[zfs-discuss] How to get rid of phantom pool ?

2011-02-15 Thread Alxen4 
I had a pool on external drive.Recently the drive failed,but pool still shows 
up when run 'zpoll status'

Any attempt to remove/delete/export pool ends up with unresponsiveness(The 
system is still up/running perfectly,it's just this specific command kind of 
hangs so I have to open new ssh session)

zpool status shows state: UNAVAIL

When try zpool clear get cannot clear errors for backup: I/O error

Please help me out to get rid of this phantom pool.


Many,many thanks.

The best way to remove the pool is to reconnect the device and then
destroy the pool, but if the device is faulted or no longer available,
then you'll need a workaround.

If the external drive with the FAULTED pool remnants isn't connected to
the system, then rename the /etc/zfs/zpool.cache file and reboot the
system. The zpool.cache content will be rebuilt based on existing
devices with pool info.

Thanks,

Cindy

Remove the zfs cache file: /etc/zfs/zpool.cache.

Then reboot.
