Subject: xfs_db "frag" command gives segmentation fault

Date: Tue, 08 Nov 2005 20:26:31 +0100

Package: xfsprogs
Version: 2.6.36-1
Severity: normal

Hello Nathan,

using the "frag" command in xfs_db gives a segmentation fault here:

root@deepdance:/ -> xfs_db -V
xfs_db version 2.6.36
root@deepdance:/ -> xfs_db -r /dev/hda5
xfs_db> label
label = "debian"
xfs_db> frag
Speicherzugriffsfehler
(^^^ german for segmentation fault)

Using an older version of xfs_db from an chroot'ed SuSE 9.3
environment (same kernel running, see below) works instead:

deepdance:/# xfs_db -V
xfs_db version 2.6.25
deepdance:/# xfs_db -r /dev/hda5
xfs_db> label
label = "debian"
xfs_db> frag
actual 324362, ideal 321705, fragmentation factor 0.82%
xfs_db> quit
deepdance:/#

I am using a self compiled vanilla 2.6.13.4 kernel with the
following XFS options compiled in:

root@deepdance:/ -> grep -i "XFS" /boot/config-2.6.13.4-tp23
# XFS support
CONFIG_XFS_FS=y
CONFIG_XFS_EXPORT=y
CONFIG_XFS_RT=y
CONFIG_XFS_QUOTA=y
CONFIG_XFS_SECURITY=y
CONFIG_XFS_POSIX_ACL=y
# well not really XFS related
# CONFIG_VXFS_FS is not set

This is an strace of the bug:

The bug also happens when I use the "frag" command on a previously
unmounted partition.

Please tell me when you need any further informations.

Hi Martin,

I fixed this a little while ago in XFS CVS, but I've not yet
uploaded a new xfsprogs to the Debian archive.  I've got a few
other changes pending, so hopefully by weeks end I'll do this.

thanks.
