Re: xfs_repair on a 1.5 TiB image has been hanging for about an hour, now

The -P option allowed me to complete xfs_repair successfully, but it
also deleted almost everything on the filesystem... A directory that I
could mount -o ro,norecovery before, with tens of GB of data in it, is
now empty... That is really too bad.

Thanks for your help.
