August 21, 20223 yr I upgraded from 6.9.2 to 6.10.3 just this afternoon. The server was working okay for about 6 hours, but then my 18TB disk has dropped offline twice in different ways - first it went to unassigned devices and clicking the disk log showed the following error messages: Aug 21 16:37:24 Tower wsdd2[7429]: starting. Aug 21 23:06:16 Tower kernel: sd 4:0:0:0: [sdd] Synchronizing SCSI cache Aug 21 23:06:16 Tower kernel: sd 4:0:0:0: [sdd] Synchronize Cache(10) failed: Result: hostbyte=0x04 driverbyte=DRIVER_OK Aug 21 23:06:16 Tower kernel: sd 4:0:0:0: [sdd] Stopping disk Aug 21 23:06:16 Tower kernel: sd 4:0:0:0: [sdd] Start/Stop Unit failed: Result: hostbyte=0x04 driverbyte=DRIVER_OK Aug 21 23:07:21 Tower emhttpd: error: hotplug_devices, 1719: No such file or directory (2): Error: tagged device WDC_WD180EDGZ-11B2DA0_2JGPE3MG was (sdd) is now (sdg) Aug 21 23:45:55 Tower kernel: XFS (sdd1): log I/O error -5 Aug 21 23:45:55 Tower kernel: XFS (sdd1): Log I/O Error (0x2) detected at xlog_ioend_work+0x50/0x6e [xfs] (fs/xfs/xfs_log.c:1377). Shutting down filesystem. Aug 21 23:45:55 Tower kernel: XFS (sdd1): Please unmount the filesystem and rectify the problem(s) I took diagnostics which are attached to this post. I googled and found a link to the forum that suggested to reboot the server, which I've done and it came back online okay. In the next 10 minutes after startup, it dropped off again and now shows under 'historical devices'. I took more diagnostics which are attached too. The drive still appears in the cache pool area (it's its own pool) but when I click to view its contents, rather than listing my folders it looks like it lists a linux filesystem, per the attached image. Thought this was very odd. I hope I don't have to rollback - even if that's a thing. Any help would be appreciated, thank you.

August 21, 20223 yr Author So I have rebooted again and run xfs-repair. It seems to be running okay for now so I will monitor the disk.
September 15, 20223 yr This happened to me today, also running 6.10.3. I'll reboot my server and see if it come back online again.
