fwiw, remounting a UFS file system from r/w to r/o is not implemented, check remountfs() > You could try to write-lock it using "lockfs -fw /", > but I'm not sure that's well-advised. I vaguely remember that this is not a particular good idea for "/", this can trigger all sorts of hangs because the devfs code may call into UFS to get and set file attributes, because of the write lock it'll be blocked, other activities may depend on it and the system may eventually wedge. --- frankB This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list [email protected]
