Re: Auto-resize partition when create VM
Fariborz Not sure if it is clear from your emails or not but the disk size you are selecting in the add instance wizard is not the root disk size, instead it is the size of an extra disk that will be available and attached to your instance. Hopefully Nux's emails make more sense to you now. > On Nov 21, 2013, at 4:05 AM, Fariborz Navidan wrote: > > Hi. > Can I write down the above into a shell script and add it to first boot? > Can I then resize the root volume? > > >> On Thu, Nov 21, 2013 at 3:22 PM, Nux! wrote: >> >>> On 21.11.2013 11:30, Fariborz Navidan wrote: >>> >>> If I use LVM on template, can I add a script that resizes the root logical >>> volume (LV) via LVM on the first boot?

Yes, those commands will extend your root LVM over to the new DATA disk that you added. However, you must only run that ONCE, running it at every boot will likely wipe out the data from it and re-add it to the LVM so be careful. Another gotcha is that if you add yet another DATA disk, it will be called /dev/vdc or /dev/vdd and so on, you will need to add some extra logic into your scripts to make sure you will not lose any data. -- Sent from the Delta quadrant using Borg technology!

If you user LVM inside the template, then once you add another disk (if you're on KVM it's going to be called "/dev/vdb") you can just do: - pvcreate /dev/vdb - vgextend ExistingVolumeGrop /dev/vdb - lvextend -l +100%FREE /dev/ExistingVolumeGrop/VolumeName - resize2fs /dev/ExistingVolumeGrop/VolumeName All the above can be run live, no reboot required (if you use ext4). -- Sent from the Delta quadrant using Borg technology!

Re: Auto-resize partition when create VM
If I use LVM on template, can I add a script that resizes the root logical volume (LV) via LVM on the first boot? Then how to get the allocated disk size from cloudstack? Regards.

Auto-resize partition when create VM
Hi. When a new VM from template is created the main partition is not resized to the sized defined in disk offering. So the volume has space but not usable. How make it resize automatically when a VM is created? Regards.
