This is another in the series of shrinking zpools. In this test, I’m repeating the previous test, only with UEFI, not BIOS, boot partitions. Partitioning root@r730-04:/home/dvl # gpart create -s gpt mfisyspd0 mfisyspd0 created root@r730-04:/home/dvl # gpart create -s gpt mfisyspd1 mfisyspd1 created root@r730-04:/home/dvl # gpart create -s gpt mfisyspd2 mfisyspd2 created root@r730-04:/home/dvl # gpart create -s gpt mfisyspd3 mfisyspd3 created root@r730-04:/home/dvl # gpart add -t efi -s 260M -a 4k mfisyspd0 mfisyspd0p1 […]

After succeeding with whole drives and with partitioned drives, I’m ready to try with more complex partitions. This is a repeat of the failed attempt a few days ago.

After yesterday’s failure to shrink a parition-based zpool. After reading this post, you want also want to read this other successful post. You will recall that expedition ended with: dvl@r730-04:~ $ zpool add zroot mirror /dev/da2p3 /dev/da3p3 cannot use ‘/dev/da2p3′: must be a block device or regular file Today, I’m going to try the same thing with whole disks, just to see if that works.

Today I was setting up some drives for testing. I did this manually: root@r730-04:~ # gpart create -s gpt da2 da2 created root@r730-04:~ # gpart add -t efi -s 260M -a 4k da2 da2p1 added root@r730-04:~ # gpart add -t freebsd-swap -s 8G -a 4k da2 da2p2 added root@r730-04:~ # gpart add -t freebsd-zfs -a 4k da2 da2p3 added root@r730-04:~ # gpart show da2 => 40 62533216 da2 GPT (30G) 40 532480 1
