Zpool status -- why does a suboptimal pool show as "ONLINE"?

Hey there all, I have a nagios check that assumes that if I have a suboptimal zfs zpool, that the word “DEGRADED” will appear in the output. One disk of a two-disk mirror seems to have faulted, but the pool still shows as “ONLINE”. I know I’ve seen the word “DEGRADED” in the past. What’s different? pool: zroot state: ONLINE 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. config: NAME STATE READ WRITE CKSUM zroot ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 ada0p3 FAULTED 4 372 0 too many errors ada1p3 ONLINE 0 0 0 errors: No known data errors 14.1, if it matters, the disks are two innolite SATADOM’s. -Dan
