I have :

1 primary ext2 boot
2 primary linux-swap
3 primary ext3

Part 3 has : 64.4GB 85.9GB 21.5GB Free Space

They are mounted like this:

/dev/sda3 on / type ext3 (rw,usrquota)
/dev/sda1 on /boot type ext2 (rw)

I got 21,5 Gbyte unallocated free space from my hoster on the VPS. I would like to add this extra space to partition 3 ( "/" ). I know I can do this using live cd but that's not what I want to do, because I'm not physically at the sever-site. Another way is to un-mount the partition, and then resize using parted. That's what I like to do.

Can I unmount the / partition without harming Cpanel. What services do I have to stop. Or what other ways of achieving this partition resizing do you recommend?

thank you.

Hello :)

You mentioned this is a VPS. It's likely better that the additional space is allotted to your primary partition by your VPS provider. It's not recommended to attempt to manually modify your partition without physical access to the server, and it's possible that your VPS software does not allow individual VPS owners to make such a modification.

Thank you.
