disk running out of space

[Naga Suresh B]

Hai,

I am facing a problem in disk space, when I say df -h on my server, it
is giving the following results:-

Filesystem Size Used Avail Capacity Mounted on
/dev/ad0s2a 9.6G 8.5G 337M 96% /
/dev/ad2s1e 55G 39G 11G 77% /data
/dev/ad0s1e 9.6G 2.0K 8.8G 0% /data2
/dev/ad0s3e 26G 1.0G 23G 4% /data3
/dev/ad0s2e 9.6G 1.9G 6.9G 22% /usr
procfs 4.0K 4.0K 0B 100% /proc

I went into / and measured all the folders it is coming around 2GB as usable
space.

What might be the problem???

Plz give me solution as early as possible.

Suresh

If I remember correctly 100% capacity doesn't mean it is actually completely full up..... I've seen it go up to about 110% prompting
me to quickly clean up the disk.....

This would probably be better on questions@ but it is possible that you
have files on the root partition under /usr that are being hidden by the
/usr partition (or any of your other partitions). Check there's nothing
`under' your mounts.

Jamie's comment about the reserved margin is also correct, but it doesn't
account for 2GB.

Thank you for your suggestion I restarted apache on my server my df -h is
giving

Filesystem Size Used Avail Capacity Mounted on

/dev/ad0s2a 9.6G 1.0G 7.8G 12% /

/dev/ad2s1e 55G 39G 11G 77% /data
/dev/ad0s1e 9.6G 2.0K 8.8G 0% /data2
/dev/ad0s3e 26G 1.0G 23G 4% /data3
/dev/ad0s2e 9.6G 1.9G 6.9G 22% /usr
procfs 4.0K 4.0K 0B 100% /proc

What might be the problem??? In future how can I overcome this type of
problems without restarting the service.

hmmmm - could possibly be your log files if there going into /var ..... could only be explained if apache is cleaning the logs on a
restart somehow.

btw, why would sending syslogd a SIGHUP help just out or curiosity?

Sounds like you moved/rotated/deleted your Apache log file but Apache
still had it open and continued logging to it. The space on disk will not
be freed until everything has closed the file. Check out the rotatelogs(8)
man page that comes with Apache for information about how to properly
rotate its logs.

"When a program is using a file, and you delete the file, the file is
not really removed from the filesystem until the program stops using
it."

SIGHUP tells syslogd to reopen logfiles, apachectl restart does the
same for apache.

It's really belongs to -questions.

Ahhh.

I love picking up the simple things after I've been using FreeBSD for about 4 years :P

oh well, here, we stop all apache around 23h45, then rotate the logs (moving them into
an other directory log/cold/<IP>/) before restarting.. It take approximately 3 seconds
to stop, move and restart.. Your users shouldn't notice the stop/start..

hope this helps..
fifi..

Buying an operating system without source is like buying
a self-assembly Space Shuttle with no instructions.

That's what newsyslog is for, and you don't have to stop apache:
/path/to/httpd-access.log 640 7 * $W0D0 B /var/run/httpd.pid 30

Yep, and there's also the rotatelogs(8) utility that comes with apache,
e.g. to rotate once a week:

CustomLog "| rotatelogs /path/to/log/fileprefix 604800" combined
