In case this helps focus minds, we had horrendous performance of a 30
1TB disk RAID10 with LVM on top of it (1MB chunks), so we ended up doing
RAID1 mirrors with LVM striping on top in order to alleviate it.
We were not in a position to try to debug why RAID10 would not play nice
with LVM, since deadlines were looming...
Cheers,
Iordan
