Hi,
I know that it is old post but I believe my experience is corresponding
with the mentioned problems:
Every-time when I rearranged internal/external/usb hard disk/s
partition/s (for example for RAID0 array/s blkid always had wrong info).
It happened all the time from natty to precise distro ubuntu. For ubuntu
original compiled kernel from 2.6.x.x to 3.2.x.x versions.
Just small example from today:
blkid|sort
...
/dev/sdl1: LABEL="EFI" UUID="cfb104a6-6b8d-46d1-b75b-1ef00a3f59ef" TYPE="ext2"
/dev/sdl2: UUID="3c9cec88-bb36-44af-b303-671c8e985d7e" TYPE="swap"
/dev/sdl3: UUID="6ab6304e-ca1c-f4d0-5749-0a6711686b87"
UUID_SUB="c56352cc-1535-d113-e3ff-177997f66d65" LABEL="UBU2TBEXT42:raid0ocz"

UUID_SUB="8eacee1a-3217-7ed7-e22b-76fc61b0bb05" LABEL="UBU2TBEXT42:raid0ocz"
TYPE="linux_raid_member"
compared to:
gdisk -l /dev/sdl /dev/sdm /dev/sdn /dev/sdo
...
Disk identifier (GUID): EF900EC5-4F8E-47D0-875E-6A261FC2F413
...
Number Start (sector) End (sector) Size Code Name
1 34 117226304 55.9 GiB FD00 PCEUBU1:raid0ocz
...
(just noticed - the same UUID for all four partitions, different label
name )
--- my experience:
gparted - shows wrong labels and UUIDs
gnome disk utility - shows proper information
blkid command - shows wrong information
gdisk - shows proper information
-- for all previous it happened even after reboot.
-- I remember those problem have appeared in grub prompt either ( when set root
= (tab key)
or showing wrong information for blkid in initramfs prompt.
(for blkid:
before reboot blkid/gparted shows wrong TYPE="" of partition)
after reboot blkid shows properly TYPE="linux_raid_memeber")
(I have created more than 50 RAID0 arrays within last year - it behaves
always the same way for blkid command)
