Subject: How to invoke the "discard" operation over btrfs
Date: Wed, 15 Dec 2010 21:24:34 +0800 [thread overview]
Message-ID: <AANLkTiko-0A4sDEK8TOOeJWq+BGZKt49raq+=krHMu4x@mail.gmail.com> (raw)
Hi all,
Is there anybody know how to invoke the "discard" operation over btrfs
filesystem? Does delete a file by "rm" will trigger the "discard"
operation?
If I want to trigger "discard" operation,how should i do? if there any
pre-requires? such as the device must be ssd, btrfs should be mounted
with "-o discard".
Any suggestion is appreciated.
Thanks a lot!
