Hi all

I need your kind = assistance.

I have a machine with Linux LVM = file system. I=20 mistakenly moved my /* to /var/www/test and everything stopped=20 working.

We tried to use rescue disk, but rescue = did not see=20 the volume on the hard disk. We tried to mount the hard disk but got = superblock=20 error.

We reinstall the OS in a new hard disk = /dev/sda and=20 make the hard disk with /* problem as secondary = /dev/sdb.

Primary /dev/sda

Secondary dev/sdb = /dev/sdb1,=20 /dev/sdb2

I want to mount the /dev/sdb2 on = /newmnt I created=20 in the new OS. But /dev/sdb2 has the = same VG name=20 as /dev/sda2 - VolGroup00.

Please, how do I mount the /dev/sdb2 VG = VolGroup00=20 on /newmnt?

Will I be able to mv back the root on = the sdb2 i.e=20 mv /newmnt/var/www/test/* /newmnt/?

Kindly assist with procedure and = command. I have no=20 experience using lvm.

I attach the fiel = strucutre.

Thanks.

Ismail
