Hi,
We are seeing problems with xfsdump hanging in "D" state on a 1.3TB
filesystem.
This hang seems to happen at more or less random points in the dump.
I ran
xfs_check on the filesystem and it did not find problems. This
filesystem was
most likely created under RedHat 8.0 with XFS 1.3.0. This happened on
SuSE 9.0
with kernel version 2.4.21-215-smp4G and xfsdump version 2.2.13-33 and
now on
SuSE 9.1 kernel version 2.6.4-54.5-smp and xfsdump version 2.2.16-30.
Once
the xfsdump gets hung running strace or gdb on the process just hangs
so I can't
tell where the process is getting stuck.
Has anyone seen this? Any ideas on a fix or any suggestions on
further debugging
this issue?
There are a fair number of files on this filesystem, here's the
output from
"df -i":
df -i /dev/sda1
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/sda1 693847296 10842420 683004876 2% /data
Here's the output from xfs_info on this partition:
xfs_info /dev/sda1
meta-data=/data isize=512 agcount=331, agsize=1048576 blks

log =internal bsize=4096 blocks=32768, version=1

realtime =none extsz=65536 blocks=0, rtextents=0
Here's the command line I used:
/usr/sbin/xfsdump -l 0 -T -e -d 2048 -o -L glimpse10 -Y 7 -f
guest@tapehost:/dev/nst0 /dev/sda1
(I know that "-Y 7" doesn't do anything under Linux, it's just a
holdover
from my old IRIX scripts)
