[Tommy Wu <wu.tommy@xxxxxxxxx>]

Hi!

   xfsdump 3.1.4

   xfsprogs 3.2.1

   linux kerenl 3.17/3.17.1

   xfsdump will create a small backup file in 3.17 (test in 3.17, 3.17.1).

   it report SUCCESS, like this:

   It just create  a small dump file, and if I run the same xfsdump again (or umount the filesystem), it will hang, like:

fw1:/vol/backup/fw1# /sbin/xfsdump -v trace,drive=debug,media=debug -l 0 -o -J -F - /dev/vg/root | gzip > test.gz
/sbin/xfsdump: using file dump (drive_simple) strategy

/sbin/xfsdump: session label: ""
/sbin/xfsdump: ino map phase 1: constructing initial dump list

   switch back to kernel 3.16, the same command work fine.
