Thanks JorgeB, I'll test the cables by swapping out. Is it possible under these circumstances to rebuild onto a new disk instead of onto itself?

I restarted my UnRaid 6.9.2. system a week or two ago after months of being turned off (for non-technical reasons). It was fine for a bit but then I got "device is disabled" on disk 3. I thought it might be cables or my disk. I downloaded diagnostics, powered down, checked cables (they seem OK) then powered up again. It's still disabled. I reran diagnostics. As far as I can tell the SMART data is OK. Diagnostics from before and after power down are attached. What do I do to get disk3 out of its disabled state? I have a new disk ready to go if it's needed - in fact if appropriate I'd rather rebuild onto the new disk - I need to add some extra space to my array anyway, and the new disk is 10Tb as opposed to disk3 which is 6Tb. Thanks as always for your help. obelisk-diagnostics-20220627-1537.zip obelisk-diagnostics-20220627-2304.zip

OK, I found a solution, although it might have been a bit clunky. I'll put it here in case it helps someone else. I'm pretty sure it was the uefi issue that got me. So to fix it I backed up my old UnRaid USB stick onto my laptop, then used the install tool to install the current version of UnRaid onto my USB, and copied my licence key back into the config folder. This meant a fresh start - I deliberately didn't attempt to copy over my old config settings. They were a bit of a mess anyway. After that I just added one of my old data drives to the array, plus a new bigger one and am currently using MC to move data from the old drive to the new. I'll repeat until I've got all my data onto my new drives (I decided to just add one at a time, rather than risk screwing up multiple drives if I stuffed something up). I'm aware I'm unprotected until I'm done and have added parity, but I can live with that.

Thanks for the quick response ChatNoir. I'm guessing I was booting in legacy BIOS. Old Mobo was ASROCK rack c2750d4i. The ASROCK product page for it doesn't mention UEFI anywhere. New mobo is ASROCK B560 Mini-ITX. My flashdrive doesn't have an EFI- folder. I'm thinking upgrading my UnRaid is probably a good idea, but I'm not sure if I should do it now or after I've solved this problem. Further guidance would be appreciated.

Hi all, after moving house a while back my Unraid 6.1.9 setup refused to boot (it didn't even post, totally dead). Some research later and it was a known fault with my mobo. So I've replaced the mobo, cpu and ram. It now posts and goes into BIOS fine, but won't boot from my Unraid USB (it boots from a new Kubuntu USB OK). The BIOS lists Unraid as the only boot option but refuses to boot from it (my data drives are currently disconnected). As far as I know nothing's changed with the contents of my Unraid USB (I hope). Can someone give me help with what to try next? Recreate Unraid on the existing USB and copy my config folder across? Start with a new USB? something else altogether? Thanks for your help.

Yes, that's fixed it! Thanks so much, johnnie.black.

Thanks Johnnie. Once I've fixed this I'll upgrade. I've found my one parity - now what? I tried assigning the unmountable disk as parity but it complains about wrong disks.

After what I suspect was a power outage I came back to my server and couldn't reach any drives. When I looked at my main page all my disks are unassigned! Dashboard is reporting SMART as OK, I don't have a record of which disk is which - what do I do next? I'm running 6.1.9, Diagnostics attached. Thanks for your help. media-diagnostics-20170924-1800.zip

Thanks turl! I recreated the docker.img and it came back before I got as far as CA. But I'll take a look at it anyway, sounds like it could be useful.

Thank you both for your responses. I have the docker tab. I'm running version 6.1.9 of unRAID. I don't have Community Apps installed (but I'll go have a look at it). docker.img and dockerconfig are back where they started (in root of disk5). Settings>Docker shows that correctly as /mnt/disk5/docker.img My docker tab says "No Docker Containers Installed". Any further ideas?

I've been moving data round and reformatting disks to xfs. Previously Plex was installed, with dockerconfig and docker.img on the root of disk5. I made sure to shut down Plex before I moved stuff, and I moved both dockerconfig and docker.img onto disk1, then back onto disk5 after I'd reformatted it. But now unraid can't find Plex and tells me I have no dockers at all. How do I fix it? And how do I make sure I clean up any mess I created (ie is there other docker info somewhere else that I have to clean up?)

OK, I managed to fix it, so I thought I'd post here in case it helps someone else (and so I can refer back if I ever need to). Turns out that disk2 has problems (and searching the forum I discovered that it's the same disk that I had problems with back in 2011!) Anyway, my new permissions weren't working because the disk was set to "read only" because of disk problems. Once I got into the console to see what was happening, after a reboot chmod would run for a bit and then suddenly stop working with "read only" errors. What I did: - copied everything I could to disk5 using cp command as root at the console - ran reiserfsck via the unraid GUI and followed its instructions - ended up with a bunch of stuff in lost+found (haven't dealt with that yet) - ran cp command again to make sure I got everything I could over to disk5 - ran chmod to change the permissions on disk5 (set them all to chmod 777, at least for now, I know it's risky but I'm the only user) - reformatted disk2 to xfs - the weird thing is the SMART data for disk2 was initially showing it had problems - after reformatting to xfs it says it's fine I thought SMART was HW only??? - I've excluded disk2 from all my shares for now until I'm sure the disk is OK - and will probably replace it, even if its smart data says it's OK I'm now moving my other data around so I can reformat all my disks to xfs. I don't know if/how much of my problems were reiser filesystem related but I'm not taking chances. Next task will be reading up on permissions and ownership and set them all sensibly - they're all over the shop at the moment, even on my other disks.

