HOW TO: Find the UUID for your partitions

[Patrick K]

Type "blkid" in a terminal. It returns the UUID for all partitions.

[jdong]

Also, vol_id -u /dev/real_name returns the UUID of any block device

(blkid fails on NTFS drives)

I tried your command and got this in return:

"error open volume"

Both with properly mounted partitions and unmounted volumes. Nothing was visibly running that would have these partitions open. Although I don't know that that should matter.

with the vol_id you need administrative powers. Run it with sudo.

With sudo I get "unknown vloume type".

I think you are doing some mistake, Here is my output,

chaks@chaks-laptop:~$ sudo vol_id /dev/sda4
ID_FS_USAGE=filesystem
ID_FS_TYPE=ext3
ID_FS_VERSION=1.0
ID_FS_UUID=961c6d4f-79c9-4edf-a774-d394c7384fa7
ID_FS_LABEL=
ID_FS_LABEL_SAFE=

I think it does not return UUID for Windows Partition. To be more clear, here is the output,

chaks@chaks-laptop:~$ sudo blkid 
/dev/sda1: TYPE="ntfs" 
/dev/sda3: UUID="faff795a-7767-4e57-bc84-4ea62fd4c2f1" SEC_TYPE="ext2" TYPE="ext3" 
/dev/sda4: UUID="961c6d4f-79c9-4edf-a774-d394c7384fa7" SEC_TYPE="ext2" TYPE="ext3" 
/dev/sda5: TYPE="ntfs" 
/dev/sda6: TYPE="ntfs" 
/dev/sda7: UUID="f6ba4a42-67e2-4d68-acc5-a1424e1d5082" TYPE="swap" 
/dev/sda8: UUID="b4456ccd-3ae9-44fd-9499-0a33fbae8683" SEC_TYPE="ext2" TYPE="ext3" 
/dev/sdb1: SEC_TYPE="msdos" UUID="0000-0000" TYPE="vfat" 
chaks@chaks-laptop:~$ sudo vol_id /dev/sda1
ID_FS_USAGE=filesystem
ID_FS_TYPE=ntfs
ID_FS_VERSION=3.1
ID_FS_UUID=46E435E7E435D9BF
ID_FS_LABEL=
ID_FS_LABEL_SAFE=

The vol_id does give UUID for /dev/sda1 than blkid

[Patrick K]

With vol_id I still just get

pk@pk-desktop:~$ sudo vol_id /dev/sda5 /dev/sda5: unknown volume type

With blkid this is what I get

pk@pk-desktop:~$ blkid
/dev/sda1: LABEL="WIN98" UUID="0000-0E54" TYPE="vfat" 
/dev/sda5: LABEL="ELF" UUID="0000-0E74" TYPE="vfat" 
/dev/sda6: LABEL="FACTOID" UUID="0000-0E75" TYPE="vfat" 
/dev/sda7: LABEL="GADZOOKS" UUID="0000-0E5F" TYPE="vfat" 
/dev/sda8: UUID="e1484135-3eb4-4f17-b03c-5e1e0d88b480" TYPE="swap" 
/dev/sdb1: LABEL="DIONYSUS" UUID="0000-0ED9" TYPE="vfat" 
/dev/sdb6: LABEL="JOVE" UUID="0000-0D8B" TYPE="vfat" 
/dev/sdb7: LABEL="FAVS" UUID="0000-0ED9" TYPE="vfat" 
/dev/sdb8: LABEL="FAVS2" UUID="0000-0D85" TYPE="vfat" 
/dev/sdb9: LABEL="MOVIES" UUID="0000-0D47" TYPE="vfat" 
/dev/sda9: LABEL="HAM" UUID="4598-9D46" TYPE="vfat" 
/dev/sda10: UUID="063da081-4ed5-4c75-a789-81de30b946bb" SEC_TYPE="ext2" TYPE="ext3" 
/dev/sda11: UUID="9f8d6e0b-f3b0-40e3-9e26-b3dcc3f84410" SEC_TYPE="ext2" TYPE="ext3" 
/dev/sdb5: SEC_TYPE="msdos" LABEL="TEMP" UUID="0000-0DAA" TYPE="vfat"

Blkid shows vfat volumes on my system.

Ofcourse vol_id is correct. Becoz, for your partition entries, /dev/sda5 should be the starting of the extended partition.

Can you please post the output of sudo fdisk -l
