We are seeing the following error at boot and appear to have lost some partitions....

Whats the output of

# lvs

Please can you post your /etc/fstab file? /dev/pve/data should be mounted on /var/lib/vz
 
vpshost9:/home# lvs
LV VG Attr LSize Origin Snap% Move Log Copy% Convert
data pve -wi-ao 1.70T
root pve -wi-ao 96.00G
swap pve -wi-ao 23.00G

Mounted /dev/pve/data manually and it appears to be working ok..

/etc/fstab is:
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/pve/root / ext3 errors=remount-ro 0 1
/dev/pve/data /var/lib/vz ext3 defaults 0 1
/dev/sda1 /boot ext3 defaults 0 1
/dev/pve/swap none swap sw 0 0
proc /proc proc defaults 0 0
