Hi There,

I have been running Nas4Free with ZFS Raid Z1 using 3 x 1,5 TB and a single 3TB. I have now just attempted to replace the one 1,5TB on ada1 with a new 4TB drive using the method described by http://www.bolsondigital.com/2013/06/01 ... -nas4free/.

Any thoughts on how to bring my degraded set up again?


In short, I
zpool offline Backup ada1

Powered down the HP Microserver
Replaced the drive
And power up again.

Using disk management, I imported the new config and saved it to give the following:

Disk Size Description Device model Serial number Standby time File system Status
ada0 2861589MB ST3000DM001-9YN166 CC4B ST3000DM001-9YN166 S1F0JQKG Always on ZFS storage pool device ONLINE

ada1 3815448MB ST4000DM000-1F2168 CC52 ST4000DM000-1F2168 Z300E167 Always on Unknown or unformatted ONLINE

ada2 1430800MB ST31500341AS CC3H ST31500341AS 9VS1P9QR Always on ZFS storage pool device ONLINE

ada3 1430800MB ST31500341AS CC1H ST31500341AS 9VS2MDJF Always on ZFS storage pool device ONLINE

da0 7648MB Kingston DataTraveler 2.0 1.00 Kingston DataTraveler 2.0 1.00 001372877298A9B15678017A Always on UFS ONLINE


Using the
zpool online Backup ada1
and
zpool replace Backup ada1

did not give me any positive results.

Using zpool status gives:
zpool status

Any thoughts on how to

zpool online -e ada1

Thanks, just tied it but seems like this didn't work either.

In the Gui under ZFS tools Replace and Online, my ada1 does not appear either?

Just for the record:

The following solved the problem

zpool replace Backup 6882724504218657653 ada1.nop

Obviously, this is the information we were missing
