You have something big in /var. Check /var/tmp/portage or /var/log.

Alos test sys-fs/ncdu or similar tools.

I had a similar problem, 100% cpu usage caused by a daemon that did
not respond well when network connection was lost. My
/var/log/messages grew over 60GB in a few hours with the same message
repeated tens of millions of times. I changed my logger from syslog-ng
to metalog, which suppresses duplicates, and now it's not a problem.

Well, that's the reason you should put /var on its own partition/logical 
volume.

As much as you need.

There's only one person who can determine that. That person is you.

my /var is 36gb in size.
But I also have portage and packages in /var - to keep the fragmentation of / 
down ... 
I still have more than 20gb free .... but I use reiser4+compression.

Mine is about 300MBs right now.  It has been 1GB before tho.  This is a

Hi,

I am sorry but I think if someone asks about an opinion here, writing
something like: "that's all you desision, gentoo is not taking your hand
for anything" is not helpful at all.
We all know that our systems are fit to our personal needs. So every
system is different. But asking should leed to something like: consider
this, consider that ...

And how EXACTLY do you want me to answer the original question? Be specific, 
"You should have done <blash>" responses don't help anyone. The question only 
has vague guidelines for answers and is totally install- and need-dependant.

Do keep in mind that the original is a "do my homework for me" question and my 
reply was designed to get the OP to look for himself. He didn't even post how 
big his current /var is or what his machine is used for or even which logs 
he'd like to have and keep.

Hi,

I totaly do agree with you. There has been nothing indicated to give a
one out of one answer. In case someone is a noob, ( I am still one
because I don't no anything about how everything is working) what you
just wrote is the answer. Like what are your needs and what resurces do
you have?
Like I don't think it was something like "do my homework" but more like
"I don't even know what to look for".
This list is realy helpful. I am often searching answers or learn by
reading but sometimes it is just infront of someone not even knowing it
is there.
The OP said nothing and this is what could be replyed. Like "You said
nothing".
Often googling for something is leading to lists where absolutly no help
can be found because someone writes something like: "what can I do".
secend replays like: "do A". Frst: "cool this did it for me." In the end
nobody else can use this solution because it is just not EXACT.
So you are right.

At least telling him what to look for would be useful. I for example
still have no idea, and it's after reading this thread that I checked
the size of my /var directory for the first time in 5 years.

Isn't "do A if you are in situation X , because of Z" the right pattern?

(try to avoid top-posts in this mailing list)

I think it has already been suggested:

Use logrotate to keep your logs down to a sensible size.

Also, you may want to empty ccache if you have it enabled.  ccache -C
will clear it out completely.  My /var/tmp is around 886M, half of
which is taken up by ccache at this moment in time.

HTH.

That's only if situation x is constant and absolutely known to the one
replying. But then it might not be of any use for somebody else. Most
likely there will not be a second person with the exact same situation x
around.
Also I learn a lot by following the way to the solution. Like give me
the formula and not the answer and next time I can search for everything
myself.

The original question was "how big should /var be?" and the correct answer to 
that question is "mu" (google it)

If we had the output of "df -h" and "du -sh /var/*" plus a description of what 
the machine actually does, some general advice could be given to the OP. As it 
stands with the information given, the only useful answer is "you'll have to 
work that out yourself" which is what I said right back at the beginning.

The OP might be a newbie with little or no idea of how things work in a 
mailing list like this. Instead of the "you'll have to work that out 
yourself" answer, which is a correct answer strictly speaking, but not 
very useful to the OP, one could have asked "can you provide more 
information on this and that, so people can help you better? And please, 
in the future, remember that the more information you provide, the 
better answer you are likely to get." (which, btw, is what you did 
anyway in later replies). That would be a more useful answer imho, 
because it will educate (or try to educate) the OP a little more, which 
hopefully will result in him asking questions in a better way in the 
future.

Just my 2c.

Alan's point is, there is no way for us to know that.  Example, I
sometimes use http-replicator on my machine which is placed in /var. 
Therefore, that alone could need 2 to 3GBs.  If you use ccache, then add
some more.  Also, doesn't portage use /vat to compile?  If so, then that
is some more space that would be needed.  Does the person use OOo from
source or binary?   Is this a web server of some sort?  Is it going to
be used for a DVR type system? 

A even better question would be this, how much space does the OP have to
begin with?  I have two 80GB drives.  The OP may have some huge 300GB
drive. 

I dont' have any idea what the answer to most of those are so no one
really can answer the question yet.

