This could be related to a consistency problem with the dynamically
assigned LVM minors. vgscan creates a /etc/lvmtab and /etc/lvmtab.d
(and the correcsponding dev files -- can't remember of head) on your
_ramdisk_. Later LVM tries to access the possibly inconsistent data
(and dev files) on your hard disk.
Please have a look at
Please try the following:
I assume the vgscan on the ram disk completes w/o problem.
Could you transfer the /etc/lvmtab, /etc/lvmtab.d/*
to your hard disk and make sure the LVM dev files are the same?
You should be able to simply call an interactive shell in the
