June 28, 20224 yr I am seeing a lot of these errors in Tools/Syslog ata3.00: failed command: READ FPDMA QUEUED ata3.00: exception Emask 0x10 SAct 0x3ff8 SErr 0x4090000 action 0xe frozen I assume I have one or more bad disks -OR- bad SATA cables, or worse yet a bad mobo. Can someone tell me which drive to focus on? If I am totally wrong, can someone point me to what the culprit is? wideglide-diagnostics-20220628-1126.zip Edited June 28, 20224 yr by PapaThiele Grammer
June 28, 20224 yr Community Expert This is usually a power/connection issue, and since it's affecting 4 disks connected to the motherboard, disks 7, 8, 9 and 10, see if they have something in common, like a power splitter, could also be a board issue but it's not very likely, also the other two disks connect to the same controller don't show any issues.
June 29, 20224 yr Author I tried reseating the power & SATA cables but now all I get for Disk 7 is "Unmountable disk present: Disk 7 • WDC_WD80EMAZ-00WJTA0_2SG6B9AJ (sds)" wideglide-diagnostics-20220628-1942.zip
June 29, 20224 yr Community Expert Parity is rebuilding, disk7 is unmountable. Is that correct? Didn't notice any I/O problems in latest diagnostics. Check filesystem on disk7
June 29, 20224 yr Author Parity is rebuilding, disk7 is unmountable. Is that correct? I get nervous with this...is this correct? "xfs_repair -v /dev/md7"
June 29, 20224 yr Community Expert Simpler to do it from the webUI, it knows what is correct. I should have linked this instead. https://wiki.unraid.net/Manual/Storage_Management#Running_the_Test_using_the_webGui
June 29, 20224 yr Author Phase 1 - find and verify superblock... Phase 2 - using internal log - zero log... ALERT: The filesystem has valuable metadata changes in a log which is being ignored because the -n option was used. Expect spurious inconsistencies which may be resolved by first mounting the filesystem to replay the log. - scan filesystem freespace and inode maps... - found root inode chunk Phase 3 - for each AG... - scan (but don't clear) agi unlinked lists... - process known inodes and perform inode discovery... - agno = 0 - agno = 1 - agno = 2 - agno = 3 - agno = 4 - agno = 5 - agno = 6 - agno = 7 - process newly discovered inodes... Phase 4 - check for duplicate blocks... - setting up duplicate extent list... - check for inodes claiming duplicate blocks... - agno = 0 - agno = 5 - agno = 1 - agno = 3 - agno = 4 - agno = 7 - agno = 6 - agno = 2 No modify flag set, skipping phase 5 Phase 6 - check inode connectivity... - traversing filesystem ... - traversal finished ... - moving disconnected inodes to lost+found ... Phase 7 - verify link counts... Maximum metadata LSN (1:2822794) is ahead of log (1:2820534). Would format log to cycle 4. No modify flag set, skipping filesystem flush and exiting.
June 29, 20224 yr Community Expert Solution Run without the -n option (and if it asks for it add the -L option). After that you should be able to restart the array in normal mode and I would expect all the data to be intact.
June 29, 20224 yr Author Awesome, it worked! All my data appears to be there...from Golden Girls to ummm, never mind. I really appreciate the help.
June 29, 20224 yr Author Dangit! It went back to: "Unmountable disk present: Disk 7 • WDC_WD80EMAZ-00WJTA0_2SG6B9AJ (sds)" Befotre thiss happened I notice a s#!t-ton of errors being written while the parity was rebuilding. I have another disk pre-clearing. I'll let that finish then replace #7, or at least let it run for now. It's late & I'm too tired to try anything but if anyon leaves unstructions, I'll run through them in the mornin. wideglide-diagnostics-20220628-2310.zip
June 30, 20224 yr Author I removed everything from my case, replaced any splitters & made sure everything was secure. Seems to have done the trick.
June 30, 20224 yr Community Expert How much data is in your lost+found share after the filesystem repair?
