SOLVED Volume status DEGRADED, can't replace with spare

[beria]

Hello All,

I've got problem to swap broken disk with failed one. I've got following volume:

[root@KWITSTNAS01] ~# zpool status -x
pool: vol1
state: DEGRADED
status: One or more devices could not be opened. Sufficient replicas exist for
the pool to continue functioning in a degraded state.
action: Attach the missing device and online it using 'zpool online'.

But when I've tried:

zpool vol1 replace 216606963221122002 gptid/ddb32705-93c2-11e3-971e-002590ca2e10

I've lost this array for two days (I mean this array serving one big disk via iSCSI to windows machine, and this disk was unavailable for two days), and nothing happend. During this two days FreeNAS was totally unresponsive.
So I've decided to reboot this, since 2 days is too much time. After reboot evertything is OK (except zpool status as above).

So my question here is: how to gently replace this broken disk?

The manual has instructions for replacing a failed disk--did you try those before you started messing around with the CLI?

Actually, yes.

Beforme messing with CLI, I've tried to swap disks via GUI - no luck. (spare disks where not visible in replace dialog window).

But finally after this morning reboot, I was able to do this via GUI.
I'm not sure why this problem occur. And also my nice uptime was gone :/ (389 days)
