Re: cause of xfsdump msg: root ino 192 differs from mount dir ino 256

[L A Walsh <xfs@tlinx.org>]

The restore finished, the beginning is:
xfsrestore: using file dump (drive_simple) strategy
xfsrestore: version 3.1.8 (dump format 3.0)
xfsrestore: searching media for dump

...
there are a bunch of lines like that, 'wc' on the file shows:

> wc /tmp/xfsrestore.log 
  5320822  50100130 821050625 /tmp/xfsrestore.log

Then the end of the file looks like:

xfsrestore: NOTE: ino 8485912415 salvaging file, placing in orphanage/256.0/tools/samba/samba-4.14.2/third_party/resolv_wrapper/wscript
xfsrestore: WARNING: unable to rmdir /nhome/./orphanage: Directory not empty
xfsrestore: restore complete: 7643 seconds elapsed
xfsrestore: Restore Summary:
xfsrestore:   stream 0 /backups/ishtar/home/home-211101-0-0737.dump OK (success)
xfsrestore: Restore Status: SUCCESS

The lines in between beginning and end appear to be 
an incrementing inode & file list of the disk as it was
put into the orphanage

The restored file system appears to slightly larger, but
that's likely because I cleared off some garbage from the
current home.

Ah, the xfsdump just finished:

Except for the 5.3 million lines between the start+end, the xfsrestore output is above.

I can't imagine why you'd want the 5.3 million lines of
file listings, but if you do, I'll need to upload it somewhere.
