Subject: [Patch review 0/1] introduce lvm forcevg option to forcibly deactivate the whole vg
Date: Thu, 14 Sep 2017 15:53:27 -0500	[thread overview]
Message-ID: <20170914205327.GA8365@redhat.com> (raw)

Hi Zhang,

I discussed this with Alasdair who had the good idea that we could do this
with just a couple of dmsetup commands, e.g.

dmsetup info -c -S "uuid=~LVM && vgname=$VG && lv_layer=\"\"" -o name --noheadings | xargs dmsetup wipe_table

If this works, I think it would be a nicer solution than going through the
blkdeactivate script.

Dave
