Re: [CentOS] enlarging partition and its filesystem

Hi Fred, That would depend on what the underlying device is using. Do you know if you are using LVM or not?

Type `lvdisplay` at the console to display any logical volumes. If you are using LVM, you should see one named something like 'VolGroup00_lv-root' If this is the case, something like this should help, but I have listed out the steps below for the TL;DR version: https://wiki.centos.org/TipsAndTricks/ExpandLV

*pvcreate /dev/xvdb* (xvdb is the Xen version, you may see sdb or some other combination.) *vgextend VolGroup00 /dev/xvdb* (Where VolGroup00 is the Volume Group you found before) *lvextend -l +100%FREE /dev/VolGroup00/lv-root* (Or where ever the LVM device is created. lvdisplay will show you this.)

Then simply: *resize2fs /dev/VolGroup00/lv-root* to expand the filesystem on the new block device.

Hope that helps.

Cheers, Ian

Hi all!

I've got a VM at work running C6 on HyperV (no, its not my fault, that's what the company uses. I'd rather gag myself than own one of th ose things.)

I ran out of disk space in the VM, so the admin enlarged the virtual disk. but now I realize I don't know how to enlarge the partition and its filesystem.

I'll be googling, but in case I miss it, it'd be great if someone could point me in the right direction.

thanks!

Fred
