Subject: [linux-lvm] "cloning" from ide to sata drive, can't find root
Date: Mon, 30 Oct 2006 17:36:51 -0500 [thread overview]
Message-ID: <1162247811.45467e83cae80@webmail.highstream.net> (raw)
I did a straight up mirroring of a drive doing dd if=/dev/hda of=/dev/sda where
the src is an ide drive and target a sata drive and not unexpectedly it can't
find the root device on boot.
Typing out the error message ...
[snip]
Reading all physical volumes this may take a while ...
No volume groups found
Unable to find Volume Group "VolGroup00"
[snip]
I used a rescue disc distro and used dd to extract info subtible for
vgcfgrestore,
after which I did some other finagaling with vgchange and I can mount the volume
and view the data on it, so it's there, vgscan/pvscan and lvscan all show it ...
but as mentioned boot it's just not picked up on boot so it can be mounted as
'/'. I thought I fixed it with the vgcfgrestore (changing /dev/hda2 to
/dev/sda2) but obviously not ... any guidance is appreciated.
thank you,
brian
