not be today.

    Nothing in the logs, because it literally seems to be a DROP EVERYTHING NOW reboot. No errors recorded, just ‘la la la REBOOT la la la”. I’m trying to be a bit more gentle with it, I was asking it to simultanously scan the audio directory into Logitech Media Server and the film directory into Plex. This may have been a trifle harsh.

    I’m slightly wondering if the powersupply is flaking out, it’s meant to be 700 watts, according to its packaging, but it wasn’t exactly a pricey supply.

    Anyhow, it’s chugging along. I’d like to get it scanning the TV Series rips, but Plex’s having a complete hissy fit about that, refusing to even acknowledge that there are files on the drive. I’m hoping it’s a bug that’ll be gone when I upgrade it. Which I’d do…except it’s in the middle of scanning the audio directory. Which may take the rest of my life. Despite the 4 cores and 6 Gig of memory. Irritatingly, unlike LMS which does a quick scan of the number of files, then gives you a percentage, Plex (at least this version) seems to just give you the current file it’s scanning. Which is fine for ‘normal’ people who don’t ridiculous music libraries that have terrabyte drives all to themselves. Every so often it pauses and I think it’s done.

    But then…

    Bdr-bdr-bDRRRRR-bdr-bdr-drrrr-drrr-bdr-bdr-drrrr-drrr-bdr-bdr-drrrr-drrr-bDRRRRR….

    All I can do is hope that I work out why it’s rebooting randomly occasionally. Because that’s not the kind of behaviour I want to encourage.

  • An ‘unfortunate’ quirk

    So having installed the much updated Ubuntu 14.04 I’ve run into an interesting bug. Using the graphical filer window to copy large amounts of data (by which I mean, the smallest amount I was copying when the bug appeared was around 20Gig – or the amount of data I generated doing Dead Bug Jumping (which I really hope to get back to at some point))…

    It’ll be copying and copying and then *FZT* the machine reboots. No warning, no errors generated. Just suddenly reboots.

    I’ve no idea why.

    I’ve even less idea why because if I stick ‘cp -r ….’ on the command line it’ll happily do the job.

    Other than that I’ve done a lot of data shuffling, and I’m thinking we’re most of the way towards an install. I just wish I knew what this rebooting nonsense was about.

  • Failure is a dish best served…err…on rapidly spinning platters?

    I failed to check one teensy tiny thing. The old install was still running as 32 bit. Because, well, the processor it ran on, with its single core, was a 32 bit processor.

    The new one? 64 bit. Should be running a 64 bit OS.

    Also, Ubuntu doesn’t seem to like the upgrade very much. It’s working, but there’s random errors, and various bits seem to have failed.

    …so tomorrow I’ll be upgrading the upgrade. Well, nuking the site from orbit (it’s the only way to be sure). On the plus side, it means I can yank the 1Tb drive that’s just sitting there at the bottom of the case.

  • Upgrade day!

    So, the poor old media server today finally got disassembled. After many years of service a new 4TB disk arrived today which prompted the gutting and rebuilding of the old computer…

  • ’tis the season for stupidity

    I spent quite a while trying to work out what was up with Logitech Media Server trying to work out why it wasn’t adding the files…

    …and then I realised all the permissions were wrong. LMS didn’t have access to read the files. Which explains why it didn’t add them.

    I am, it turns out, a moron.

  • In addition

    So yesterday, whilst I was dinking with the media server I found the missing rips! Because I’d not known which disks were missing (I could have fished out the CD Boxes and worked out which disk I’d got up to then worked backwards to find them, I suppose, but that’s a bit much like effort) I’d not had anything specific to look for.

    It turns out that I’d created (at least) two separate FLAC folders, one which is where I thought it should be, and another which is in the ‘dump files for the server’ here folder (which to tie in with the Mac is called ‘DropBox’). I think that dates back to a time when I had so many problems with read/write access on the server from MacOS that I just created one folder that I could fight with rather than many.

    Despite being half asleep I worked my way through putting cover art in the ones that were missing it, I then spent an enjoyable chunk of time merging the folders making sure that there were no duplicates. I now have a ‘clean rips’ folder and a ‘digital downloads’ folder that actually make sense. Of course, the old ‘MP3’ folder’s a flipping disaster area and still contains a lot of digital downloads from the pre-FLAC era.

