Filesystems, Disks and Memory

Hi, I am new to the UNIX operating system and would realy appreciate some answers to these problems.

I have a unix box (Actually several of them throughout the different locations) that have NCR MP-RAS 3.02.x.x (with multiuser and possibly security packages installed.)

Originally they had 2gb HD (seagate) old 50pin-SCSI 1 - other techs before i came to the company had modified the config of the box to 35gb seagate
SCSI 68pin UltraWide.

This config is ok - BUT i am running out of disk space because the sizes of the partitions are the original size that was setup from NCR or whoever.




When i log in as root this is the login screenshot :

you have mail




Screenshot of when i do a DF command :


/ (/dev/root ): 155478 blocks 35999 files
/proc (/proc ): 0 blocks 135 files

Can anyone help me with my Stupid dilema ???
Any help is really appreciated.
Thanks.

Hi Guys,

i would really appreciate some help, if anyone has any ideas,
please post them.

Thanks.

Anyone ???

Semi-short answer:
You need to reinstall. The disk partition in which your MP-RAS image
resides in, is too small to add any -additional- filesystems and there
are no tools to dynamically grow your VxFS filesystems. Moreover,
the version of MP-RAS you're using doesn't "see" other disk partitions
on the -same- disk (so you can't just create other disk partitions on
the 35G disk and add new filesystems there). If you can't re-install
for some reason (lost CD or license diskettes), you can add a new
drive to the system and MP-RAS will recognized the new drive (once
you reboot (or run ``mktable''), then use ``sysadm'' to create new
filesystems.

Comments:
I'm not aware of any NCR (or Teradata) sponsored installation that
would appear this way. If I were to guess, the 2G drive(s) died and
the next smallest drives available were 35G so those were used.
Notably, you're missing ``/var'', ``/opt'', and ``/usr'' which are fairly
standard on all NCR UNIX (MP-RAS) installations.

The following message is particularly broken (but fixed in much later
versions of MP-RAS) and output by the ``dfspace'' command:

...
Total Disk Space: 84.45 MB of 912.39 MB available ( 9.26%).

MP-RAS (until recently) assumed it owned the entire disk whenever
it was installed, and to that end, was installed in so-called "no-compat"
mode. Thus, it only "knows" about the drive to the extent of the disk
partition it which it resides (was installed) in.

hi cer,

thanks for your ideas...i really appreciate it.

Its funny we found the originally software install cds in back closet when we were cleaning - we though they were lost.

NCR had told me that it is very complicated to do an original install of the system from scratch since it has so many patches for security and all the applications involved to run the whole system.

Anyway we contacted NCR to see if they could help with the disk partitioning of the 35gb drive and it seems we were able to add disk slice/s (partitions) to the drive - but it is not fully tested in that particulay config.

Once again,
thanks for the help.
