Right, I appear to have just done raidhotadd /dev/md1 /dev/md3, in
stead of /dev/md1 /dev/hdh3. Oops. It doesn't complain that md3 is
active either. More oops.

md3 and md4 are in a linear lvm (lvm1 on 2.4.20ish kernel) of 222Gb in size, and md1 is a 100Mb
raid5 partition (/). This means that the first 50Mb has probably been

This didn't cause the machine to die horribly, only not to come back up.
Given I have probably only overwritten about 0.05% of the data, I hope it
can mostly be restored. However, vgscan and vgchange -ay refuse to do
anything, and vgcfgrestore reports unhelpfully that "physical volume
/dev/md3 doesn't belong to volume group vg0"

Any ideas how to fix this without wiping the whole thing (I have
backups of critical stuff, but not all of it by a long way). I'm in the
irc channel as "mjj29", if I'm around when everyone else is.
