restore question

Hi,

I have a problem with using lvm and I'd be grateful for some advice.

I have a data volume group "datavg" on a mirrored raid partion that was running fine until I experienced a system crash. After the crash the /dev/md0 raid device was not recognised by the lvm system and neither was the datavg. After finding some advice on this list I ran the commands:

pvcreate /dev/md0
vgcfgrestore -n datavg /dev/md0
vgscan

to restore the datavg. This seemed to work, however, the volume group seems to have been restored to a point some time in the past, i.e. there are many files missing. I'm not too sure how this could have happend as all the reading I've done seems to suggest that the vgcfgrestore command should just have restored the configuration and not any data. Have I somehow restored a snapshot of the volume group? Does anyone have any suggestions as to how I might retrieve my data?

Any advice would be very welcome.

Regards,
Fraser

lvm version: 1.0.8-4

Right, the vgcfgrestore restored the most recent LVM metadata to the device.

This doesn't change any data content withing Logical Volumes.

Hard to tell waht happened without more information.

What does lvscan show ?
What does lvdisplay show on the LVs ?
