Unhappy How to free up space on a Linux Red Hat Server running Kerio Mail Server


Good morning and hello,

I'm posting this blog in hopes to remedie a problem I'm having with Linux Red Hat and running Kerio Mail Server 6.5.2 on it.

In the past week, our mail server is running alot slower (sending and receiving) email.

My question is this. I'm new to the Luinx world and was wondering if there is some type of cached memory or a swap file that needs to be deleted on the server.

Afer running the command on the server Df-h, I get the following information.

/dev/mapper/VolGroup00-LogVol00

Size Used Avail Used

266G 87G 166G 35% /
/dev/sda2 99M 99M 0 100% /boot
none 1013M 0 1013M 0% /dev/shm


As you can see, the boot drive is full @ 100%. I'm assuming once the drive is full, its starts to cache to another drive or volume??

Is there some type of log / temp file that needs deleted on the server.


Please help! .. thanks, Jeff

Can you show us the top output?
/boot is normally for storing kernel in, but it shouldn't be 100% full though.

It could be if they're not removing old kernels when they run updates.

It's not necessary to post the same thing twice (and it makes the thread confusing). Your first post in the thread was sufficient.

Post the results of:
$ rpm -qa | grep kernel

and

$ uname -sr

You can probably remove unused kernels unless you have a reason not to. Be aware that freeing up /boot space may not necessarily fix your problem.

Indeed, that top shows that the system load and cpu nums are tiny, and almost no swap being used. Should be running fine..
I could hazard some guesses, but really need a mail expert (I think).
