Hello!
- Pop in new disks
- Initialize new disks as LVM PV (pvcreate)
- Add PV to existing volume group (vgextend)
- Move physical extents from old PV to new PV (pvmove)
- Remove old PV from group (vgreduce)
- (Optional) wipe PV signature from old disks (pvremove)
- Pop out old disks
Perhaps this is a bit more elegant than that what i've suggested.
As this idea is repeatedly being regurgitated here for apparently no
reason, I've created a blog post about it. You can get it from
Planet HA
(http://www.planet-ha.org/#Internal+metadata%2C+and+why+we+recommend+it
).
Yes. I've read your explanation and it seems very reasonable. I didn't
think about your points.
Maybe a hint about your blog post would be nice. - Especially for those
who don't run professional systems without battery backed RAID
controllers,
like myself. I run a RAID1 and I did not see the point in buying a RAID
controller for RAID1 - back then.
Read my blog. :)
I'm following the feed for quite a while now. You're not posting very
often,
but when you do it's usually good read. :-)
Thanks,
juergen
