RE: [linux-lvm] logical volumes extending beyond 1 machine

[Diehl, Jeffrey]

Actually, I think hew as refering to MFS (mosix fs).  Unfortunately, this
probably won't work since it's not really a block device, it's much more
like an nfs mount.  I've been watching this thread and have yet to see
anyone answere if a network block device would work.  I think it would be
neat...

You mean running LVM through ENBD, for example ?

Umm, not to be anal or anything, but the MOSIX team doesn't develop GFS,
Sistina Software does.  You know, the same group that's heading up LVM?
The same group that hosts this mailing list?  Please look at
http://www.sistina.com if you're still confused.

And yes, you might want to consider using GFS for your system.  :)

RE: [linux-lvm] logical volumes extending beyond 1 machine

[Diehl, Jeffrey]

10Tb!  I'm working on a database that is 369Gb and I'm having to fight a few
performance issues.  What database manager are you using?

Ah, thanks.  I guess what I was wondering was whether or not an NSF
mounted disk can be included in a logical volume defined by LVM.  I am
working with a large database, 10 TB, and am curious as to whether I will
need to break it up into more than 1 database file.

Couldn't PVs be network block devices?

[linux-lvm] logical volumes extending beyond 1 machine

[Damon Fasching]

Is it possible using LVM define a logical volume which includes disks from
more than 1 machine?
