Re: OT: how to increase RAID space
UFS/FFS probably wont deal well with the underlying logical-physical
disk size changing (bytes/section, number of sectors, etc.). Even if it
was pure concatenation.
No, an LVM2/VxFS is needed.
Also, shops that can afford SAN and high end RAID tend to be able to
provision temp space to store media while they expand and re-create
volumes.

yes, i realise you mentioned it . You'd imagine some raid card manufacturers
would have something as flexible as LVM built into their cards by now... maybe
someone does already.. ?

OT: how to increase RAID space
Hi, I know this is not specific of FreeBSD, but I have a server with hardware RAID 5 disk (4x35 GB). Is there a way to change to bigger disks, except copying all the RAID to a temporary disk, and replacing my RAID?

... and the obvious one of adding new drives and mounting them as part of your
tree...?
that's what a volume manager (such as LVM2 in linux, Veritas Vol Mgr , and
vinum (I think) in FBSD 4 ) do - they abstract the hardware storage layer.
I believe work is being done to further abstract geom so that an vol manager is
doable in latest versions of FreeBSD... It may be possible to do it now with
geom, but I really dont know how.

Re: OT: how to increase RAID space
Quoting Olivier Nicole [EMAIL PROTECTED]: that's what a volume manager (such as LVM2 in linux, Veritas Vol Mgr , and vinum (I think) in FBSD 4 ) do - they abstract the hardware storage layer. That is hardware RAID. It depends on what you have. If you have a 5/6 RAID setup then you might get away with simply adding a disk. This will work from the RAID point, I just don't know how FreeBSD will feel about this. Perhaps the manufacture has special tools for this. -- Alex ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
