December 4, 20169 yr Hello, My SDD cache disk is reporting some smart errors so I'd like to replace it with a new larger one. I'm using the cache disk for docker and the docker configuration. What is the best way to swap the cache disk? Although downtime isn't a problem, I'd prefer to not have to rebuild all of the docker set up so if I create a cache pool with both SDDs included and set it as mirrored and then remove the old SDD once the process is done I think I'll get everything copied. But how do I increase the size of the remaining SDD to reflect it's larger capacity. And as I think about it how do I revert the cache to a single disk without losing it's data (I don't want to be endlessly bugged about the missing old disk). Thanks in advance, Alan.
December 4, 20169 yr Community Expert Add the new device to the pool (if the current one is BTFRS) then use this procedure to remove the old cache disk: http://lime-technology.com/forum/index.php?topic=48508.msg484479#msg484479 Cache size will be automatically expanded to reflect the new device.
