Increment cluster filesystem

I'm trying to increment a cluster filesystem, but as the cluster has monitoring, Am I need to increase this filesystem turning off the cluster and mounting all the filesystem as normal (vgchange -c n vgname, vgchange -a y vgname).

Thanks in advance.

Re: Increment cluster filesystem

Hi,

If you have onlinejfs and it is just a filesystem increase, then i don't think you should have any problem.

what is the monitoring you are talking about ?.

Hope this helps.

Re: Increment cluster filesystem

Hi,

What kind of monitoring are you talking about?. If you are not doing any customized monitoring, then ServiceGuard will not bother about the filesystems until it starts/stops the packages. You can safely unmount the filesystem (if possible), extend it and mount it back. If you have OnlineJFS, it is much easier as you can do it online. Even if the package is down, you don't need to do vgchange -c n etc., you simply do a 'vgchange -a e' just like serviceguard does.

Re: Increment cluster filesystem

I'm talking about any kind of filesystem monitoring from the cluster.

As this server is not administered by myself, I not quite sure if this server has that kind of monitoring.
