LVM options

[Krishna Prasad]

Hello all,

I have a HP-UX / Linux LVM question.

In the HP world there has been the vgchange -s /dev/vg## option to make a volume group and its logical volumes in it sharable.

When I look at the Linux lvm.1.03-9 commands, I do not see this option available. The commands seem to be very close ( at least the names of the commands) However, no -s option for sharable drives. I am wondering if there is a different version of LVM that should be installed?

This option is very import for this project. We are attempting to install Oracle OPS on Linux. Along with sharable drives we will also have the need for clustering software.

Any suggestions on Linux clustering software would also be appriecated.

Hi,

afaik, sharing drives is not supported by the linux-lvm package. it is modeled after the hp-ux lvm package, but this doesn't necessarily mean that it supports al options that are supported under hp-ux.

You should take a look at the Global File System (GFS), which was also developed by the company that initially released linux-lvm. More info can be found on http://www.sistina.com. Unfortunately, GFS is not free as in beer.

There are other clustering possibilities (OpenMOSIX might be a good option: http://openmosix.sourceforge.net/), but you'll just have to decide for yourself which products is best suited for your environment.

Here's a link to more info on HA configurations with linux: http://linux-ha.org
