Description

When I try to resize (increase) disk on running VM through Sunstone, I get error:
[one.vm.diskresize] New disk size has to be greater than current one
Both for persistent and nonpersitent disks on Ceph backend.

In oned.log there's same error:
Fri Jan 19 16:26:32 2018 [Z0][ReM][D]: Req:2080 UID:0 one.vm.diskresize invoked , 3030, 0, "0"
Fri Jan 19 16:26:32 2018 [Z0][ReM][E]: Req:2080 UID:0 one.vm.diskresize result FAILURE [one.vm.diskresize] New disk size has to be greater than current one

Setting larger disk size on VM creation works however.

Expected Behavior

Able to resize disk on running VM

Actual Behavior

I get error "New disk size has to be greater than current one"

Hi, affects to me too, after updating from 5.4.1 to 5.4.5.

[kvaps]

works for me via command line:

onevm disk-resize 5891 0 20480

[Madko]

same here with 5.4.6

[sergiojvg]

Same for me. OpenNebula 5.4.6 compiled from source

@kvaps while this command shows disk resize done but inside VM we find only 2TB of disk size. I am using OpenNebula 5.6.1. Is there any issues?

[kvaps]

OpenNebula 5.6 have no this issue, try check your drive via qemu-img info maybe you need to resize partitions manually there.
