Hi Guys,

After upgrading to 6.3 I received a handful of errors about not being able to read the cache drives (2 120GB drives in RAID 0). With further investigation, my entire cache directory was mounted yet could not be written to.

 

I have tried reboots,rebalances, scrubs, and even started a preclear on both drives since I have backups. The preclear cannot run because the drives are read only. Docker will not work at all because of this.

 

I know the release was recent, but has anyone seen this issue or know of a fix?

 

Diagnostics posted below.

 

Thanks!

If it's backed up easiest way would be to format it:

 

-unassign one of the cache devices

-change cache slots to 1

-click on cache and change file system to xfs

-start array, format cache

-stop array, change cache slots back to 2

-reassign other device, start array and format again.

Thank johnnie, that worked! Very thankful for backups right now...
