Proxmox I installed on my server with 2 physical disks mirrored RAID1 (with a hard raid controller PERC) seen as / dev / sda with a size of 73GB for Linux.
Proxmox partitionnment installed with a default I had in the end the following partitionnment download:
calc0: / var / lib / vz # fdisk / dev / sda-l

What makes it not much I had to create my virtual machines for OpenVZ a simple df told me that I only had little more than 19GB free: calc0nokvm: / var / lib / vz # df-hT

It turns out that I had added three brand new 400GB drives in RAID5 so that I had a / dev / sdb 800GB of wondering who to be used. I unable to format is to use a symbolic link to link / var / lib / vz / root partition to my new seuleument of the tremendous blow web management interface Proxmox would not have given correct information on the available space, so I ' I decided to use the great opportunity to LVM2 Logical Volume Manager for Linux.

- Increasing the size of a logical volume, in this case I add 100GB to volume / dev / pve / data
calc0nokvm: / var / lib / vz # lvextend-L 100 G / dev / PvE / data
calc0nokvm: / var / lib / vz #
Extending logical volume data to 140.00 GB Logical volume data
Successfully resized
not forget to update the filesystem with resize2fs-p / dev / pve / data - resize2fs 1.40-WIP (14-Nov-2006) Filesystem at / dev / pve / SI data mounted on / var / lib / vz; on-line resizing required old
desc_blocks = 3 = 9 new_desc_blocks Performing an on-line resize of / dev / pve / data to 36701184 (4k) blocks. The filesystem on / dev / pve / data Is Now 36701184 blocks long. calc0nokvm: / var / lib / vz # df-hT

Now as you can see from the above, I df well and truly won over 100GB on my pve-data logical volume or is "mount" my / var / lib / vz. And all without service interruption. I can any time restart the command to add space on one of my logical volumes. This flexibility is not beautiful? "
