Ok ran check then repair output doesn't look to good ? Here is last lines of process.. Metadata corruption detected at 0x44d778, xfs_bmbt block 0xec37d798/0x1000 libxfs_bwrite: write verifier failed on xfs_bmbt bno 0xec37d798/0x1000 Maximum metadata LSN (2146145896:-2144772351) is ahead of log (22:71999). Format log to cycle 2146145899. xfs_repair: Releasing dirty buffer to free list! cache_purge: shake on cache 0x5021c0 left 3 nodes!? xfs_repair: Refusing to write a corrupt buffer to the data device! xfs_repair: Lost a write to the data device! fatal error -- File system metadata writeout failed, err=117. Re-run xfs_repair. Options ? above run in mainteance mode only way to activate check option I do have another disk available to try as a replacement for SDC ? Original SDC is still available but jammed in drive cage

just struck a problem with fixing above had a delay due to a damaged cage drive so had to switch hardware. Have inserted new disk 1 and did a rebuild. When reboot 2 things are happening; 1. it is saying disk 1 ''Unmountable disk present: '' not sure what did wrong here ? 2. All my dockers are not visible assume could be related to 1 above. updated diagnostics attached , have tried 2 rebuilds but can't work out what i have done wrong ? hptower-diagnostics-20211215-1157.zip

Thanks Trurl , will wait to current parity option finishes, about an hour then follow the steps you have outlined. Assume once data disk 1 is rebuilt and all boots ok can go ahead again and replace the parity disk ? then start gradual upgrade of each data disk. Really appreciate your help and advice.

ok , so I have a replacement ready brand new but is same size as original parity 8tb is that ok ? or an older 4tb drive which one to use? So what steps do I follow , assume let parity rebuild follow first

Thanks for your help to answer questions; No notification about disk 1, Yes it has a notification on dashboard now about error, No wasn't reason decided to replace parity I need to expand array as running out of disk so replacing parity first. No nothing written to array since rebuild started, yes still have original parity disk, yes copies of most of important data etc , just my movie collection on there that is not backed up. Options ?

Hoping for some direction on error encountered. Array running out of space so started process to replace Parity Disk with a larger one, all going ok till struck an error in rebuild it is a read error of of one of the disks see below. Current rebuild has got another 3 hours to go to finish. Prior to parity upgrade was no errors and last parity rebuild was all good. Question , Is this something to worry about and will it lead to some data loss ? When it finishes if reboot will the error correct itself ? I have new data disks to install and old parity disk still available. Any help or suggestions appreciated Thanks in advance Justintas Parity - ST12000VN0008-2PH103_ZS802V5R (sdb) - active 33 C [DISK INVALID] (new parity Disk getting rebuilt) Disk 1 - WDC_WD40EFRX-68N32N0_WD-WCC7K2PF6VZX (sdc) - active 31 C (disk has read errors) [NOK] Disk 2 - WDC_WD40EFRX-68N32N0_WD-WCC7K3EN931N (sdd) - active 31 C [OK] Disk 3 - WDC_WD40EFRX-68N32N0_WD-WCC7K5FREU23 (sde) - active 31 C [OK] Parity sync / Data rebuild in progress.
