Can't mount disk volume because "no owner"

Help! I have 3 accounts on my iMac, one of them "Guest" with minimal privileges. That account mounts firewire attached disks, and in one of disk-volumes I changed ownership and permissions to "no access" and flagged off "Ignore ownership on this volume" (I think remembering).
Result: After switching to my normal (administrator) account, the volume will not mount anymore for any user, incl myself on administrator account! Disk utility verifies the volume ok and says "nothing to repair", the only clue being the info: Owners enabled: No.

Disk utility has greyed out "Repair disk permissions" so I am stuck. Tried to to reboot of course.
The volume contains my main back up, mirrored, 600 GB, so help is appreciated!

iMac Intel 2 GHz Core Duo, Mac OS X (10.4), FC Studio 2, FCE

Hi mark,

Easiest way get BatChMod...

http://www.versiontracker.com/dyn/moreinfo/macosx/12057&vid=268431&mode=info

In finder, select Go menu>Go to Folder, and go to "/volumes".

Volumes is where an alias to your hard drive ("/" at boot) is placed at startup, and where all the "mount points" for auxiliary drives are created for you to access them. This folder is normally hidden from view.

Drag that Volume to Batchmod's window... set the rights again.

Many thanks BDAqua. Exactly right. I'll donate to BatChMod.

Allow me one follow-up question: I understand that a group is a list of accounts having the same privileges, which you can define in the Info window or with BatChMod. But how do you assign members to a group?

Great news, thanks! 🙂

Two ways, easiest is likely Sharepoints...

The other way is with NetInfo Manager...

I deleted my /Volumes
how can I get it back?

xserve:~ root# mkdir /Volumes
mkdir: /Volumes: File exists
xserve:~ root# cd /Volumes
-sh: cd: /Volumes: No such file or directory
xserve:~ root#

I think you have to do it in Single User mode, or boot it into Target Mode & trash it from another Mac.

Okay what I did was create an automount to the /Volumes folder on the server which shared a mount that was on another drive, the server had ldapv3 enabled so everytime i rebooted it was mapping a share to /Volumes before /Volumes would get recreated.

I should of made the automount to /Volumes/directory

I turned off ldapv3 on server and /Volumes reappeared after rebooting
