How to mount a LVM partition using a live cd

brazilian_user · 11-12-2006, 08:07 AM

Hello

I'd like to know how I can mount a LVM partition using my live cd.

When I boot my Red Hat it fails to check the file system with fsck at the boottime, so I'm unable to keep booting.

Actually I can access the / partition, but it is mounted with read only method and I can't edit any file. So I want to mount the LVM partitions using a live cd to edit and copy some files through the network...

Any Ideas??

Thank you

Rodrigo

You need to boot with a LVM-enabled live CD. Then, as root, you do a "vgscan" and mount the file system in the usual way (i.e. "mount /dev/<vgname>/<lvname> <mountpoint>").

Hey uselpa thank you!!

I'm using Debian's live cd, but I really don't know how I can enable the LVM or if this specific live cd has this caracteristic. I've tryied F1 before boot but I didn't see any option to enable LVM on boot...

Do you know if Debian's live cd project has suport to LVM or if it is possible I install it using apt-get...??

Best Regards!!

No I don't know that, but as Debian supports LVM-enabled installations my guess is that it does. If the "vgscan" command works and afterwards you have the /dev/VG/LV device node then it's working. Personally I use the RIP CD so if nothing works I can tell you how to do it with RIP.
