Subject: A stackable filesystem to trace low level filesystem operations
Date: Tue, 3 Jan 2012 16:20:21 -0500	[thread overview]
Message-ID: <CAFFtA8429YabMVLp-f15GXBknK+W2oMpqYkZT42zLFaSJ-RBVA@mail.gmail.com> (raw)

Hi All,

Sorry but this isn't a ext4 specific question but a general filesystem question.

I am looking for a way to track filesystem level operation like
operation(read/write), filename, offset, size of read/write, pid of
the requesting process. The goal of my project is to collect such
traces and understand access usage of directories and more. I would
like to filter other operation like open,close, etc and requests to
procfs, etc. There was a stackable file system earlier called Tracefs.
It isn't supported anymore though. The original paper can be found
here: filesystems.org/docs/tracefs-fast04/tracefs.ps

Can you please suggest me what is the best option i have. I am
currently looking at SystemTap.

Thanks,
Sushil
