Michal Privoznik b0579ed900 storage: resize vol against real allocated size ... Currently, 'vol-resize --allocate' allocates new space at the vol->capacity offset. But the vol->capacity is not necessarily the same as vol->allocation. For instance:. [root@localhost ~]# virsh vol-list --pool tmp-pool --details Name Path Type Capacity Allocation ------------------------------------------------------------- tmp-vol /root/tmp-pool/tmp-vol file 1.00 GiB 1.00 GiB [root@localhost ~]# virsh vol-resize tmp-vol --pool tmp-pool 2G [root@localhost ~]# virsh vol-list --pool tmp-pool --details Name Path Type Capacity Allocation ------------------------------------------------------------- tmp-vol /root/tmp-pool/tmp-vol file 2.00 GiB 1.00 GiB So, if we want to allocate more bytes, so the file is say 3G big, the real allocated size is 2G actually: [root@localhost ~]# virsh vol-resize tmp-vol --pool tmp-pool 3G --allocate [root@localhost ~]# virsh vol-list --pool tmp-pool --details Name Path Type Capacity Allocation ------------------------------------------------------------- tmp-vol /root/tmp-pool/tmp-vol file 3.00 GiB 2.00 GiB This commit uses the correct vol->allocation instead of incorrect vol->capacity, so the output of the commands above looks like this: [root@localhost ~]# virsh vol-resize tmp-vol --pool tmp-pool 3G --allocate [root@localhost ~]# virsh vol-list --pool tmp-pool --details Name Path Type Capacity Allocation ------------------------------------------------------------- tmp-vol /root/tmp-pool/tmp-vol file 3.00 GiB 3.00 GiB Moreover, if the '--alocate' flag was used, we must update the vol->allocation member in storageVolResize API too, not just vol->capacity.
