Summary: xfs-admin/xfs_db segfaults with garbage partition
Product: Linux XFS
Version: Current
Platform: PC
OS/Version: Linux
Status: NEW
Severity: minor
Priority: P2
Component: xfsprogs
AssignedTo: xfs-master@xxxxxxxxxxx
ReportedBy: dick@xxxxxxxxxxxx
I'm using GNU/Linux Debian sid with xfs version Version: 2.8.18-1.
If I do xfs_admin -u /dev/mapper/vg01-crypto where vg01-crypto is a luks
encrypted partition (i.e. garbage to xfs) I get the following output:
xfs_admin: unexpected XFS SB magic number 0x4c554b53
xfs_admin: size check failed
xfs_admin: read failed: Invalid argument
xfs_admin: data size check failed
cache_node_purge: refcount was 1, not zero (node=0x80e2208)
xfs_admin: cannot read root inode (22)
cache_node_purge: refcount was 1, not zero (node=0x80e22f8)
xfs_admin: cannot read realtime summary inode (22)
/usr/sbin/xfs_admin: line 28: 10100 Segmentation fault (core dumped) xfs_db
-x -p xfs_admin -r -c uuid /dev/mapper/vg01-crypto
As one might expect symptoms depend on specific partition. On other crypto
partitions I get just:
xfs_admin: unexpected XFS SB magic number 0x4c554b53
Floating point exception (core dumped)
N.B. This problem gives me no grief at all - I just noticed in passing.
