Add Second HDD

M

mezzobob

Hi, I'm new to FreeBSD,

I installed FreeBSD with ZFS on my system. Now I want to add a Second HDD to the system. At this moment the second disk is formatted with HFS+.
How can I delete the disk an add it to the FreeBSD system with ZFS?

If you want to, blank out the second disk with dd, by overwriting all of adax (in your case, the "new" disk seems to be ada0, judging by the messed-up partition table containing a HFS file system). This is not necessary, but I like to start with blank disks. There is risk ... if you blank the wrong disk, your other disk is gone. Expect this to take about an hour.

Then, partition the new disk: gpart add -t freebsd-zfs -a 4K -l pickYourFavoriteNameForIt -s xxxG ada0. Pick a sensible size, thinking about whether you want to leave some spare space for later. I think if you omit the -s option, the partition will use the whole disk, but I'm not sure (read the man page yourself).

Now add that new partition to your ZFS file system. If you want to just make the existing pool bigger, then just do zpool add oldPool adaXsY. But if you have enough disk space, I would do mirroring instead (safer against disk failure), and use zpool attach oldPool adaXsY. Before you make that decision, learn about ZFS.
