November 24, 20223 yr 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.
