Replaced drive tried to rebuild no success with only some zfs related commands causing lock. After adding another drive and attemping to add it to current pool so i could try the zpool offline method, now all zpool related commands lock up and can't be ctrl-c or kill 9 or anything. Pool is uncontrollable now and i assume only way around is too recreate everything from scratch. [update] Even this isnt possible as zpool destroy tank also freezes some command results: [root@johan ~]# zpool status I do a CTRL-T load: 0.00 cmd: zpool 1061 [spa_namespace_lock] 4630.58r 0.00u 0.00s 0% 1756k load: 0.00 cmd: zpool 1061 [spa_namespace_lock] 5145.49r 0.00u 0.00s 0% 1756k and [root@johan ~]# zpool list load: 0.00 cmd: zpool 1257 [spa_namespace_lock] 2.03r 0.02u 0.00s 0% 1760k load: 0.00 cmd: zpool 1257 [spa_namespace_lock] 2.48r 0.02u 0.00s 0% 1760k and [root@johan ~]# zpool destroy tank load: 0.05 cmd: zpool 1262 [spa_namespace_lock] 46.71r 0.00u 0.00s 0% 1744k load: 0.05 cmd: zpool 1262 [spa_namespace_lock] 47.08r 0.00u 0.00s 0% 1744k >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
