After a lot of testing and fun I have freed a box for production Xen
installs. When I try to install Xen onto an LV things go quite wrong.
If I create and mount an LV and install Xen into a file backing then all
works fine.
The process I am using goes like this...
Create an LV:
# lvcreate -L 2G vgxen -n myxen
Install FC5:
# xenguest-install.py --name=myxen \
--file=/dev/vgxen/myxen \
--ram=256 \
--location=http://install/5/i386/
I preform a minimal install and it finishes without errors, the only
thing I customise is the name of the volume group (VolGroup00 => vg00)
and the logical volumes (LogVol00 => lv00 etc), I'm not a fan of the
StudlyCaps default :-)
The I start the instance
# xm create -c myxen
Only to be confronted with this:
Setting up Logical Volume Management: 2 logical volume(s)
in volume group "vg00" now active

Error reading block 32 (Attempt to read block from filesystem
resulted in short read).
/boot: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
(i.e., without -a or -p options)
Trying to fsck the /boot filesystem gives the following errors:
Error reading block 32 (Attempt to read block from filesystem
resulted in short read). Ignore error<y>?
Does anyone have any ideas as to what is wrong or what I am doing wrong?
Take care,
Gawain
