Disculpa si no me explique bien, tengo una VM a la que quiero aumentarle el tamaño, es decir al crearla de di 20GB y ahora quiero aumentarla a 40 GB, lo primero que hice fue aumentar el tamaño en la opción que te da proxmox(no quiero agregar otro disco), a máquinas virtuales con W$ solo tengo que agregarle la partición o aumentar la que necesitaba aumentar pero con máquinas virtuales un Linux es un poco más complicada la cosa he probado con resize2fs pero la partición que debo aumentar es sda1 que tiene montada la raíz /. Sigo investigando y probando si encuentro la solución la publico, @Pablo Pinet gracias por la respuesta estoy usando proxmox 3.2, uso proxmox desde la versión 1.7 y es la primera vez que necesito aumentar el tamaño del disco de una máquina virtual con Linux sin la opción de agregarle otro disco, sucede que esa máquina virtual es una que estoy migrando desde vmware para proxmox usando qemu-img para convertirlo en raw porque es una de las primeras condiciones que pone proxmox para aumentarle el tamaño http://pve.proxmox.com/wiki/Resizing_disks

Responderé lo que creo que entendí: Leí que necesitabas aumentarle el disco a una VM??... sin embargo el procedimiento es para aumentar el tamaño de las particiones de Proxmox... (nada que ver con las VM. Si es lo primero... desde la interfaz web se puede aumentar el tamaño de los discos, incluso poner mas de uno. Si es lo segundo... aqui tienes una guía del sitio oficial re-buena....

The existing hard disk is *sda* generally, if the SATA slot it is on is numbered lower than the new one is on. Legacy IDE hard disks may be *hda, hdb*, etc. Check that the new hard disk is recognized with: *dmesg | grep "] Attached SCSI disk"* sd 1:0:0:0: [sdb] Attached SCSI disk sd 0:0:0:0: [sda] Attached SCSI disk or with: *dmesg | grep "[h,s]d[a,b]" | grep " logical blocks: "* sd 0:0:0:0: [sda] 3907029168 512-byte logical blocks: (2.00 TB/1.81 TiB) sd 1:0:0:0: [sdb] 3907029168 512-byte logical blocks: (2.00 TB/1.81 TiB) Prepare the new Hard Disk fdisk /dev/sdb : Pass 1 *fdisk /dev/sdb* The number of cylindersfor this disk isset to 13953675.
