I have a fairly serious problem, which I can't seem to correct. I have
four cubes, of which they are getting along pretty well, until yesterday.
On one of the machines (all with hard drives), I wanted to create an
entry in the fstab (netinfo fstab) for the optical drive, so I did.
For one reason or another, I changed my mind, and took it out of the
database using NetInfo, along with another mount that was obsolete. The
only problem is, that after I rebooted the machine, it no longer wants
to mount anything, even it's own disk. Hence, df returns with just the
headers, /etc/mtab is empty, etc.
All the other machines still appear normal, mounting and unmounting at will,
including the "dead" machine's filespace. Note that while /dev/sd0a is not
mounted, the machine still finds all the local filespace with no problem.
This is obviously a major problem, but I'm not even sure where to explore
next to try to find an answer.

The same style procedures will typically hold true for similar problems -gerrit] First, you need to verify if the fstab "directory" still exists in NetInfo. Try the following: % niutil -list . / 1 machines 3 users 16 services 63 printers 84 mounts 100 groups 351 networks 1931 protocols 1942 rpcs (All of the following commands will need to be done as "root"). The important one here for your situation is the "mounts" entry. The corresponding number (84 in this case) is not important to what you are doing. If the "mounts" entry exists, you can skip the next step. Otherwise, you can create it via the following: # niutil -create . /mounts Now you have a place to store the mount information. Next, put the following lines in your /etc/fstab file (you may need to be root to edit this file): /dev/sd0a / 4.3 rw,noquota,noauto 0 1 #/dev/od0a / 4.3 rw,noquota,noauto 0 1 The second line is currently commented out. If you ever want the OD to be permanently mounted, remove the "#" character from the front of the second line. Make sure that there aren't two lines which try to mount /dev/sd0a - either NetInfo or Unix might get confused if there are (I've never tried confusing it that way - it might be more robust than I'd bet on.) Now, tell NetInfo about this information using: # niload fstab . < /etc/fstab Then, to finish things up, you should try the following # mount -a Then, to check up on things, try: # df If this doesn't work, send me a note letting me know what broke and where, and I'll see if I can dream up something better.

I tried this procedure again, but still with nothing in my /etc/mtab.
