I inadvertantly blew
away the partition table on /dev/sdo that was in use. While the system is still
running and no errors have occured...yet, I need
to get the partition
table restored and be able to vgdisplay the datavg. Below is the sampling
of error messages.
<root@paxton:/proc/lvm># vgdisplay
datavg

Is it safe to clear
VGDA using the "dd if=/dev/zero of=PhysicalVolume bs=512 count=1" shown in
the pvcreate man pages and the come back and
recreate the
VGDA using pvcreate, or use pvcreate outright not using the dd method? Or,
is there a better method to get /dev/sdo back into the
datavg
group while
recreating the partition table?
