Intel Xeon E3-1226 v3 @3.30GHz
booting from Intel 240GB SSD connected to motherboard Intel Lynx Point controller
Marvell 88SE9230 AHCI SATA Controller to manage four 3.0 TB WDC disc drives.
Originally, 4 x WDC WD30EFRX-68EUZN0 3.0 TB drives as /dev/ada0p1, /dev/ada1p1, /dev/ada2p1, /dev/ada3p1
Verified serial numbers of drives before attempting to remove/replace /dev/ada3p1 device
Offlined /dev/ada3p1, waited several minutes, shut down, replaced drive with WDC WD60EFRX-68L0BN1 6.0 TB drive, rebooted
Still have original 3.0 TB drive to replace, if absolutely necessary.
Current zfs pool status is:
Code: Select all
pool: zfsPool state: DEGRADED status: One or more devices could not be opened. Sufficient replicas exist for the pool to continue functioning in a degraded state. action: Attach the missing device and online it using 'zpool online'. see: http://illumos.org/msg/ZFS-8000-2Q scan: none requested config: NAME STATE READ WRITE CKSUM zfsPool DEGRADED 0 0 0 raidz2-0 DEGRADED 0 0 0 ada0p1 ONLINE 0 0 0 ada1p1 ONLINE 0 0 0 3661819670150165202 UNAVAIL 0 0 0 was /dev/ada2p1 1452713289130508182 UNAVAIL 0 0 0 was /dev/ada3p1 errors: No known data errors
2. Are there zpool commands I should use to bring the bottom two devices online again?
At the current time, this NAS handles media storage of MP3 audio and MP4 video plus a few megabytes of ordinary Windows shares via Samba, so it's not terribly dynamic and doesn't see a lot of activity. At this point, I'm heading to bed, and hoping for a helpful answer. Flames >>/dev/null please. If required, I can re-install the previous 3.0 TB drive as it's untouched since the shutdown and removal.
Thank you in advance for the benefit of your expertise.
