Errors in vgdisplay

Hi,

I am seeing the below errors when I do a vgdisplay on a particular vg.
However the vg is online & the filesystem is mounted & accessible.
can a vgscan -a after moving the lvmtab file get rid of these errors. Do I need to activate the VG after doing a vgscan (vgchange -a y )? Can the vgscan be done online without affecting the application or the db?
Please help.

Re: Errors in vgdisplay

Hi ,

If you are sure that the specified LUN is not used in your VG , try the below steps to get rid of that disk form vg

#vgreduce -f
#vgchange -a y


and the above command can be done online with out service interruption

Re: Errors in vgdisplay

yes you can do the vgscan online.

mv /etc/lvmtab /etc/lvmtab.old
vgscan -av
####Check if the new lvmtab has all disks###
vgchange -a y

and you should get rid of the messages
Windows?, no thanks
