-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 dear Ted, I m not after a fight here, i m simply asking if a tool similar to lvm, evms or vvm is available under OpenBSD. Also yes it is true that it is higly dependent on the filesystem. lastly i m mentioning lvm because it is a well know package nothing more. pvmove in lvm1 could be a bit tricky and the prefered solution was to do it offline, it is now much better in lvm2, still even the ability to do it offline is better than no ability in my opinion.
so while we could discuss the finer points of one solution over another for a while i m just happy to have an answer to my initial question. ps: this is in no way an attack after one of OpenBSD developer and most certainly someone better qualified than i am to know and understand the finer points of a system like lvm (the concept not the package), i merely miss some of the ease of use i have been acustomed to have while working on other systems.
