[ovirt-users] Re: Sparsifying VM disk not working
Is it also broken on the NFS data domain, or only on iSCSI?
As I understand, sparsifying isn't supported on iSCSI data domains.
I am not sure of the reason why iSCSI domains don't support sparsify, but
it would be great.
I'd love an input from oVirt storage gurus to understand the limitation

Hello,
i cannot get sparsifying to work in lastest oVirt 4.5.4 release (not that
i have tried with a previous release)
I have two Data domains connected to oVirt using iSCSI & NFS.
I created 2 testvm's and 50GB thin provisioned qcow2 disks for each, made
some temp files, remove them and tried to sparsify, but it does not work.
Error i am getting is:
Error while executing action: Cannot sparsify Virtual Disk. Sparsifying is
not supported for QCOW2 disk testvm1_Disk1.
In virtual disk options i have enable, Bootable, incremental back and for
one of the images i enable discard for testing purposes.
What am i doing wrong?
