[Moosefs-users] Question about mounting suid,dev

[Ricardo J. B. <ric...@da...>]

Hello, list.

I need to mount a filesystem with suid enabled and found I can't do it from
fstab: mo matter what options I set there, the mount always uses nosuid,nodev
which are fuse's default.

This is in my /etc/fstab:

mfsmount  /opt  fuse  defaults,noatime,suid,nodev,_netdev,mfsmaster=master,mfssubfolder=/  0 0

And this is in /proc/mounts:

mfs#master:9421 /opt fuse rw,nosuid,nodev,noatime,user_id=0,group_id=0,default_permissions,allow_other 0 0

However, if I mount it with:

mfsmount -o noatime,suid,nodev /opt -H master -S /

I got this in /proc/mounts:

mfs#master:9421 /opt fuse rw,nodev,noatime,user_id=0,group_id=0,default_permissions,allow_other 0 0

I have tried putting "suid" in /etc/mfs/mfsmount.cfg on the client but it
makes no difference when using fstab.

All this is with CentOS 5.8 64 bits servers and a CentOS 5.8 32 bits client
but it also happens in a CentOS 5.8 64 bits client, all of them running
mfs-1.6.24 installed from RepoForge RPMs and fuse 2.7.4 from standard CentOS
repositories.


According to fuse's README:

"Filesystems are mounted with '-onodev,nosuid' by default, which can only be
overridden by a privileged user."

But I'm mounting MFS as root from command line.

Is this a bug in MFS? fuse? me?

Thank you,
