Hello Forum,
I have a question regarding adding a new hard drive to an existing ZFS RAIDZ pool. Currently my storage is set up like so.....
3 X 1TB RAIDZ with 1 X 1TB as a hot spare, all 4 drives are identical. System boots from a USB thumbdrive.
On top of this I have
1 X ISCSI volume (500GB) which I use for VMWare
5 X NFS/CIFS volumes for backups, music, movies, iso images etc (reason for mixture of CIFS and NFS is so that both Windows and Linux systems can access the files easily)
I have come to the realization that the "spare" drive could be better used as part of the RAIDZ setup. What I want to do is add the hot spare to the pool, thereby giving me more available disk space. Has anyone been through this process ? I have a horrible feeling that you can't simply add a new drive to a RAIDZ pool and have to save everything off, destroy the pool and re-create with the 4 drives instead of 3 ? If this is the case will saving off the config enable me to quickly recreate my volumes/users/settings etc ??
Thanks in advance
