Hello all!
I was starting an install last night on a Compaq Proliant 7000 with 2 hardware RAID controllers. I had set up partitions (nonLVM) for / /boot and swap....all on one controller. I had one partition on this controller that was LVM dedicated. All the controller 2 were one big LVM.
I had successfully created all directories on the logical volumes per http://www.gentoo.org/doc/en/lvm2.xml, (/usr, /var, /opt, /home, /tmp)....and mounted everything successfully, and chrooted into the environment.
I had continued with the install, and had gotten to the part where you grab the lastest version of portage....and then performed the emerge --sync to update portage. This had completed 100% .
At this point...power went out.
This morning...I fired up the machine...all appeared to have recovered successfully on the RAID arrays. I set up ssh again (I'm doing this install remotely)....I turned on swap. I was starting to mount the partitions again. I successfullly mounted the / /boot and was starting to mount the LVM volumes...and ran into problems.
I got this:
| Code: | livecd ~ # mount /dev/vg/usr /mnt/gentoo/usr
mount: special device /dev/vg/usr does not exist
|
Now...I'm kinda stuck. Are these volumes gone? If I start again with the vgcreate and other commands...will that not delete any data that has been put there from unzipping Stage3 and portage?
Is there a way to recreate/remount the LVM volumes with the data already put on them...back to the state I was at before the power outage without starting from scratch?
Thanks in advance!

I did a vgchange -a y vg and it came back to life...and I can start remounting and continue to install now it appears.
Hope maybe this helps someone else in the future,