There's a few guidlelines one can give (but only a few). The variables tend to 
be large than the amounts with guidelines though.

/var/tmp/portage should be at least 1G on a modern system, 6G+ if building 
mozilla stuff and OOo is something you intend to do. 
portage cache is about 200M
ccache needs as much space as it was given in make.conf
/var/mail or /var/spool/mail is completely dependant on number of user and how 
much mail they get. Often none for a desktop and huge amounts for a mail 
store.
mysql and postgres need as much as the amount of data intended to be stored.
log space is very big or not too much depending on what you do.

So. The partition holding /var needs at least 1.5G on a modern gentoo system, 
probably more, sometimes LOTS more. Only the admin knows how much more and 
there is no silver bullet answer no matter how much users ask for one. 
Explaining why there is no simple bullet answer is pointless as google already 
knows where everyone else already answered that.

Years of bitter hard experience ramming my head against n00b user expectations 
has taught me never to hint at an answer - anything I say gets taken as gospel 
truth and a bunch of folk are now going to read this and interpret it as 
saying "Alan says /var must be 1.5G....". How much swap space? is another such 
question.

Perhaps a better first answer than "Only you know that" is "Only you know that 
and you need to know how to calculate it. You find that out by reading the 
fine manual."

We're in Unix land here. As such, my answers thus far are totally appropriate.

BTW: OOo 3.1 seems to raise the bar to 8.5G.

And, not to forget, one can always either resize it later (if LVM is used) or 
simply mount more space below /var, which also gives the opportunity to use 
different filesystems, depending on what kind of data is stored.

So it's getting worse... I have 6.5G free in /var and rebuilt latest OOo 
recently. My USE for OOo is pretty restrictive though - no gnome, kde, mono

IMO PORTAGE_TMPDIR should not be on such an important filesystem as /var.
Having system programs unable to function properly when they cannot write
to logfiles because you OOo emerge has filled the filesystem is not good.
A separate filesystem for this, using either ext2 or tmpfs is a safer, and
faster, option

This depends on your usage, of course, and for what purpose you expect
to use /var. If you run a server with lots of logs, like a
high-traffic web server, you may want to ensure /var/log is in a place
with enough room. I use logrotate to archive and compress log files so
they don't take up too much space. In my case I have my temp dir as
/var/tmp (i think this is the default location), so things like
ripping/encoding/burning a DVD image can use sometimes near 25G of
temp space. Portage will also use (again, as default) for its temp
dir, so any aborted compile sessions and giant packages like
OpenOffice will need sufficient space as well. KDE pixmap cache is
using 1.5G in my user's tmp directory alone. And of course portage
itself stores the packages cache there.

All of the above can be changed, of course, or links/mounted to
different drives/partitions....

I think the rule of thumb that applies is: calculate the greatest
amount of space you would ever realistically need and then double it.

I tried too but it slows down disk speed to a crawl when there's disk 
activity by an order of magnitude (commands take 3-4 seconds to execute 
while without LVM they give sub-second responses.)

Hmm, that's strange. I've never seen this and I use LVM since it first appeared 
on Linux. On Laptops, I even encrypt the logical volumes without a significant 
speed impact.

It's only there where's disk activity.  For example, if I have 4 or more 
torrents downloading.  When that happens, typing "mc" (to start midnight 
commander) needs about 4 seconds.  It's almost instant without LVM.

The speed impact on one of my servers (100+ shell users) was dramatic. 
10 seconds for a simple "ls /" for example.

It's not like LVM is modelling the universe' operation on your CPU, but
that's where impact should be, while disk activity (and data written)
should be roughly the same, aside from possible fragmentation if you
(re)create lv's on a daily basis, so prehaps it's not the disk but the
cpu where's the real bottleneck is?

I know it's not the CPU since there's 'top' to check this.

Well something creating that much messages is just buggi! The cpu will
be on havy duty no diffrence where /var is mounted. This is a bug which

My messages file gets huge sometimes too.  Usually when hal or something
doesn't unmount the DVD drive and it just spits out error after error
about every two seconds.

Let's not get started on how buggy hal is.  That could turn into a huge
thread for sure and could lead to discussions about xorg-server and the
recent upgrade.

If you unmount /home, does any file show up under /home then?  Keep in
mind, if you have files in for example /home then mount a new partition
on /home, the old files are still on the root partition.  It just mount
/home on top of the old file on the root partition.

I'm assuming the /media/* directories are CD, DVD or some other
removable media?  If not, unmount those and check to see if anything is
hiding under there.

Hope this helps.
