Dear Xfs,

Do I report this to you or Red Hat?

Fedora Core 26, x564

Here is fine, or Fedora if you want, but it'll be the same people responding in any case.

xfsdump-3.1.6-4.fc26.x86_64

When I run the following

    # /sbin/xfsdump -v verbose -M 1 -L 1 -l 0 -f /lin-bak/2017-08-19_22-30-27_md126p2.XfsDump  /

randomly, I get this error message when I run 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
    about 40 more of them

And the next time it will run clean.  What gives?

Most likely it's files that got deleted while xfsdump was running.  xfsdump has a bad habit of issuing warnings for things that are not actually problematic.

But you could also look for those inodes on the filesystem you're dumping; what are they?  Are they still there, or were they transient files?

If you quiesce the filesystem first, or dump from a snapshot, you should not see such errors.

I put a `sunc; sync` before the dump command and it seems to help, but it is random, so who knows.

Is this a bug?  Or am I doing something wrong?

Many thanks,
