This is something I’d written awhile ago when using Centos. It should apply to Scientific Linux, as well.<\/p>\n
Here’s a little update, too. If your using a Linux live CD (eg. Slax) to recover files from a hard drive with a LVM partition these commands are handy as well. You can run the following to activate the partition for mounting::<\/p>\n
lvm lvscan
\nlvm vgchange -ay<\/p>\n
Anyway – about adding a second hard drive…….<\/p>\n
With only the secondary drive attached, place a Centos cd\/dvd in the optical drive and type rescue mode at the boot prompt.<\/p>\n
You will be asked some questions, the most important being about activating the LVM partitions – you do not want to activate LVM volumes at this point.<\/strong><\/p>\n Now, type:<\/p>\n lvm lvscan<\/p>\n You will, normally, see a LVM group with the name VolGroup00.<\/p>\n Very likely both of your hard drives will have LVM partitions that have the same names – usually “VolGroup00”. This won’t work, so do something like this to rename the secondary drives partition:<\/p>\n lvm vgrename VolGroup00 VolGroup07<\/p>\n I created a directory call \/harddisk2, and, added the following to rc.local to mount the second hard drive at boot time:<\/p>\n lvm lvscan Further, to mount a specific directory (in this case, \/etc) on the second hard drive the following works, although I haven’t tried it in rc.local yet:<\/p>\n mount –bind \/harddisk2\/etc \/mount2<\/p>\n UPDATE: the above does work in rc.local, and, adding the mounted directory as a share in smb.conf worked, as well. I assume you should probably start smbd and nmbd after the LVM activation, mount, etc. My rc.local file looks like this:<\/p>\n touch \/var\/lock\/subsys\/local This is something I’d written awhile ago when using Centos.
