# need help with xfs error message [closed]

Hi All,

randomly, I get this error message when I run xfsdump:

# /sbin/xfsdump -v verbose -M 1 -L 1 -l 0 -f /lin-bak/2017-08-19_22-30-27_md126p2.XfsDump  /
/sbin/xfsdump: ino map phase 1: constructing initial dump list
/sbin/xfsdump: WARNING: failed to get bulkstat information for inode 739
/sbin/xfsdump: WARNING: failed to get bulkstat information for inode 954
/sbin/xfsdump: WARNING: failed to get bulkstat information for inode 1118

And the next time it will run clean. What gives? I put a sunc; sync before the dump command and it seems to help, but it is random, so who knows.
