fallocate() support via NFS

[marichek]

Hi people,
I wonder whether fallocate() that is announced on NFS ver. 4.2 is implemented on FreeNAS?
Thank you.

Also it written to work on RH 8:
https://access.redhat.com/documenta...ems/mounting-nfs-shares_managing-file-systems:
"Space reservation
Permits storage servers to reserve free space, which prohibits servers to run out of space. NFSv4.2 supports the allocate() operation to reserve space, the deallocate()operation to unreserve space, and the fallocate() operation to preallocate or deallocate space in a file."

The fallocate command looks specific to Linux. You could try asking on the FreeBSD forums if there is a FreeBSD equivalent.
