Ok this is bizarre: I have a mount (/mnt/hdf2) when I mount it, its mounr parameters are rw [$cat /proc/mounts: /dev/hdf2 /mnt/hdf2 ext3 rw,data=ordered 0 0].

As soon as I try to change any ownership [chown -R nobody.nobody /mnt/hdf2/<file or folder>] the mount changes to ro [$cat /proc/mounts: /dev/hdf2 /mnt/hdf2 ext3 ro,data=ordered 0 0] and I get: [chown: changing ownership of `/mnt/hdf2/<file>': Read-only file system]

WTF?!?!? why would any mounted filesystem change from rw to ro spontaneously? I unmount and remount and it comes back rw but changes as soon as I do any permissions change.

/etc/fstab has:
/dev/hdf2 /mnt/hdf2 ext3 defaults 1 2

Probably filesystem errors. Unmount it and fsck it.

[root@clearos mnt]# umount /mnt/hdf2
[root@clearos mnt]# fsck -a /dev/hdf2
fsck 1.39 (29-May-2006)
/mnt/hdd2: clean, 42875/2445312 files, 8230865/9770796 blocks


Clean. Any other ideas?

Force the fsck. fsck -f

Ok so I figured when I tried to mount as a windows share (samba) and copied a file to it , which of course complained. I did an 'lsof' just to see if there was any issue with any open files that might preclude me from copying to the mount. Here is what I found:

[root@clearos mnt]# lsof | grep '/mnt/hdf2'
smbd 4820 root cwd DIR 33,66 2048 2 /mnt/hdf2

So something in Samba was causing this issue. I stopped samba and changed perms.

Now on to other things....
