[OmniOS-discuss] ZFS pool allocation remains after removing all files

[Filip Marvan]

Hello,

yes, VAAI could be probably the answer for vmware, and for example NexentaStor have some VAAI support as I know, but there were many problems with that (based on posts from users on Nexenta's forum) like freezing under heavy load and so on.

I gues, it will be very complicated to bring VAAI support to OmniOS.
