--- Begin Message ---Package: parted Version: 2.2-5 Severity: normal i've got a logical volume exported by the device mapper which happens to be readable by a regular user. It's used as a block device for a VM, so it's got a partition table on it. I'd like to be able to modify that partition table without needing superuser privileges. However, parted appears to refuse to do it, even though the user is capable of reading and writing every block on the disk. The program itself even seems to think that this is a bug: bar@foo:~$ ls -la /dev/mapper/vg_foo0-bar brw-rw---- 1 root bar 253, 8 2010-04-15 04:42 /dev/mapper/vg_foo0-bar bar@foo:~$ /sbin/parted /dev/mapper/vg_foo0-bar WARNING: You are not superuser.
