Could you refer me to an article > or a discussion where this issue is described ? The GPT backup partition tables goes at the end of a disk, the same place gmirror(8) and other GEOM modules keep metadata. If GPT partitions are created inside a mirror, the backup GPT table is no longer at the end of the disk. Hiroki Sato created a patch which fixed the gptboot complaints, but there was concern about the nonstandard location of the backup table. At present, MBR partitioning is recommended with gmirror(8).home | help
