Is there any reason to prefer GPT labels over glabel on the raw disk like so? NAME STATE READ WRITE CKSUM zfs ONLINE 0 0 0 raidz2 ONLINE 0 0 0 label/disk100 ONLINE 0 0 0 label/disk101 ONLINE 0 0 0 label/disk102 ONLINE 0 0 0 label/disk103 ONLINE 0 0 0 label/disk104 ONLINE 0 0 0 label/disk105 ONLINE 0 0 0 Could GPT labelled disks be read on a Solaris host without further modification?