    However, the repaired Squeezebox has been providing good service, and I looked forward today to tapping ‘New Music’ and getting lots of shiny new music (well, old music) to listen to. But for reasons that are completely inexplicable to me, Logitech Media Server’s still stuck showing some of the stuff from Christmas as ‘New Music’, and nothing since then. Given the disaster that happened last time I asked it to refresh its database I’m slightly reluctant to force an update – and given that if I ever successfully get a 4TB drive I’ll be moving the whole lot onto a shiny media server (Plex + Logitech Media Server) – I’m prepared to wait. But it is weird, they show up complete with artwork if I navigate to the directory, through the LMS interface, but it seems to just not want to scan any of the new music.

    Ah well.

    Hopefully, some of these foibles might disappear when I’ve got a somewhat more powerful server. I realised today that there seems to be an actual performance hit on the server when its streaming music to the squeezebox…which is surprising. Since it can run on a RPi. But hey, the media server’s not exactly high spec.

  • Assembly is the reverse of disassembly, but with more cleaning

    So it’s back together. I’m leaving it another day until I turn it on for the alcohol to fully dry out…

    I ended up dremmeling the memory with a polishing wheel to attempt to get the contacts clean enough to have some hope of reasonable connections being made…

    RiscPC renovations

    You can actually see the fluff on the memory stick there (that’s the painfully expensive VRAM) – which is taken before it got another spraying with isopropyl alcohol (like the big can at the back folks? I’ve spent more on cleaning this machine than it’s actually worth)…

    RiscPC renovations

    It’s weird because when I first bought those SIMMs they were so expensive and I was insanely anxious about inserting them. Everything I read was all about how static sensitive they were. And here I am going at them with a power tool attempting to get enough corrosion off for the machine to work.

    If it does all work I might be tempted to throw RISC OS 5 or 6 into it, because then it will have exciting features like ‘DHCP’ which means it won’t be quite so much work to coax it into connecting to the internet. I need to have a look and see if they include any form of networked storage access.

    Although I’ve reassembled it, if I do get a new OS I might even find it a new disk. I had a quick meandery look around, but didn’t remember where the harddisks were living (in the drawers by the desk) until afterwards. What is bugging me is I’m fairly certain that John gave me a StrongARM 233 (as opposed to my original 200Mhz) and a 2 slot backplane (although why I want to plug in the SCSI card when I’ve no SCSI drives anymore is a good question).

    RiscPC renovations

    Still it’s all back together now, and looking at least a lot more like a computer:

    IMG_20150105_163814

    And all sat back in place ready for me to throw the switch in a couple of days.

    IMG_20150105_170416

    In other exciting computer news, the media server stuff has all arrived. Although I’m still vacillating about whether I should buy it a new hard disk.

  • It’s a weakness

    So I’ve finally given in. Nikki has been showing off the joys of Plex. I did try it before, but I think that the woeful inadequacy of the media server (Athlon 2800+ FTW) somewhat screwed that pooch. So after various thoughts of upgrading and several occasions of looking optimistically at various upgrade options I’ve given in.

    On its way is an Athlon X4 740 with associated motherboard and 6Gb of memory.

    This should be adequate for our needs, and since it says we can share our media with friends *waves at Nikki*, it should be more than adequate for that too.

    In other news, the RiscPC’s motherboard has been washed with a great deal of isopropyl alcohol, but it still looks like cack. The area directly around the battery is looking better, but a quick nose-test of the board tells me it still reaks of battery acid. That design plan which has the fan gently wafting battery acid all over the rest of the board has really done a bit of a number on it. I’m pondering washing it with a gallon of distilled water; but the issue then is drying it. We haven’t got an airing cupboard to dry it in…so I’m a bit unsure about how to ensure it dries rapidly and without turning into a pile of oxidisation.

    The other option is to go and buy a lot more isopropyl alcohol…

    I’m also pondering whether to stick a new hard disk in. The original one in there is now about 20 years old, which is probably pushing it in hard disk terms, really. Of course, when I say ‘new’ what I really mean is ‘less old’. Since the biggest drive it can support is 128Gb, which would be beyond overkill for a machine I barely use, and this being entirely a ‘fix it before it breaks, copy the data off the old drive onto the new one’ process I’m inclined to find one of my ‘spare’ drives. Of course, then comes the joy of trying to find a spare ATA drive… I’m sure I have some, somewhere. But where is going to be an interesting question.

  • It looked so innocent

    So Kathryn gave me some CDs for Christmas. One was St. Vincent, the other Elizabeth Cotten. Being as I’m trying to be better about these things; and also because I fancied listening to Elizabeth Cotten over dinner, I ripped it and plonked it over on the media server.

