Hmm, it doesn't seem to last more than a couple hours
under test load (mapped as a CIFS share receiving a
bittorrent download with 10 k small files in it at
about 10 MByte/s) before falling from the pool:
root@nexenta:/export/home/eugen# zpool status tank
pool: tank
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.
scan: none requested
config:
