Not really expected... It is reading the "mountdata" file via debugfs, so that should be safe even on a mounted filesystem, but it doesn't work with MMP: # debugfs -c -R stats /dev/vgbackup/lvtest debugfs 1.41.10.sun2 (24-Feb-2010) /dev/vgbackup/lvtest: MMP: device currently active while opening filesystem stats: Filesystem not open This is already fixed in our next release of e2fsprogs, however, thanks to a patch Jim Garlick @ LLNL. It is the first hunk of the patch at: https://bugzilla.lustre.org/attachment.cgi?id=30441 > mds1-gps:~ # tunefs.lustre --print /dev/mapper/mdt1 > checking for existing Lustre data: not found > > tunefs.lustre FATAL: Device /dev/mapper/mdt1 has not been formatted with > mkfs.lustre This error message should probably be fixed also.
