/dev/shm Problem

[groups@…]

I'm running Mondo 2.2.0-2 on a modded RH linux 9 box (2.6.17.13 kernel)

For some reason, mondo mounts /dev/shm to a tmp.mondo.[0-9] directory at only 350 megs.

...ran just fine. :-)

df confirms, /dev/shm is mounted at 350 megs and is full. I've seen several posts about this on sourceforge, but know one seems to have a solution.

Any ideas?

The box has 2G of ram.

fstab contains:

none                    /dev/shm                tmpfs   noexec,nosuid
 0 0

mount verifies it is mounted and rw:

none on /dev/shm type tmpfs (rw,noexec,nosuid)

df says:

none                 1015M     0 1015M   0% /dev/shm

True. I think it was usedd at a time where machine did not have that
amount of memory they have now.

You could try to remove it from fstab, that way mondo won't use it.
Slower but safer. Workaround only, I added a trac entry #102 to solve it
more efficiently in future.

The solution was already posted in the devel group.  It requires
logging in via another shell and remount /dev/shm to a much large size
(in my case 3gig).

Perhaps mondorescue could have an option to set the  /dev/shm size?
Or maybe it does and I missed it.
