Hi list,
I have a serious issue with my zpool.
My zpool consists of 4 vdevs which are assembled to 2 mirrors.
One of this mirrors got degraded cause of too many errors on each vdev
of the mirror.
Yes, both vdevs of the mirror got degraded.
According to murphys law I don't have a backup as well (I have a
backup, which was made several months ago, and some backups spread
across several disks)
Both of these backups are not the best so I want to access my data on
the zpool so I can make a backup and replace the opensolaris server.
As the two faulted vdevs are connected to different controllers I
assume that the problem is located on the server, not on the harddisks/
controllers....one of the faulted harddisks has been replaced some
weeks ago due to crc errors, so I assume the server is bad, not the
disks/cables/controllers.
My state is as follows:
NAME STATE READ WRITE CKSUM
performance DEGRADED 0 0 8
mirror DEGRADED 0 0 16
c1t1d0 DEGRADED 0 0 23 too many errors
c2d0 DEGRADED 0 0 24 too many errors
mirror ONLINE 0 0 0
c1t2d0 ONLINE 0 0 7
c3d0 ONLINE 0 0 7
The disks (at least the c1t1/2 ones,I don't see the c2/3 ones via
cfgadm) are online as fare I can see via cfgadm.
Is there a possibility to force the two degraded vdevs online, so I
can fully acces the zpool and do a backup?
I wanted to ask first, before doing any stupid things and to loose the
whole pool.
Any suggestions are very welcome.
