Filesystem Capacity Reached! Alternative Solutions?

[Patrick Kajirian]

Hi everyone!

Here's the problem. Several PLESK system directories were installed on a filesystem with low-capacity space. The filesystem is quickly reaching max capacity. Is there any way to re-distribute the system directories onto filesystems with a higher capacity?

Ideally I want to re-allocate the bulk of the directories from /dev/sda5 to /dev/sda2. See the Hard Disk Usage chart below:

____________________________________________________________________________

Filesystem Total Used Available Capacity
========== ============= =========== ============= =========

/dev/sda2 218 921.67 MB 8 775.15 MB 198 846.50 MB 4.01%

Protected directories /usr/local/psa

/dev/sda5 4 065.09 MB 3 211.33 MB 643.93 MB 79%

Protected directories /var/lib/mysql
/var/www/vhosts
/var/qmail/mailnames
/var/named/run-root

proc 0.00 MB 0.00 MB 0.00 MB 0%

sysfs 0.00 MB 0.00 MB 0.00 MB 0%

devpts 0.00 MB 0.00 MB 0.00 MB 0%

/dev/sda1 189.88 MB 12.14 MB 167.94 MB 6.39%

tmpfs 1 960.52 MB 0.00 MB 1 960.52 MB 0%

none 0.00 MB 0.00 MB 0.00 MB 0%

sunrpc 0.00 MB 0.00 MB 0.00 MB 0%

Can anyone suggest ways of accomplishing or remedying this situation with the least ammount of downtime?

Much appreciated!

In such a situation, I make room by moving the big directories on a disk/partition where there is free space, than I replace the directory by a symbolic link to the new location, so this is fully transparent to the system.

Make sure to shut down any service that may be accessing the directory before operating, or you may get into trouble.
