March 5, 20215 yr hello, here what i see on my unraid server. i can connect with ssh. Vm are still working and so are dockers. But i can't access any of the tools or settings. what should i do now ? when accessing syslog with terminal i see nothing as it's flooded with read and write errors there was a parity check running. 2 weeks ago i replaced a failing disk. godzilla-diagnostics-20210305-1155.zip Edited March 5, 20215 yr by caplam add diag
March 5, 20215 yr Community Expert There is no SMART information for disk3 or disk4 in the diagnostics so I suspect that they have dropped offline and a power-cycle may be required to get them back online. Might be worth waiting to see if @JorgeB has a view as the expert in these matters.
March 5, 20215 yr Community Expert Looks like a problem with the Intel SCU controller, please power/cycle the server and post new diags, after array start.
March 5, 20215 yr Community Expert Disk3 is showing a pending sector, you should run an extended SMART test, disk4 looks OK. Also need to run a filesystem check on the emulated disks 3 and 4.

ERROR: The filesystem has valuable metadata changes in a log which needs to be replayed. Mount the filesystem to replay the log, and unmount it before re-running xfs_repair. If you are unable to mount the filesystem, then use the -L option to destroy the log and attempt a repair. Note that destroying the log may cause corruption -- please attempt a mount of the filesystem before doing this. it's file system check on disk 4 how to mount it ? Edited March 5, 20215 yr by caplam

It seems like i'll loose data on disk 3 and 4.
March 5, 20215 yr Community Expert Disk4 should mount, please post new diags after array start, for disk3 on the other hand you'll likely need to use the old disk, even if it's failing.
March 5, 20215 yr Author i rebooted the server and started array in maintenance mode godzilla-diagnostics-20210305-1458.zip edit: when i stop array i have no other choice than reboot or shutdown. I can't start array. Edited March 5, 20215 yr by caplam
March 5, 20215 yr Author after a reboot and array start. Disk 3 is unmountable Disk 4 is emulated godzilla-diagnostics-20210305-1514.zip
March 5, 20215 yr Author i guess i have to resync disk 4 but how. I have no other 6Tb spare. do i have to stop array and run xfs repair on disk 3?
March 5, 20215 yr Community Expert As expected disk4 is now mounting, if contents look correct you can rebuild on top of the old disk, also try to run xfs_repair again on disk3.
March 5, 20215 yr Author rebuild is running but it's quite slow (max 90MB/S). Wouldn't it be more simple to replace disk 3 and rebuild it (of course after disk4 is rebuilt)? edit: can i run xfs_repair -n /dev/md3 while rebuild is running ? Edited March 5, 20215 yr by caplam

No, but you cancel the rebuild, run the file system check and then start over.
March 6, 20215 yr Author I let rebuild run and now disk 4 is back on line. 😀 long smart test is also finished on disk 3: smartctl 7.1 2019-12-30 r5022 [x86_64-linux-5.10.1-Unraid] (local build) Copyright (C) 2002-19, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: Western Digital Red Device Model: WDC WD40EFRX-68WT0N0 Serial Number: WD-WCC4E5CEVZTC LU WWN Device Id: 5 0014ee 20da14606 Firmware Version: 82.00A82 User Capacity: 4,000,787,030,016 bytes [4.00 TB] Sector Sizes: 512 bytes logical, 4096 bytes physical Rotation Rate: 5400 rpm Device is: In smartctl database [for details use: -P show] ATA Version is: ACS-2 (minor revision not indicated) SATA Version is: SATA 3.0, 6.0 Gb/s (current: 3.0 Gb/s) Local Time is: Sat Mar 6 17:00:13 2021 CET SMART support is: Available - device has SMART capability.

Now i will bring my array offline to try to repair disk3 filesystem.
March 6, 20215 yr Author xfs_repair -nv had been running for 2 hours now and it keeps scanning for secondary superblock. Primary one is bad i found this thread and if xfs_repair doesn't work i think i'll go with dd to clone the disk and a data recovery software such as reclaime to try to recover files.
March 7, 20215 yr Community Expert Disk3 needs to be replaced, but if the filesystem in the emulated disk can't be fixed you can use ddrescue on it and it should be able to recover almost everything.
March 7, 20215 yr Author Ok, i was thinking to ddrescue. My plan was to use it on /dev/sdq (physical disk3) to clone it on another disk. Change disk3 with a new disk and add files that could be saved. So if i understand well what you mean. I'd better use ddrescue on /dev/md3 to clone it to another disk. If files could have been saved they are at this point on a disk which is not a member of the array. I mount the disk with unassigned devices. Then replace disk3 with a new one. A parity sync will then start. At the end of the parity sync process i can add files on disk3 from the unassigned one. edit: xfs_repair didn't find any secondary superblock Edited March 7, 20215 yr by caplam
March 7, 20215 yr Author here are the things: physical disk3 is /dev/sdq emulated disk3 is /dev/md3 unassigned disk is /dev/sdj (precleared) my array is started in maintenance mode
March 7, 20215 yr Author ok so it could be that: ddrescue -f -v -r3 /dev/sdq /dev/sdj /boot/ddrescue.log if all is ok i stop array replace sdq with a new one assign it as disk3 start array in normal mode mount sdj with ud. Logically a parity sync will be triggered. With krusader i can add files from ud to /mnt/disk3

Logically a parity sync will be triggered. No, you'd need to do a new config and re-sync parity.
