/var FS full. What can be erased?
|
|
|
I've already deleted all /var/tmp and checked /var/log file sizes. The
logs are very small. Btw, what's the correct way to clean log files? As
far as I know it cannot be just deleted. Right ?
Here is what "df -h" shows:
srv002# df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/da0s1a 248M 101M 127M 44% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/da0s1e 248M 24K 228M 0% /tmp
/dev/da0s1f 30G 1.6G 26G 6% /usr
/dev/da0s1d 248M 232M -4.5M 102% /var
devfs 1.0K 1.0K 0B 100% /var/named/dev
What else can be deleted ? Please help.
Kind regards,

freebsd rotates logfiles as needed, see newsyslog
What else is in your /var/? Maybe some mysql databases?
in /var/ do a
# du -hs *
so you can see what directory holds the data.

Do you know what is taking up the space? What do you get if you cd to
/var and type du, or do
du | sort -n +0 |

After replacing Vlad Mfk with a small shell script on Wednesday 19 Jul
2006 20:19, the following appeared on stdout:

cd /var && du -h . | less (the dot is literal, not a part of my post's
punctuation). Look through the output to see where the largest use of
the filesystem is. Don't touch /var/db/pkg if you can help it; your
pkgtools rely on information in that directory.

This is where email and print jobs are stored until either
a user reads her email or the print job is sent to the
printer. I'm guessing that you haven't rerouted root's
email to someone who actually reads email. See /etc/aliases.

Why would he have two devfs on his system? one I know that's mounted
under /dev is correct, but what's this /var/named/dev ?
maybe an extra line that's not needed in /etc/fstab? I don't know, I
want to know!

BIND now runs chrooted as standard, so it needs its own devfs
mountpoint. If you have a look at /etc/namedb, you will find it is now
a symlink to /var/named/etc/namedb.

If you read the mysql directions you can use variable to put
the data anywhere you wish. Since you have the most free room
on /usr, you could put the data in a directory on that filesystem.
Your 'spool' directory is quite large. Check under that to see
what sub-directory is using the most room. It may be some mail
that is stuck or generating a lot of messages.

off-topic but a small hint concerning filesystem layout.
I think your system's filesystems like /, /tmp and /var
are too small.
I see that you have diskspace but only create a relatively
huge /usr.
/tmp could also be a memory filesystem, feeded by swap space,
this helps not wasting even more space for /tmp. so you can make
swap reasonable big for big processes eating up much memory
and at the same time use it for /tmp, so that the swap is not
"totally lost" but of good use for /tmp ;-)
Another thing I see is, that /usr is quite big.
Imagine, some of your bsd system's files got toast somehow and
you want to restore /usr to sanitize your OS.
If /usr is that big and mixed with files of your users and
files of the ports collection /usr/local,
well then I think it might last a very long time to restore.
Another thing is, that I personally do not want to have
big file movements on system partitions.
If you have heavy I/O and file creation and deletion on /usr
and the system crashes, then I have personally a better feeling,
if I know that there was not much traffic on system partitions
needed to boot and run my Unix installation, so that its very very
unlikely, that the superblock gets into inconsistent state.
Usually he doesnt do but then you have an extra safety belt.
Therefore many people prefer having a small root "/" and
partition the filesystems.
I also prefer to have a reasonable /usr.
Look here an excerpt of my partitioning on 2 discs:
Filesystem Size Used Avail Capacity Mounted on
/dev/ad6s1a 989M 55M 855M 6% /
/dev/ad6s3d 3.9G 1.8G 1.8G 49% /var
/dev/ad6s1d 3.9G 1.6G 2.0G 44% /usr
/dev/ad6s3e 3.9G 832M 2.7G 23% /usr/X11R6
/dev/ad6s3f 5.8G 2.8G 2.5G 53% /usr/local
/dev/ad6s3g 24G 14G 7.8G 65% /home
/dev/ad4s3d 52G 42G 5.1G 89% /data
/dev/ad6s3h 38G 8.0K 35G 0% /export
procfs 4.0K 4.0K 0B 100% /proc
linprocfs 4.0K 4.0K 0B 100% /usr/compat/linux/proc
/dev/md0 496M 214K 456M 0% /tmp
devfs 1.0K 1.0K 0B 100% /dev
devfs 1.0K 1.0K 0B 100% /var/named/dev
to make /usr independend of ports collection I give me the
luxury of having separate filesystems for /usr/local and /usr/X11R6.
I could have used another hierarchy for ports collection than
/usr/.... but ... I feared to stumble over ports that might not
be prefix clean. Therefore this personal tradeoff.
