Thanks a lot bakunin for your replay that has very useful information especially for me. Really, I appreciate replies like this, because it includes the answer (problem's solution) & the useful knowledge.
Thanks again.
I asked the above question because I faced a problem. I have a Filesystem which mounted over a specific LV. This LV belongs to a VG that consists of 2 PVs. This VG has MAX PVs = 8, and this is the main reason for my problem & I will explain why later.
Recently, the percentage of used space from this FS reached 90% & to increase this FS a new storage has been allocated to my system on SAN. This new storage consists of 9 PVs. Obviously it isn't possible to add all these PVs & this my problem.
Unfortunately, the SAN admin restricted with a policy that prevent him from giving me the required size divided into less than 7 PVs. Also I don't think it is possible to change the MAX PVs for the VG, because I didn't see this option except during the VG creation.
Finally, how can I add these PVs to increase the FS size? According to my knowledge I think the solution is to recreate the VG.
If am right & the only way is to recreate the VG what is the best scenario to do that without losing the existing data?
Thanks in advance

I am running solaris 10 with Veritas. I want to extend a filesystem. It's an oracle partition (/ora12). How can I find out if there is space available to expand the filesystem and then how does one extend it.
I'm from the HPUX world and so LVM was always how I did things.
Thanks
