Hi,
I have a 1.5TB drive (/dev/sda) that failed but may have started failing
over the the previous week (there was a point where the system did a
fsck on the vg which I thought was related to the system rebooting after
a power failure). I didn't notice anything untoward until today when I
gather the drive finally failed.
The thing is that when I run the various commands, there is nothing to
suggest that this drive is part of the vg yet I know it was
# vgdisplay

From the above I should be able to physically remove the drive and add
a new one (to the VG) using the standard procedures?
Thanks in advance,
Jongi
