upengan78,

You still have a lot of unused disk space.

You have two PV's combined space of "201.96 GB" in a VG called "system" and you have free 145.96 GB. You can try this command to extend the reiser without unmounting.

#lvextend -L+7G /dev/system/var_lv
#resize_reiserfs -s+7G -f /dev/system/var_lv

Note that the command set to 7 GB to /var as /var already has 3 GB(10GB that you want to allocate right?). Or if you want to make it bigger.

Cheers!
