I spent nearly an hour in #LVM on freenode today trying to get this figured out...
Turns out the PE limit was 65,535 (not 65,000) and that lvm2 has no limit on the number of PE's! So now I'm left trying to decide on a good size without a lot to base it on.
Could you explain why LVM renders journals useless? I'm having a hard time trying to work out why... and unfortunately nobody i have asked knows enough about it to have heard about that problem :/
saying that, i have been thinking about a UPS for awhile i just can't afford the dam things, just finished paying off a £500/$1000 overdraft that i blew on beer and pizza... perhaps i could spend it on something worthwhile next time the cash goes to my head!
