What to do after HDD crash and zfs replace

big_blue · Oct 21, 2024, 3:12 PM

Hi.
I am very new in freeBSD and pfSense. I had a HDD crash and was able to mount the pfSense again because of ZFS mirror. No i added a new HDD and was able to resync the zfs volume. Is there something else if have to do?

Efi Boot install on new HDD or something like this?

What i have done until now is. I created the same partition schema like the "original" one with the following command:
gpart backup ada0 | gpart restore -F ada1

Afterwards i replace the zfs volume with the new one:
zfs replace pfSense ada1p4 ada1p4

Now the pool is in status online and there everythink looks ok. But i am not sure if the new HDD is now able to used a startvolume.

this is my current partitioning created with the default installer:

Looks good there.

big_blue · Oct 21, 2024, 6:06 PM

Yes, and there is nothing more to do? Is this device now bootable?

stephenw10 · Oct 21, 2024, 6:31 PM

Yes I would expect it to be. If the pool shows as good and all members of the pool as good.

big_blue · Oct 21, 2024, 6:41 PM

Ok, thank you very much. I will give it a try tomorrow.
