I see we only left 64K for the boot part. It's big enough for us for now, but possibly we should fix that as well. We have a mirror setup for system disks so we have the ability to take each system drive offline one at a time and rearrange it and then re-add the root partition to the mirror. What are the chances a regular gpt+ZFS (no encrypt) bootblock will grow over 64K? > > -Ngie > _______________________________________________ > freebsd-current@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" >