I'm running a preclear so it'll have to wait a day or so...

Thanks Frank1940, I'll give it a go. The old New Permissions haven't fixed it in the past, but doesn't hurt to try again (or rather, try this one).

I'm following along here, I've got a similar(ish) problem over at http://lime-technology.com/forum/index.php?topic=55740.0 - although my permissions aren't changing as WannabeMKII's are. And "root" is my rogue owner so deleting the user won't help ;-) I don't want to hijack this thread but if anyone can point me to the syntax for changing ownership/permissions by command line I'd be grateful!

OK, I think I found the problem - It's similar to what WannabeMKII is dealing with http://lime-technology.com/forum/index.php?topic=55718.0 although my cause must be different. When I do an ls at the command line at the console: files under /mnt/disk2 are: -rwx------ root root folders under /mnt/disk2/ are drwx--x--x root root files under /mnt/disk1 are: -rw-rw-rw- nobody users folders under /mnt/disk1 are: drwxrwxrwx nobody users So my question now is how do I change those ownderships and/or permissions? Happy to do it via command line, but my linux isn't good enough to work out the command and syntax. I'm the only user of my system so I'm happy enough to just leave everything open. thanks, Miriam

Thanks 1812, I'll take a look at that as well.

Thanks Frank, I'll look that up and use it to copy everything over to a new drive. Hopefully I won't have the same permissions error with that. It'll be way better than using a browser to move them one by one! I'll leave disk2 empty permanently unless anyone else has ideas on how I can fix the original problem.

Thanks for the responses (even if they're contradictory!) I took a look, and my options are Export (mine is yes) and Security (mine is public). Any further thoughts from anyone would be welcomed! I'm seriously thinking about emptying disk2 and keeping it empty, although moving 2TB off it via a browser is going to be more than painful. Is there some way I can get that data off more efficiently?

So I've had this problem since immediately after I upgraded from 4.7 to 5.x, and more recently to 6. Currently running 6.1.9. My disk2 had a weird permission error (all other disks are fine). I've tried running New Permissions a couple of times, and it doesn't help. If I try to access anything on that disk I get a permission error from Windows. My Plex server doesn't seem to see any files on that disk either. BUT if I go to the web interface and go to disk2/TV/whatever I can reach the files just fine (and copy them off by "downloading" via my browser). How can I fix this? I've searched the forums, as well as looked through the settings in the web interface, and also searched through the syslog for anything disk2 related but I can't find anywhere that that disk is any different to the others. Thanks for your help! media-diagnostics-20170118-1634.zip

So my box had what I suspect was a short power outage, and now disk 5 is flashing blue, and in the command area it says "stopped: upgrading disk". Parity and all my other disks are flashing green. But I haven't replaced any disks or changed any other hardware. I'm still running version 4.7. Prior to this my disk checks were all clean, and I haven't had any issues for at least 12 months. What do I need to do to get up and running again? Am I OK to just start the array and let it rebuild? thanks for your help, Miriam Edit: Oops, forgot to attach my syslog MiriamUnraidSyslog20131221.txt

I logged in this morning to prepare for adding a sata card and a couple of new drives to my Unraid - and discovered Disk3 has 0 free. Should I be worried about having lost data? If so, can I (a) work out what I've lost and (b) retrieve it? How? And do I need to do anything special before adding more disks to my array? I'm not planning to change my parity disk, just add a new Disk4 and Disk5. Thanks, Miriam Edit: whoops, forgot the syslog. and I'm running 4.5.6. media_syslog110717.zip

Hi Rajahal, Sorry, it took a while to get my kill a watt back from a friend! I get: startup: 101W (peak) booting: 75W spun up: 50W spun down: 39W checking (but not writing) parity: 82W That's with the with the 80W brick (edac EA10953A). Swapping in the 160W brick (ST-C-150-1200-1250-CT) saves me another 1-2W. Cheers, Miriam

No idea whether your board will support it, but you could look at undervolting your CPU in the BIOS. If it's supported and it'll run stable, you should be able to reduce the power consumption considerably without losing any performance.

I"m running my UnRaid server as below: X2 4000+ (undervolted to 1.0V) M2A-VM HDMI 1x2GB RAM 4x WD Green drives PicoPSU120, fanless 80W brick It was my HTPC for 3 years, until I converted it to UnRaid a couple of months back. It works just fine, I've had zero power problems. I've just bought a 160W Pico and 150W brick in preparation for adding more drives. Mind you, as Joe says, you need to be wary of how much power your mobo takes - some of them suck scary amounts. I've found silentpcreview.com to be a really good resource. Silent needs cool components which needs low power, so they look closely at power consumption of components.
