VG availability

[Sandor Horvath_2]

Hi !

Can I display VG availability anyway ?

Thanks, Saa

What do you mean "VG availability"? Are you wanting to see if the volume group is activitated or not?

You can try doing a 'vgdisplay vg_name'. If the volume group is activated then you will see information about it. If it is not activated, then vgdisplay will give an error like the following:

# vgdisplay vg04
vgdisplay: Volume group not activated.
vgdisplay: Cannot display volume group "vg04".

Hi !

I mean the VG is clustered or not,
activated or not,
shared or not,
excusive activated or not.

Thanks, Saa

Hi Sandor:

'vgdisplay' will return the VG status with an optional 'exclusive' notation if the VG is activated in an MC/ServiceGuard node. On nodes on which it isn't activated, vgdisplay will return 'Volume group not activated.'. This distinguishes an activatable VG from one that simply isn't known to the system. In that case, one gets 'Volume group "/dev/vgXX" does not exist in the "/etc/lvmtab" file'.

...JRF...
