While we do what we can to guarantee that they are installed properly in userland (CVS HEAD), we want to make sure that mount still aborts properly. The only sign of missing helpers is that lock_dlm will receive no mount options at all. According to David the problem does not exists for lock_nolock as the helpers are not required. The patch has been tested for both gfs and gfs2 and it works as expected. The lack of mount.gfs* will generate an error that is propagated to mount: root at node1:~# mount -t gfs2 /dev/nbd2 /mnt/ mount: wrong fs type, bad option, bad superblock on /dev/nbd2, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so [ 3513.303346] GFS2: fsid=: Trying to join cluster "lock_dlm", "gutsy:gfs2" [ 3513.304546] DLM/GFS2/GFS ERROR: (u)mount helpers are not installed properly! [ 3513.306290] GFS2: fsid=: can't mount proto=lock_dlm, table=gutsy:gfs2, hostdata= You might want to notice that it will also avoid mount to hang or fail silently or with strange errors that will require the cluster to reboot/restart before you can actually mount the filesystem again. Please apply. Signed-off-by: Fabio M. Di Nitto Thanks Fabio -- I'm going to make him an offer he can't refuse. -------------- next part -------------- A non-text attachment was scrubbed...
