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

[Rune Tipsmark]

I am happy to test in our environment, we have some semi-live demo servers (10+ virtual servers) that are being used as in a real production environment with load on them etc.

If some VAAI works, should I be able to see it in VMware? Does it make any difference I use SRP to connect the LU's?

My VAAI status for each LUN is as follows:

naa.600144f0908abf5d00005391079d0008
   VAAI Plugin Name:
   ATS Status: unsupported
   Clone Status: unsupported
   Zero Status: supported
   Delete Status: unsupported

Br,
Rune

AND there are improvements to this for ZFS compliments of Delphix.

That is true.
