Red Hat Bugzilla – Bug 951661
Avoid calling fallocate(), even when supported, since it turns off XFS's delayed-allocation optimization
Last modified: 2014-06-18 03:47:23 EDT
Using fallocate() turns off delayed-allocation in XFS, and results in substantially slower behavior for PUT operations.
Assigning the bug to Chetan as he is currently working on it.
A default tunable can be used to disable the fallocate calls for gluster FS. That has been documented in the configuration files. The changes are now merged into the code.
