Wow, I guess we got lucky then, huh?

/oldroot was not pre-existing... It was created to mount lvol3...
We did not remove it, and it was still there on reboot, so the disk did sync at some point. And we rebooted with reboot -qn.

I know it was risky, and perhaps (in hindsight, of course) a little sloppy, but that's what this particular box is for here - a learning tool and a training machine.

(Note to self: ask these questions before doing the action next time... Smilie )

I think that if the directory /tcb exists, HP-UX is in trusted mode and the passwd data is somewhere in /tcb/files/auth. But that's all I remember. Also I think recent versions of HP-UX can have a /etc/shadow file. (0 Replies)

NAME
pvck - check physical volume metadata SYNOPSIS
pvck [-d|--debug] [-h|--help] [-v|--verbose] [--labelsector] PhysicalVolume [PhysicalVolume...] DESCRIPTION
pvck checks physical volume LVM metadata for consistency. OPTIONS
See lvm for common options. --labelsector sector By default, 4 sectors of PhysicalVolume are scanned for an LVM label, starting at sector 0. This parameter allows you to specify a different starting sector for the scan and is useful for recovery situations. For example, suppose the partition table is corrupted or lost on /dev/sda, but you suspect there was an LVM partition at approximately 100 MB. This area of the disk may be scanned by using the --labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800): pvck --labelsector 204800 /dev/sda Note that a script can be used with --labelsector to automate the process of finding LVM labels.
