Re: [CentOS] figuring out LogVol details for mount
When you boot into rescue mode are you given the option to continue-mount or read-only-mount the system to /mnt/sysimage? You could try to view /mnt/sysimage/etc/fstab to find the partition types. Regards, W. Hello everyone, I was, of course, a numbnut for suggesting this. I don't normally LVM the / partition, so I didn't think of it. I'll try to, er, open my mind out of my environment for future helpful suggestions. Actually, the thread was an example of why I don't LVM /. I think it adds another layer I'd rather not have to deal with when things go casters up. But that is just My Way and it is not The Only Way. Not a knock on Neuby, since it wasn't installed by him. How goes the battle, by the way? W. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

They'd all be mounted under /mnt/sysimage, and would be revealed by the df or mount commands. If this isn't available, the pvscan, vgscan, and lvscan commands are all available in the bootable CD, *but* they are all built into the underlying lvm command. So type lvm pvscan to find what physical volumes are set up for LVM, lvm vgscan to find the volume groups, and lvm lvscan to find the volumes. Re-activating an 'inactive' LVM due to a messed up configuration or volume is left as an exercise for the reader. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

But I am able to see partitions using fdisk and check LVM volumes. I am not sure which volume of that contains OS install VolGroup00-LogVol00 or VolGroup00-LogVol01.