    Unfortunately, it did not deign to quite work as desired, and as occasionally happens the kitchen media player fell off the network (I think it needs a more powerful power supply) and refused to reconnect. So we ended up listening to it on my laptop…

    Today I ripped the St. Vincent album and despite, or perhaps because of my general malaise around doing anything today (the whole day has slid by without me achieving anything much) I suddenly took it upon myself to sort out the clean rips on the media server. I sat and manually sorted through each folder checking the names, that the format was correct, that the folder names were organised the way I wanted, then I shuffled the ‘clean’ ones over to a new folder.

    Then I did it. The button looked so innocent, and I’ve pressed it so many times in the past.

    logitech

    And Logitech Media Server disappeared. It runs as a service on linux and checking the services list revealed:

    [ ? ] logitechmediaserver

    After an XKCD worthy hour I finally managed to get it uninstalled, removed it’s special login, the preference files apt refused to remove and got it reinstalled. It still seems to be doing some slightly odd things, but I’m putting that down to the fact it’s still scanning ‘rather a lot’ of music files.

    And now I’ll get back to reading my magazine, which was the plan before it all started.

  • The Massive Ripping Project

    It has been, it must be said, a total failure. Why? Because I’m lazy. And added to that problem I love music, and film, and so there are an enormous, and continuously growing number of disks. DVDs, Blu-Rays, CDs; they keep arriving (at least sporadically), to say nothing of the Vinyl and the odd digital download.

    The media horde is massive and unmanagable at present and despite my best intentions, or at least my occasionally adequate intentions, I’ve not managed to get more than a few disks ripped. Not aided by the fact that the poor old MacBook is starting to show its age (I just discovered today that 4k video is out of its league. I knew that the display couldn’t actually *display* it. That’s a given, it’s only 1280×800, a teeny bit short of the 3840×2160 that my OnePlus One will throw out as video. But I thought – as I often do – shoot in the best quality you can handle.

    Turns out I can’t handle that.

    Pity.)

    Anyhow, so the great ripping project… Well first there was the issue of the randomly empty folders. Then there was the issue of the sometimes missing artwork. Then there was… get the idea? It all did not go well. On top of which there was the whole thing of: oh hey, Kate’s got to sit and enter all the track data because her chosen ripping software will only look at one flipping database, and it’s a crap database, but it’s the only application she can find that will output both FLAC and MP3; the MP3 only being required because iTunes is a honking steaming pile of donkey droppings. I mean, my 10 year old, discontinued, unsupported Logitech music players, they support FLAC and all sorts of random file formats, but iTunes? No.

    Anyhow, rant over.

    Then, to add insult to injury, you have to pay to join the database as someone who can enter track data, so all those disks I added, if I rip them again, I’ll have to re-enter that track-frigging-data. It has not been a rewarding experience.

    But then, thanks to the joy of illness, I discovered this:

    It is a 3D printable CD/DVD/Blu-Ray robot ripper. Give it a stack of CDs and off it goes. Now it doesn’t overcome some of the problems (namely the cover art / track name problems for the more eclectic bits of our collection); and it requires another Raspberry Pi to drive it… and a servo controller for the pi… but I’m pretty enthusiastic about it. Assuming our roof, when replaced, does not completely consume all of our money.

    And it may overcome the tracknames / artwork problem because now, as I have a shiny new phone that is not my craptastic iphone 4 I don’t have to bother with keeping iTunes around as a main source of media management. (I’d be happier if DoubleTwist would talk MTP to the phone and if I could share podcasts twixt phone and Mac, because if anything makes me want to leave Apple at the moment it’s their irritating obstructiveness to anything that’s not Apple. I was aware of that when I got the MacBook, but back then the OS just worked, or at least, it did for me. These days it doesn’t seem to be that much more reliable than any other OS, and it’s taking more and more effort to keep it working… and because it’s pretty opaque about the way it does things (being as it’s meant to just work) it can be difficult to fathom what’s broken… and I daren’t let them install the shiny newest OS on my MacBook since their last OS update made my phone into a heap of junk, and every OS update has made my poor MacBook slower).

    Anyhow, so that’s something for me to acquire the parts to build and get 3D printed…) and that’s also all my news.

    Also, after 5 days of not being able to concentrate on reading long enough to manage more than a few sentences, I’m back sat upright, I even went outside willingly today (for a short walk – during which I decided rather rapidly that I’m really not nearly as well as I’d like to be). So, yay.
