Summary: unable to copy a 25GB-file from xfs
Product: Linux XFS
Version: Current
Platform: All
OS/Version: Linux
Status: NEW
Severity: major
Priority: Medium
Component: XFS kernel code
AssignedTo: xfs-master@xxxxxxxxxxx
ReportedBy: Henning.Rohde@xxxxxxxxxxxxxxx
trying to backup the filesystem that is dedicated to vmware, i'm unable to get a
funktionable copy of the vmware-diskimage: vmware dislikes the copy, md5sums
differ between source and destination
there's no difference how the disk-image was copied:
- "xfs_copy /dev/$sourcepart /dev/$destpart"
- "xfsdump $source-mountpoint | xfsrestore $dest-mountpoint"
- "cp -a /path/to/$sourcefile /path/to/$destfile"
- "cat /path/to/$sourcefile > /path/to/$destfile""
- "tar -cf - ./$sourcefile | (cd $dest-mountpoint ; tar -xf - )"
xfs_check and xfs_repair are unable to find any problem on the source-partition,
the same on the dest-partition in the case the partition was backup'ed with
xfs_copy or "xfsdump|xfsrestore".
a binary copy with "/bin/dd if=/dev/$sourcepart of=/dev/$destpart bs=1024"
results in an usable copy on the dest-partition
the source-filesystem was created at installing SuSEv9.1 with fix from
http://portal.suse.com/sdb/en/2004/04/91_xfsfix.html,

thanks for help in advance,
Henning Rohde
