[OpenIndiana-discuss] pool messup

[Roy Sigurd Karlsbakk]

Hi all

I have this box for backup storage, urd-backup, zfs receiving a copy of another system, urd. on urd-backup, I created the following pool

zpool create -f urd-backup \
        raidz2 c5t0d0 c5t1d0 c5t2d0 c5t3d0 c5t4d0 c5t5d0 c5t6d0 c5t7d0 c5t8d0 \
        raidz2 c5t9d0 c5t10d0 c5t11d0 c5t12d0 c5t13d0 c5t14d0 c5t15d0 c5t16d0 c5t17d0 \
        raidz2 c5t18d0 c5t19d0 c5t20d0 c5t21d0 c5t22d0 c5t23d0 c5t24d0 c5t25d0 c5t26d0 \
        raidz2 c5t27d0 c5t28d0 c5t29d0 c5t30d0 c5t31d0 c5t32d0 c5t33d0 c5t34d0 c5t35d0

Something recently happened, and the pool was suddenly showing lots of bad drives. Also, it now shows the drives in different order than the original, which I find rather alarming. I also get an error message when trying to zpool replace a drive to attempt a forced resilver of that. See below the zpool status output for this.

Does anyone know what on earth could have caused this, and how I can fix it?

root at urd-backup:~# zpool status urd-backup

 state: DEGRADED
status: One or more devices are faulted in response to persistent errors.
        Sufficient replicas exist for the pool to continue functioning in a
        degraded state.
action: Replace the faulted device, or use 'zpool clear' to mark the device
        repaired.

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med fremmed opprinnelse. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
