1&1 RootServer var-partition full

[HMnet]

Hi @all,

I have a little problem with my 1&1 rootserver:

The partition that cointais i.e. mails and mysql /var is nearly full.

Filesystem Size Used Avail Use% Mounted on
/dev/sda1 940M 108M 785M 13% /
tmpfs 990M 0 990M 0% /dev/shm
/dev/sda5 4.7G 1.7G 3.1G 35% /usr
/dev/sda6 4.7G 4.3G 419M 92% /var
/dev/sda7 19G 424K 19G 1% /home
/dev/sda8 156G 57G 100G 37% /srv
none 990M 36K 990M 1% /tmp

Last night anyone sent a huge mail and the space of /var ran aginst zero, so the server dies. :-(

Now I have to solve the problem.

Can I symlink the maildir like this:
ln -s /srv/mailnames /var/qmail/mailnames

THX for your help,
HMnet

Same for me on Suse !

Seems like /var isn't mounted on the right partition only 4.7 Go, argh !!

How can we solve this?

Thanks,

Hi!

I solved the problem with symlinks.

I moved these directorys to /srv an the I made symlinks from the original directories to it:

/var/lib/psa/dumps
/var/log
/usr/local/psa/var/log
/var/qmail/mailnames

So my var-partition has 3,3GB free.

Yours,

If this helps at all, Ive got a script that will re-image a 1and1 box with centos4 or 5, and redo the partitioning layout to /boot, / and swap here:

hi,

why not move the affected folders (mysql databases, mail dir, ...) to a bigger partition?

 

[jchatard]

That sounds great, but how can I do this without unmounting my partitions ?

I can't turn off any websites I'm hosting...

Any advice?

You don't have to umount something.

In case of mysql you only have to
- stop the mysqld
- create a new folder for all your mysql databases, e.g. /srv/bigplace/mysql
- move all subfolders of /var/lib/mysql/ to that new location (you'll see: folder names = db names)
- edit mysql config file /etc/my.cnf (in the [mysqld] section add a line "datadir=/srv/bigplace/mysql")
- if you are using InnoDB, you have to set innodb_data_home_dir too, normally not necessary
- start mysqld

This takes 3 minutes + time of moving the folders and files.

Similar you have to do that with other services.
