[pve-devel] Error between PVE and LVM

[Alexandre DERUMIER]

Hi,

>>In previous versions of PVE, this task was possible do it with much easily. 

We have made no change since resize feature has been implemented.
Can you describe a little bit more the problem on the guest side ?
do you see disk size increase with parted/fdisk ?



Do you use raw lvm disk in your vms ? or partitions on top of lvm ?


I have add a customer during a previous training session, which have problem with raw lvm disk in vms,

because of proxmox host scanning all lvm disks on the host side. (Don't remember if it's have impact on resize).

We have need to add a filter in lvm.conf on the host, to exclude scan of vms lvm disk.

Objet: [pve-devel] Error between PVE and LVM 

Hi to the PVE team. 

I found a problem between PVE and LVM. 

Considering that if it is used LVM as block device for the virtual disks of 
the VMs, Linux give us a great comfort, but the problem is that if I in 
"online mode" enlarge a Physical Volume and after enlarge a Logical Volume 
by CLI, in PVE, the VM can not see the new free hard disk space without 
partition. 

In previous versions of PVE, this task was possible do it with much easily. 

Moreover, i think that this feature is very util, due to that in the actual 
condition, it force me to power off the VM and start it again, so that being 
a server (talking about of the VM) that is in a production environment, only 
can I do it outside of working hours. 

So i would like to ask if the PVE team have interest in correcting this 
problem. 

Best regards 
Cesar
