finding mount points owners

[andi_1]

Hi,

How can I find out ownerships of the mount points on a any system?

Thank you.

for nfs mounts:

showmount -a
and
showmount -d

for local mounts

mount

Umount the filesystem and then do an ls -l on the mountpoint itself.

Hi,

I don't think mount command will work. It doesn't say what group and owner does specific mount belongs to.

Hi,

There is no command to find the owner and group of a mount point. Try the simplest way, first do a "bdf" to find the mount point and then do a "ll" to check for the owner and group for the mount point.

Hope this helps.

Hi,

The ownership/permissions can be found by 'ls -al' on the mount point.

If you have ACL's then use 'lsacl' command.

While mounting, you are not assigning any permissions there, it is assigned just like you assign permissions to a directory.

hi,

do a bdf | grep -v Filesystem | awk '{print $6}'

on the output which is the mountpoint, do a ll -d

That tells the owners/permissions.

Ofcourse, this is assumign that the filesystem is mounted!

Not sure about the reason for the question, but also be aware of the fact that mounted filesystems have permissions as well as the mount points themselves. So my recommendation is to use some scheme to get a listing of the filesystems (maybe use the bdf | grep | awk) method mention earlier in this thread and do an ls -ld on that listing. Then when you have a chance to do this with the filesystems unmounted, do the same.

I have seen cases where the permissions were different and everyone could read and write to a mount point when the filesystem was not mounted and mysteriously (/) would fill up and no one could find the cause. HINT: after the ls -ld with the filesystems unmountd a du -ks on the same mount points might be in order.

Good Luck,

Miguel
