[PVE-User] Mirrored ZFS Boot drive?

[PVE-User] Mirrored ZFS Boot drive?

[Lindsay Mathieson]

When I setup my latest server, I used ZFS for the boot SSD.


I later added a 2nd SSD mirror, but of course that only mirrors the 
rpool, not the boot partions (2 of them?), so not as useful as I 
thought, as if the first SSD fails, the server won't boot :(


If I installed proxmox using mirrored SSD's from the start, would that 
setup a "dual" boot option on both SSD's or would one still be the 
primary and only boot device?

I tested this out, adding a 2nd ssd,  server is using efi/systemdboot, 
worked a treat. I even zapped and removed the first SSD, it still booted 
fine.


Thanks!
