Unable to remove cache drive from pool

Featured Replies

I stopped array, unassigned drive and restarted array.  Waited for operations to finish then stopped array again, changed slots to 2 and couldn't start the array saying invalid expansion.  I had to do a new disk config to get the array started with just the 2 cache drives again.

7.0.0-beta currently doesn't support removing pool devices, only disabling them, it will show a red x, this functionality should hopefully be restored before stable is out.

In the current state is there any risk to downgrade?

Should be OK if it's not a beta formatted zfs pool, since that won't mount, but you may need to re-import the pool to remove the missing device.

Then it's fine, but you may need to re-import the pool.

Everything worked out with the pool after downgrading to 6.12.11.  But array will no longer start on boot even though setting is yes.  Even after upgrading back to 7.0.0-beta2 as I need Arc support.  Would this be because I broke parity and it needs to be redone?

Seems unlikely, try reaplying the setting, is there any warning on the bottom of main after boot?
