Replace bootable disk in Raidz1 with bigger one

[Ray_]

Hey,

I need to replace the boot disks from my node. I know of the normal way described here but since sgdisk -R simply copies the partitions the main partition size wouldn't match the new diskspace.

Is there a recommended way of increasing the size afterwards?

I wrote a script for replacing mirrored zfs boot/root with smaller drives, should give you some ideas:

With the pool exported, you could move the end of the partition with parted

You should set autoexpand=on beforehand, or you may need to do a zpool online -e to have it use the expanded space
