Description Richard W.M. Jones 2013-08-08 17:32:21 UTC 
+++ This bug was initially created as a clone of Bug #986877 +++

Description of problem:

Currently UUIDs on ext2/3/4 filesystems can be set using the special
set-e2uuid command.  However it's possible to set these as well for
XFS (using xfs_admin -U ...).  We should implement a generic set-uuid
call which can handle either.

Fixed/implemented upstream:

https://github.com/libguestfs/libguestfs/commit/091d22f49e7fcb53fb3bb23e2ba94ca12eb88eab
https://github.com/libguestfs/libguestfs/commit/8580ef7d0f2aac2118fa7b4055f3eb28cd127093
https://github.com/libguestfs/libguestfs/commit/df02c2471f3fe94c691c389c17a5d23d052848dd
https://github.com/libguestfs/libguestfs/commit/8965368eb89532ac1613fffb0a3a661f005bae81

NB: the fs-uuids patch (last one in that list) is broken.  Fixed
by a later patch upstream:

5deea7fce675edb6803cd83a699b80e8ea383488

So either both or neither of those should be applied.

Verified with libguestfs-1.22.6-16.el7.x86_64

# guestfish -N fs:xfs set-uuid /dev/sda1 9a804901-5f19-4b0c-808a-f00c498599fb : get-e2uuid /dev/sda1
9a804901-5f19-4b0c-808a-f00c498599fb


set-uuid works for xfs
