I have used blkid and added

/dev/md42: PTUUID="eb1b7eaf-b2ce-4ae6-9dbc-b77f58c1d75c" PTTYPE="gpt"


to fstab.

I am not sure why I am getting "PT" , but here is something I found in another forum

PTUUID is the UUID of the partition table itself, a unique identifier for the entire disk assigned at the time the disk was partitioned. It is the equivalent of the disk signature on MBR-partitioned disks but with more bits and a standardized procedure for its generation.





Now when I read blkid I am getting this - it identifies both /dev/md42 and the partition itself as /dev/md42p1

/dev/md42: PTUUID="eb1b7eaf-b2ce-4ae6-9dbc-b77f58c1d75c" PTTYPE="gpt"
/dev/md42p1: LABEL="MD42_RAID_LABEL" UUID="b4f937f3-8d8d-4d1b-a9e6-4eaffb72a077" TYPE="ext4" PARTLABEL="MD42_RAID_NAME" PARTUUID="49fce049-084f-48e8-aa79-f6e22d809879"


I do not get the mixing of UUID and PTUUID.

Should all this be added to fstab ?
