Subject: all the history
Hi,
Following is the history:
The whole history is I found a ZIL device offline at about 2:00PM today from
syslog.
And I removed and replaced it with a backup device. But I mis-typed the adding
command like ?C ??zpool add cn03 c22t2d0?? and correct command should be ??
zpool add cn03 log
c22t2d0??. The ZIL was wrongly added as a data device in cn03 pool. I noticed
it so I physically
removed this device from server as I think raidz2 can afford this.
The commands I issued are ??zpool add cn03 c22t2d0?? and ??zpool add ?Cf cn03
c22t3d0??
But the tragedy is coming, the cn03 whole pool is corrupted now:
zpool import
pool: cn03
id: 1907858070511204110
state: UNAVAIL
status: One or more devices are missing from the system.
action: The pool cannot be imported. Attach the missing
devices and try again.

Additional devices are known to be part of this pool, though their
exact configuration cannot be determined.
Thanks.
