Linux and AIX LVM difference ?
I'm new on Linux lvm - all my experience in lvm is on AIX and I noticed some fundamental differencies. In AIX lvm configuration(all volume groups and etc) are per operating system - if two AIX OSes share some SAN disk and one of OSes has volude group varied on, the same pv looks only like some pv with unknown content to other os(if other os never imported that pv)
While in Linux things look different. I have dual boot system(slackware + debian) and debian is installed on lvm volumes. Slackware allways sees these debian lvm volumes. If I export that volugroup in slackware, debian can't boot, if debian boots - slackware sees that volume group.
Operations like export or activate are global to vg, not per operating system ?
So if I want to use multiple volumegroups they all allways be visible to operating system whitch detects it's pvs?
How about names than - I can't have volume groups with same name even these vgs are created for different oses ?
