I replaced my cache drives a month ago. Everything was fine. Today we had a power outage, so I had to shut the server down. It's on battery backup, so no big deal. Bringing it back up this evening, the array didn't autostart and the cache drives are saying they're wrong and being emulated (when the array is started). It's showing the serials for the OLD cache drives as missing and showing the new cache drives as the selected, but wrong drives. Starting the array, as mentioned, says it's being emulated. But these drives have been in use for a month without this issue. What do I do?

 

Thanks!

Stop array, unassign all pool devices, start array, stop array, re-assign all pool devices, start array.

I guess that's what I did, in effect. Though your way would have been simpler.

I did a new config and just assigned all the disks back to the same positions. Seems to have worked, though the parity had to be re-synced with this method.

 

Thanks!
