Public bug reported:
Binary package hint: gparted
A system with two physical disks (sda, sdb), each with valid UUID.
Problem:
Gparted overwrites a valid UUID on destination disk if partition is copied
using Gparted. Result is two partitions with same UUID i.e. "Unique
Identifier" is no more unique. That will result in some other problems which
show up like described in bug report # 579703 for example.
Further details:
Gparted version is 0.7. Steps I did: Ubuntu 10.10 system partition (/) on
disk "sda" was getting fulll and I added another physical disk "sdb" which was
before used in another Ubuntu installation with valid partition. "sdb" was
working ok after boot. Decided to copy Ubuntu system partition from "sda" to
"sdb" and modify boot to use "sdb" for Ubuntu since there is enough space.
Idea did not succeed since Gparted had overwritten original UUID on disk "sdb"
i.e. there are now two partitions on different disks with same UUID. Please
see this printout fron "sudo blkid":
/dev/sda1: LABEL="C_DRIVE" UUID="F614D11C14D0E0A3" TYPE="ntfs"
/dev/sda2: UUID="33111f1c-9438-4b9b-a61d-015ab998224c" TYPE="swap"
/dev/sda3: LABEL="10.10-root" UUID="144ec3ef-55a7-4ede-a2ef-3f284abbf680"
TYPE="ext3"
/dev/sda4: LABEL="10.10-home" UUID="5589dba1-5f3b-4581-b24a-8ba4b3a86c50"
TYPE="ext3"
/dev/sdb1: LABEL="10.10-root" UUID="144ec3ef-55a7-4ede-a2ef-3f284abbf680"
TYPE="ext3"
