[ovirt-users] Re: configuration of hyperconverged setup with ssd cache for slow drives
Create a vdo device with 'emulate52' and use that for your LVM's PV.

Hello,
After a serious struggle I finally managed to get ovirt-hosted engine with the
hyperconverged setup to work.
However I did not manage to get the ssd cache option for my slow sata drives to work.
The installation script complained about mismatching block sizes.
Is there a way to make the cockpit hyperconverged installation handle this ?
