You have done a risk analysis and if you are happy that your NTFS
filesystems could be corrupt on those ZFS ZVOLs if you lose data then
you could consider turning off the ZIL. Note though that it isn't
just those ZVOLs you are serving to Windows that lose access to a ZIL
but *ALL* datasets on *ALL* pools and that includes your root pool.
For what it's worth I personally run with the ZIL disabled on my home
NAS system which is serving over NFS and CIFS to various clients, but
I wouldn't recommend it to anyone. The reason I say never to turn off
the ZIL is because in most environments outside of home usage it just
isn't worth the risk to do so (not even for a small business).
People used fastfs for years in specific environments (hopefully
understanding the risks), and disabling the ZIL is safer than fastfs.
Seems like it would be a useful ZFS dataset parameter.
