  • Subject changed from resize root disk on osd to update osd VM root disk VM config and resize root disk on osd

today I conducted maintenance on osd disks with gschlotter as he informed me some days ago that the configuration for the disk in libvirt should be updated from

<disk type='file' device='disk'>
<driver name='qemu' type='raw' cache='none'/>
<source file='/dev/mapper/3600a098054344a77432b4550736e7850'/>
<backingStore/>
<target dev='vdd' bus='virtio'/>
<alias name='virtio-disk3'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/>
</disk>

to

<disk type='block' device='disk'>
<driver name='qemu' type='raw' cache='none'/>
<source dev='/dev/disk/by-id/dm-uuid-mpath-3600a098051764a2d345d436b4a445669'/>
<backingStore/>
<target dev='vdc' bus='virtio'/>
<alias name='virtio-disk2'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
</disk>

On 2020-12-10 he conducted the change while osd VM was powered down and we confirmed that the machine booted up correctly afterwards, e.g. no disk identifiers changed.

While we were at it we also resized the root disk from 10GB to 20GB.
