Subject: [PATCH V2] xfsprogs: suggest "-d" option for repair of RO mount
Date: Mon, 18 Nov 2013 10:02:05 -0600	[thread overview]
Message-ID: <528A39FD.5090109@sandeen.net> (raw)
In-Reply-To: <528261AD.50501@redhat.com>

We can offer the suggestion of a "-d" repair, if we're
in single-user mode with i.e. the root fs mounted readonly.

This change suggests -d to repair any RO mounted fs.

e2fsck allows this, and users are used to being able to
do it in single-user mode.  A separate patch will recommend
a reboot after repair completes.
