Hi, I can't drop a zpool that have a removed disk:
root@isuvir14:/root # zpool status backup
pool: backup
state: SUSPENDED
status: One or more devices are faulted in response to IO failures.
action: Make sure the affected devices are connected, then run 'zpool clear'.
see: http://www.sun.com/msg/ZFS-8000-HC
scan: resilvered 6.86G in 0h0m with 0 errors on Mon Jun 27 12:32:00 2016
config:
NAME STATE READ WRITE CKSUM
backup SUSPENDED 0 0 0 experienced I/O failures
emcpower0a UNAVAIL 0 0 0 cannot open
root@isuvir14:/root # zpool export backup
cannot export 'backup': pool I/O is currently suspended
root@isuvir14:/root # zpool export -F backup
cannot export 'backup': pool I/O is currently suspended
root@isuvir14:/root # zpool clear backup
cannot clear errors for backup: I/O error
Any suggestion?
