Yes, that would have helped a lot. I can see in file /etc/lvm/backup/vg_devserver that the lv_root LV has been extended by a mere 32 Megabytes (yes, Mega) on the missing physical volume. Do you still have the additional disk? The best thing to do would be to put it back, make a partition on it, and then re-create the missing PV. I'll assume that the new partition is /dev/sdb1. Adjust all references in the following if it si something else.
I don't think I have that disk alive, take a look to this image http://imgur.com/jMuhM03 this is how my disk looks like
Make a copy of /etc/lvm/backup/vg_devserver on vg_devserver.bak, and then run
pvcreate -v --restorefile vg_devserver.bak \ --uuid "vSbuSJ-o1Kh-N3ur-JYkM-Ktr4-WEO2-JWe2wS" \ /dev/sdb1This is the result of the command above:
# pvcreate -v --restorefile /etc/lvm/backup/vg_devserver.bak --uuid "vSbuSJ-o1Kh-N3ur-JYkM-Ktr4-WEO2-JWe2wS" /dev/sdb1 /dev/root: read failed after 0 of 4096 at 27522957312: Input/output error /dev/root: read failed after 0 of 4096 at 27523014656: Input/output error Wiping cache of LVM-capable devices /dev/root: read failed after 0 of 4096 at 27522957312: Input/output error /dev/root: read failed after 0 of 4096 at 27523014656: Input/output error Couldn't find device with uuid vSbuSJ-o1Kh-N3ur-JYkM-Ktr4-WEO2-JWe2wS.

You will have to find the archived configuration from before you tried to extend that LV, and restore that configuration. Let's see what file you have. Post the output from
grep -H 'description =' /etc/lvm/archive/vg_devserver*
