Change size of /Var mount using command line

[Keith Jordan]

I have a 100GB disc and my /Var folder is only set to use 4GB and I need to increase this. I have tried using the command lvextend -L +10G /dev/mapper/vg00-var to try to increase the size allocated to the parition Var but when I run the df command again to see if the size has changed (after restarting the server) it does not change.

Does anybody know how I go about changing the size of the Var partition? Any help would be much appreciated.

Use command

lvextend -L +3G /dev/vg00/var

instead

lvextend -L +10G /dev/mapper/vg00-var

Thank you for your suggestion, Igor. However, it has not made any difference to the size of the partition. Is there something that has to be done in order to make the system recognise the new size of the partition?

I am very new to Linux command line as you can tell! Any hele would be much appreciated.

Anybody else got any ideas on how to increase the partition size of VAR??

My webs host gave me the links below to resolve this problem which I shall try at the weekend I think. I shall let you know how I get on. I thought I would share this here in case anyone else has this same issue.


The following FAQ below will be of help in increasing the hard drive space for your servers partitions.

How do I assign additional disk space on a Linux DCS?

What if my physical volume size has not changed after increasing disk space?
