Hi Simone, I'm facing an weird behavior with my dedicated iSCSI Hosted Engine Storage Domain (this LUN has 50GB in size, which is more than enough for the engine storage domain). The engine vm itself is using 2.8G as you can see below, but the storage domain is consuming 49G. I don't have templates or snapshots...(Sreen Shots  attached) Do you know whats happening? and I'm receiving Critical, Low disk space messages which are non sense.

Thanks

-Luiz

Yes, it is.

A storage domain on block devices requires 5 or 6 GB of ancillary data
due to extents size and, if I'm not wrong, there is a low disk space
threshold at about 4 GB; using slightly larger LUN will help.
