I thought the data in a RAID 1 cache pool was mirrored?

It is but like mentioned your pool was out of sync due to dropping devices, see here for better pool monitoring so you can take immediate action if it happens again.

Just hijacking this briefly. I have a 2 SSD cache which i want to change to a single ssd- i've run the convert to single mode command which went fine.

 

Then stoppped the array and unassigned the second drive from the cache, restarted the array but now it's saying unmountable:no file system

i have a backup so I'm not too stressed but wanted to know if this can be fixed and if not, what did I do wrong?

 

TIA

You cannot remove a drive from a pool using the single profile (or other non redundant profile), please post current diags after a new reboot and before array start.
