#Freenas volume manager set up zfs pool full
Start by making sure you have a full and tested backup of your pool. The key is that this MUST be done one disk at a time. But ZFS is more efficient about resilvering than traditional RAID is, so depending on how full your pool is, it might not be so bad. It's relatively painless, although it will entail several iterations of resilvering the pool onto each new drive, one at a time. So instead of adding more drives, you can switch to larger drives. You won't be able to remove the mirror vdev from the pool, except by creating a new pool, copying the data from the old pool to the new pool, and then destroying the old pool.īut you can certainly expand the capacity of your current pool, so long as you don't change its vdev structure. You have a somewhat unusual configuration of a raidz1 vdev concatenated with a mirror vdev. zpool remove does support removal of concatenated disks or concatenated mirrors. For readers who encounter this issue in more recent times, as of this writing, zpool remove does not support removing VDEVs from a pool that contains one or more raidz VDEVs. Especially given the time of your post, ZFS does not support removal of VDEVs from a pool. Given your configuration, you will not be able to remove the mirrored drives without creating a new pool and copying to it. Copying the data to a temporary holding spot.drives to RaidZ1 andĬompletely remove the mirrored drives.
