Hi Julien -
Your log file says:
"Start xfs_repair with cmdline: xfs_repair -L -m 8047 /dev/sdb"
1) Why did you use -L, would the log not replay?
2) Why use -m? Does that affect the outcome at all?
3) You could give the for-next branch in git a try, just in case, but otherwise
4) Please provide a compressed xfs_metadump for me to look at, off list, and
I'll see what I can find.
Thanks,
-Eric
