Hi, I'm running FreeBSD 10.0 x64 on a Xeon E5 based system with 8GB RAM. Checking the ZPOOL status I saw one of my drives has been offlined... the exact error is this: # zpool status -v pool: ZPOOL_2 state: DEGRADED status: One or more devices has been removed by the administrator. Sufficient replicas exist for the pool to continue functioning in a degraded state. action: Online the device using 'zpool online' or replace the device with 'zpool replace'. scan: scrub repaired 0 in 9h3m with 0 errors on Sat Apr 5 03:46:55 2014 config: NAME STATE READ WRITE CKSUM ZPOOL_2 DEGRADED 0 0 0 raidz2-0 DEGRADED 0 0 0 da0 ONLINE 0 0 0 14870388343127772554 REMOVED 0 0 0 was /dev/da1 da2 ONLINE 0 0 0 da3 ONLINE 0 0 0 da4 ONLINE 0 0 0 I think this is due to a dead disk however, I'm not certain which is why I wanted to ask here as I didn't remove the drive at all..... rather then some kind of OS/ZFS error. The drives are 2TB WD Green drives all connected to an LSI HBA; everything is still under warranty so no big issue there and I have external backups too so I'm not really that worried, I'm just trying to work out what's going on. Are my suspicions correct or should I simply try to reboot the system and see if the drive comes back online? Regards, Kaya
