Help Requested: System Disk 100% Full

Post by Cine-Me » Sun, 28 May 1995 04:00:00

How does one handle the /dev/root 100% full message?  I can't seem to find
any info on how to handle this... Can't even access this file: don't know

Any advice/help is much appreciated, and thanks much in advance.

/dev/root is just one form of the name for your root filesystem
(probably holds everything on your system that is not in your /usr file

The way to handle the message is to find files that should not be in the
root filesystem, and either delete them or move them somewhere else or
compress them.

One of the first things to look for is coredumps: try

$ find / -name core -print | xargs ls -ld

You can use the 'file' command on any particular coredump to figure out
what is dumping core. Once you know -why- it is dumping core (or
do not care), you can remove the 'core' files.

If your system has PANIC'd recently, look first for a crashdump in
/var/adm/crash . If you find something there, you may be able to use one
of the 'crpt' (core report) scripts to find out what caused the crash --
though a summary should have been placed in your /usr/adm/SYSLOG .

Look also for files in /tmp and /var/tmp that are no longer needed, and
remove them. You can find out whether a file is currently in use by
using the  /etc/fuser  command on the file. If it gives any process number,
some process currently has the file open.

Lastly, you should use 'versions' to review the software you have
installed. If there is anything you do not need, you can use 'versions remove'
to get rid of it. For example,   versions remove
will probably get back quite a bit of disk space.


1. Help swapping 1.2GB system disk w/ 2GB system disk

First some background:
- The system is an Indigo R4400 running IRIX 5.3
- There are currently two (2) 1.2GB Hard disks
- The filesystems are arranged as follows (/etc/fstab)
        o    /dev/root / efs rw,raw=/dev/rroot 0 0
        o    /dev/dsk/lv0 /usr efs rw,raw=/dev/dsk/lv0,fsck 0 0
- The logical volume information is as follows (/etc/lvtab)
        o    lv0:/usr logical volume:devs=/dev/dsk/dks0d1s6,/dev/dsk/dks0d2s7

Now my problem:
The system boot disk is starting to experience media errors and I can
no longer map out bad blocks.  However, the system is currently stable
and I need to do something before the system crashes.

I have a new 2GB Seagate Barracuda SCSI disk that I would like to swap in
in place of the system disk, but I do not no where/how to begin to do

This seems like a simple enough task, but I do not want to mess it up
with my ignorance.

Can anyone step me through this process?

Thanks in advance.
