Ticket #5967 (new enhancement)
use posix_fallocate() for preallocated hard disks when possible
|Reported by:||bjacke||Owned by:|
when creating a new hard disk it would be good if preallocated (fixes size) hard disks would be created via posix_fallocate when that call is availbale. On recent Linux systems this call will allocate the whole space very fast and efficiently when XFS or ext4 is being used as filesystem.
