[Gluster-users] posix_handle_hard [file exists]

Tue Nov 6 05:33:00 UTC 2018

I think this is because the way preallocation works is by sending lot of
writes.
In the newer version of ovirt, this is changed to use fallocate for faster
allocation.

Adding Sahina, Gobinda to help with the ovirt version number that has this
fix.
