Face-to-face so far I think - I've not been directly involved yet nor seen any
ideas in writing. It needs putting onto another bugzilla.

Where is that anaconda discussion? I've been successfully using an
ugly-but-effective wrapper script around lvm (in kickstart %pre) that
automagically implements various presumptions for when to auto-stripe and how
many stripes to use.

Yes - anaconda would then need to provide an option to enable the new
corresponding lvm option.
Separately, a discussion is beginning about how to link anaconda and lvm better
so anaconda doesn't have to second-guess how lvm will lay out the data.

Well let's try to deal with this.
Firstly, this is an lvm2 bugzilla. Any outstanding requests for changes to
anaconda should move to a different bugzilla.
For LVM I propose:
1. An lvm.conf setting that will provide a default value for --stripes in
commands that create new LVs. Commands that *extend* existing LVs will ignore
this and work as now, defaulting to continuing the striping of the last
segment.
This will be useful for people who have lots of disks and always have a decent
amount of disk space unallocated.
2. An allocation option for 'maximum reasonable' striping. The details are
still to be worked out, but the idea is to attempt always to stripe the data,
adapting the number of stripes to the circumstances.
(I might split these across two bugzillas now.)
