April 10, 201412 yr Author What do you mean "parity disk shows blank"? If you are referring to the Used and Free columns that is normal. Those are meaningless for the parity drive. Could it be that the parity check that you cancelled wrote to disk1 thinking it was parity? A drive will show as unformatted if unRAID cannot mount the reiser filesystem on the drive. You say you backed up the faulty flash drive. Are there any log files in that backup that might include the period when the "disks were all messed up"? In particular we would be looking for a line like this: Apr 10 07:26:19 Tower kernel: md: import disk0: [8,64] (sde) WDC_WD40EFRX-68WT0N0_WD-WCC4E0553678 size: 3907018532 This shows that your parity drive is what we see in the screenshot. What I am wondering is whether it ever thought the drive with serial # ST3000DM001-9YN166_S1F0PQ9S was disk0. You might also consider removing all addons though I don't think they are really to blame here. You will probably have to run reiserfsck on disk 1 to get it back but I have no experience with that. Yes. two months ago Disk 1 was parity. When I booted with the old flash, unraid thought that: Parity ST3000DM001-9YN166_S1F0PQ9S Disk 1 WDC_WD20EARX-00PASB0_WD-WCAZAC998124 Disk 2 ST3000DM001-1CH166_Z1F1YREJ WDC_WD40EFRX-68WT0N0_WD-WCC4E0553678 which is now parity...showed as unassigned device in another tab. I do not see any log files for that time. And I am missing tons of files... What do i do next? As of now, unraid is shut down just in case.
April 11, 201412 yr Author Have the SATA cables been replaced? Yes. I replaced the cables. I also have hot swap enclosure and I moved disk 1 and two to two different bays...just in case, but still disk 1 unformatted and I am missing a lot of files. I think disk 1 was written a little as parity..... What should I do?
April 11, 201412 yr Author Cmon guys, somebody help me I ran reiserfs on disk1 and got: Failed to open the filesystem If the partition table has not been changed, and the partition is valid and it really contains a reiserfs partition, then the superblock is corrupted and you need to run this utility with --rebuild-sb. Should I pull out disk1 and run parity?? I am afraid that there is something wrong with the parity disk as well because I am missing a lot....more than half of my files when unraid is on. Please I need to have unraid working again.
April 11, 201412 yr Author I ran reiserfs on disk1 and got:What EXACTLY did you type? i typed this reiserfsck --check /dev/md1
April 11, 201412 yr It appears that in trying to diagnose the problem in the subject line he booted up an old flash drive with a different disk configuration than his current one. This caused unRAID to start a correcting parity check on a data disk that was formerly a parity disk. Now he needs help recovering that data disk. I don't know if that disk can have its reiser partition restored. Or maybe it can just be rebuilt from parity. It sounds as if the array is not able to similate the missing disk though. I don't know the best course of action. Hopefully one of the experts will step up with better diagnostics and suggestions. P.S. I guess this is a scenario that wasn't considered in the debate about whether the array should default to correcting parity after an unclean shutdown.
April 11, 201412 yr If you still aren't getting any help: The subject of this topic sounds like a networking problem, but now you have a possible data loss problem. You might get more attention if you start a new topic about your possible data loss and link back to this topic for context.
