Updatedb Taking Too Long

Hi list

For some reason mlocate is taking a long time when I run the updatedb command. Have a look!

[root@beta:~] #time updatedb real 19m48.729s user 0m0.400s sys 0m2.728s

It’s not a big volume by any means

[root@beta:~] #df -h Filesystem Size Used Avail Use% Mounted on
/dev/xvda1 75G 9.1G 63G 13% /

So I’m wondering what could be causing this command to take so long.

I’m running CentOS 5.8 in a xen vm.

I was hoping I could get some advice that would help me troubleshoot this problem.

Thanks!
Tim

One thought on - Updatedb Taking Too Long

  • Does

    # time /etc/cron.daily/mlocate.cron

    take the same amount of time? It calls updatedb with a list of file systems to be skipped.

    When updatedb is running, get the PID of the process, and try to follow the files the process has opened by:

    # ls -l /proc/PID/fd

    Do this now and then when updatedb runs this might give you an idea where in the file system it spends most of the time.
