Subject: barriers off by default?
Date: Mon, 12 May 2008 10:56:21 -0500	[thread overview]
Message-ID: <482868A5.1000102@redhat.com> (raw)

As I look at my shiny new 500G disks with 32MB of cache, I find myself
wondering why the default for ext3 and ext4 is to have barriers disabled.

This is a pretty dangerous default w.r.t. filesystem integrity on power
loss, no?

Thanks,

-Eric
