After this the logical volumes must be visible. Try mouting them and getting the data
After the command of vgchange, you must get some information on the numberof logical volumes which got activated.
This solved my problems. I got the following:
[root@Loke ~]# pvscan
PV /dev/sdc1 VG datadisc lvm2 [698,64 GB / 0 free]
PV /dev/sdb1 VG datadisc lvm2 [698,64 GB / 0 free]
PV /dev/dm-0 VG VolGroup00 lvm2 [148,84 GB / 32,00 MB free]
[root@Loke ~]# vgscan
Reading all physical volumes. This may take a while...
Found volume group "datadisc" using metadata type lvm2
Found volume group "VolGroup00" using metadata type lvm2
[root@Loke ~]# vgchange -a y
1 logical volume(s) in volume group "datadisc" now active
2 logical volume(s) in volume group "VolGroup00" now active
after that I mounted the device manually:
[root@Loke ~]# mount -t ext3 /dev/datadisc/LogDatadisc /home/<my home dir>/dl/
when it worked I edited /etc/fstab with the new mounting point.
