[Dump-devel] dump -W reports "DUMP: mount: bad UUID" for /boot/efi file system

[Josef R. <jr...@re...>]

Hi, 
I am new maintainer of dump package in Red Hat and Fedora.
This has been submitted to our Bugzilla: 

-----------------------------------------------------------------------------
Description of problem: dump -W reports "DUMP: mount: bad UUID" when attempting to inspect the /boot/efi file system.

Version-Release number of selected component (if applicable): dump.x86_64 1:0.4-0.6.b42


How reproducible: repeatable.


Steps to Reproduce:
1. Make sure you have a /boot/efi partition (mine was created by the installer).
2. # dump -W
  
Actual results:

# dump -W
  DUMP: mount: bad UUID
Last dump(s) done (Dump '>' file systems):
  /dev/sda7     (     /) Last dump: Level 0, Date Tue Jan 15 05:43:37 2013
  /dev/sda2     ( /boot) Last dump: Level 0, Date Tue Jan 15 05:44:12 2013
  /dev/sda9     (   /db) Last dump: never
  /dev/sda3     ( /home) Last dump: Level 0, Date Tue Jan 15 12:06:14 2013
  /dev/sda4     (  /tmp) Last dump: Level 0, Date Tue Jan 15 12:51:33 2013
  /dev/sda5     (  /usr) Last dump: Level 0, Date Tue Jan 15 12:51:36 2013
  /dev/sda6     (  /var) Last dump: Level 0, Date Tue Jan 15 12:53:26 2013

The /boot/efi file system that is present (and mounted) is not reported by dump.

#  mount
/dev/sda7 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
/dev/sda2 on /boot type ext4 (rw,nodev)
/dev/sda1 on /boot/efi type vfat (rw,nosuid,umask=0077,shortname=winnt)
/dev/sda9 on /db type ext4 (rw,noexec,nosuid,nodev)
/dev/sda3 on /home type ext4 (rw,nosuid,nodev)
/dev/sda4 on /tmp type ext4 (rw,noexec,nosuid,nodev)
/dev/sda5 on /usr type ext4 (rw,nodev)
/dev/sda6 on /var type ext4 (rw,nosuid,nodev)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

Expected results:

The error "  DUMP: mount: bad UUID" ought not to be reported.
-----------------------------------------------------------------------------------

I am not sure, if is this bug, because dump does not support FAT/VFAT file system.

Can anyone confirm this or help me how to solve this problem?
Thanks
