[linux-lvm] Cuncurrent access to a vg from two hosts

[Wiktor Wodecki]

Hello,

I'm curious if lvm1 allows me to access the same volume group from to
different machines (of course not accessing the same lv's in this vg). I
have two machines connected to a storage array, that's why I ask. Is the
filesystem operations on the LV affecting the VG so that this could lead
to inconsistencies?

You can access different LVs in the same SAN shared VG presumably you
make changes to the VG (eg: create, resize LVs) when it is active (vgchange -ay)
on one of them only. After done with the changes, run vgscan and "vgchange -ay" 
on the other machine.
