Do you have the mdisk device number specified with (ro) after it in your kernel parms? This is necessary, as well as having it read-only in the CP directory for the guest. (That makes a total of 3 different places it needs to be specified.)
Is the "owning" Linux guest up and running? If so, that's a no-no. That means the file system is dirty, and not consistent to the other guests sharing the file system. More than likely your system is trying to replay the journal, and failing, due to the read-only status. Since having the owning system up and running is a no-no, using any of the journaling file systems is pretty pointless. You use journaling file systems so that if a system crashes for whatever reason, the file systems that are mounted read-write can be recovered quickly using the journal. File systems that are mounted read-only by definition are in a consistent state, so no journals are needed. I would recommend using ext2 in all these cases. Just remember that any and _all_ systems that have the file system mounted must have it read-only.

I am linking to a good install of SuSE SLES8 (which is in a linux guest) from another linux guest. I am linking readonly to the MDISKs that holds /usr /usr/src and /opt. I am mounting in /etc/fstab as RO for these 3 filesystems The /usr and /opt are behaving and seem to be working. The /usr/src is not working. Spitting out lots of ugly sense codes... I removed the /usr/src entry from the fstab and I can come up. Then I tried mounting the /usr/src and got ugly msgs, but it did mount and I was able to get into the filesystem...although it spit out those ugly msgs every time ;o) What am I doing wrong ?? How can I fix it??
