Point is i now have 2 servers running OpenBSD for FTP and HTTP, 1 running as a filtring bridge, plus a management station, i m looking at replacing some more linux systems which i m growing to dislike. LVM/EVMS gives flexibility in managing storage hence the question to know if something similar was/is available Lyndon Nerenberg a icrit : OpenBSD doesn't have any volume management tools ala lvm and friends. If you don't have other requirements that tie you to OpenBSD specifically, you might want to look at some of the GEOM-based providers in FreeBSD. If you give a more detailed description of what you want to do you'll likely get better answers. --lyndon iD8DBQFGTVBx8B8RxF4jfhQRAgs0AJ9cLhQRr9Bbw8w+6tNbAWwYdeIz2ACeNnDG y1YkwjJpXwsjDjpK36KiFlc= =Wm7h -END PGP SIGNATURE-

Also, the Express releases of Solaris are shipping ZFS in addition to the traditional Solaris volume management tools. As a SAN storage engine, that's one of your better places to start. Use the right tool for the right job. OpenBSD isn't what you want for the SAN. But it is what you want to use to secure access to that SAN. --lyndon
Re: Volume Management
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Fist of all thanks for this enlightening answer, i m really trying to reduce the amount of different OSes i have to support at the moment, OpenBSD as been a wonderful replacement for web serving and ftp services plus of course network managment. ZFS looks indeed quite interesting and i will take a close look at it plus the Solaris volume management tools are quite adequate for the job i have in mind, namely replacing a crappy dell powervault running some crappy win2000 storage (dont ask, i wasnt in the company when this was bought and has been causing a lot of troubles). Down the line the ideal solution would be to standardize on one OS but a stopgap solution that allow me to get away from the aforementioned dell box is already a nice step. btw, is there any plan to include volume management in a future release?

Re: Volume Management
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Snapshot, online resize and shrink, the ability to move the datablocks from one storage media to another without having to unmount or otherwise make copies of the datas, most importantly to me is the flexibility it allows in managing a resource that has a tendency to get overabused by users.

Re: Volume Management
-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.

Much appreciated. There is no volume manager in OpenBSD. Use a combination of RAID and ccd, if so inclined; 4.2 might feature a new software RAID framework (or not; I've not heard anything official, besides some cvs commits on 'softraid').
