The last few weeks my Unraid 6.2 install has been very unstable.

I had to replace one disk because sync would fail saying the drive was marked as read only.

I did a preclear the new disk checked out of so i rebuilt the array with it.

Everything was ok for a day or to until this morning when the system hung.

 

I rebooted the system and now the web interface will not load if i have the new drive attached ( a message about no file system in the syslog)

If i remove the new drive the server will boot,  but it will not mount the disks.

The system just hangs when trying to mount the disks. 

 

Attached is the syslog  that was run 10 or so minutes into being hung on mounting disks.

syslog10.txt

Looks like there may well be file system corruption on disk 6.

 

To check for this you want to start the array in Maintenance mode, and then click on disks 6 to run the xfs_repair tool.  If that indicates there IS corruption then you will need to remove the -n option to run it in repair mode.  When prompted to do so you may be told you also need the -L option, and if so use that as well.

 

If you have the array set to auto-start then you can disable this by manually editing the disk.cfg file in the config folder on the flash drive and changing the autostart option from "yes" to "no"
