Hello! I'm trying to change the UUID on a ext4 formatted partition of a virtual machine disc. The machine is running under virtualbox, on Windows. I'm using "tune2fs /dev/sda3 -U random", or "tune2fs /dev/sda3 -U UUID". I have booted from the arch install disk, the partition is not mounted. When I run this command, I only get this: [root@archiso /]# ls /dev/disk/by-uuid/ -l total 0 lrwxrwxrwx 1 root root 10 2009-03-12 14:27 323cc148-ff48-4038-a2e7-9908896a58fd -> ../../sda2 lrwxrwxrwx 1 root root 10 2009-03-12 14:27 36628cd2-0842-4be0-a631-12afbc48793d -> ../../sda3 lrwxrwxrwx 1 root root 10 2009-03-12 14:27 93f768dc-9161-4387-a83d-231da5f193ef -> ../../sda1 [root@archiso /]# tune2fs /dev/sda3 -U 00f46b25-8c12-4254-8d45-13be848c3da1 tune2fs 1.41.4 (27-Jan-2009) [root@archiso /]# ls /dev/disk/by-uuid/ -l total 0 lrwxrwxrwx 1 root root 10 2009-03-12 14:27 323cc148-ff48-4038-a2e7-9908896a58fd -> ../../sda2 lrwxrwxrwx 1 root root 10 2009-03-12 14:27 36628cd2-0842-4be0-a631-12afbc48793d -> ../../sda3 lrwxrwxrwx 1 root root 10 2009-03-12 14:27 93f768dc-9161-4387-a83d-231da5f193ef -> ../../sda1 [root@archiso /]# Tune2fs does not give any error, but the UUID does not change. Any ideas? Best Regards, Guillermo Leira
