[linux-lvm] funny PV action

[Christoph Resch]

Hi all,

may someone kindly assist me in thei quite funny behavior of LVM

i work on a runnging LVM system .. everything works as it should BUT:

when running pvscan i get 

root at prime:~# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/md1" of VG "system"   [19.97 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/md2" of VG "dataraid" [13.88 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/md3" of VG "dataraid" [68.36 GB / 0 free]
pvscan -- total: 3 [102.24 GB] / in use: 3 [102.24 GB] / in no VG: 0 [0]

# well /dev/md1 is my system ( / , /usr, /var ,... ) it works quite fine :-o

root at prime:~# vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found active volume group "system"
vgscan -- found active volume group "dataraid"
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume 
groups

# well thats great ;-)
