What to clean on a Zimbra mail server?

[tezarin]

Hi all,

Hope this is the right place to post this question. Today I ran the df -h command on my mail server box and the result was showing that the root directory is 65% full.

Then i looked for large files and looks like the size of /var/spool/clientmqueue is 58G.

Since the root directory has been filling up almost 1% per day, I was wondering what files/directories I can delete to empty up the space on this server.

I will appreciate your help

The Zimbra files are all stored in the /opt/zimbra directory structure, you don't (you shouldn't) have that on your root filesystem do you?

For further information on that directory take a look at some of these answers: +"/var/spool/clientmqueue" +rhel - Yahoo! Search Results

Hi phoenix,

You're right, they are stored there. What I was trying to say was the df -h command on my mail server box returns 65% and it's increasing everyday:

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                      901G  552G  303G  65% /
/dev/sda1              99M   33M   62M  35% /boot
tmpfs                 3.9G     0  3.9G   0% /dev/shm

Can I do something to clean it up? i.e. Removing the content of /var/spool/clientmqueue or something?

Thanks

I've given you the answer to that question in the link in my previous post.

Thanks phoenix,

I did some research before posting here and have seen some posts which advise me to just remove the content of that directory, i.e. https://forums.oracle.com/forums/thr...sageID=8456547
but is it safe? Would this be something that can be done on a *ZImbra* mail server?

There should be no reason why you can't remove then on a Zimbra server, as I've already mentioned the zcs files are all in /opt/zimbra. I suppose the question you need to answer is 'why is that directory so large'.

Thank you Bill, appreciate your help.

I haven't installed anything on that box, I inherited it from the previous person who was in charge of the box. Have been monitoring the size of that directory and have been noticing the size of that directory has been increasing.

To me it looks like the mails are being sent internally, as I opened one of the files inside that directory and ths is what the content looks like:

I'm really being careful not to break anything that's why am acting a bit to causios when it comes to deleting the content of that directory... Can I please ask you what I should expect to have in that directory or it has to be empty?

I believe those are messages from crontab and that would appear to be the case with the information in your output. Take a look at this thread and particularly the second post for details on what's causing it, details on how to remove the folder contents and a link to a method of stopping them.

Thanks! What a coincidence, I was just following the steps recommended in that link...

OK, now I have removed the content of that directory and am down to 58%. The /home/backup/zimbra seems to be full, too. Especially a directory called store. Should I delete the content of this directory, too? Thank you in advance

What is the content of your /home/backup/zimbra? Is this Zimbra backup folder or one of your Zimbra data volume?

store folder usually used by Zimbra mailbox, I strongly advise you to look further the folder before trying to delete store folder to avoids human error on data deletion .
