Duplicating a zpool

I have these boot drives, I want to copy them to another. They both happen to be zroot and bootable.

Dell R720 flashing Dell PERC H710 mini into IT mode

Dell PowerEdge Servers are common in #homelab use. The hardware gets sold after it goes out of warranty and they get dumped. Most of the disk cards in these servers come flashed for use with RAID and RAID only. Never use a RAID card with ZFS. Always give ZFS direct access to the drives. I …

In this post, I’m not exporting an iocage jail to another host. I am moving the entire iocage instance to another host. This is accomplished by doing a zfs export on the zpool, moving the drives to a new system, and doing a zfs import. The drive migration is covered in a previous post. In …

Migrating drives and the zpool from one host to another.

Today is the day. Today I move a zpool from an R710 into an R720. The goal: all services on that zpool start running on the new host. Fortunately, that zpool is dedicated to jails, more or less. I have done some planning about this, including moving a poudriere on the R710 into a jail. …
