Description Gawain Lynch 2006-06-01 07:57:02 EDT
Description of problem:


Version-Release number of selected component (if applicable):
xen-3.0.1-4 & xen-3.0.2-0.FC5.3

How reproducible:
Everytime

Steps to Reproduce:
1. Create an logical volume to install to:
    # lvcreate -L 2G vgxen -n myxenvg
2. Install FC5:
    # xenguest-install.py --name=myxen \
        --file=/dev/vgxen/myxenvg \
        --ram=256 \
        --location=http://install.mylan.com.au/5/i386/

3. Start the instance
    # xm create -c myxen

Actual results:

  Setting up Logical Volume Management:   2 logical volume(s) 
      in volume group "vg00" now active
      [  OK  ]
      Checking filesystems
      Checking all file systems.
      [/sbin/fsck.ext3 (1) -- /] fsck.ext3 -a /dev/vg00/lv00
      /dev/vg00/lv00: clean, 19347/418080 files, 126997/417792 blocks
      [/sbin/fsck.ext3 (1) -- /boot] fsck.ext3 -a /dev/xvda1
      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>? 

Expected results:
The myxen domU should boot as it does when using a file backing.

Additional info:
Running the course of the fsck does not make any difference.

Trying to manually mount and write to xvda1 will cause ext3 journal errors and
the partition to be remounted read only.
Comment 1 Jeremy Katz 2006-06-04 14:59:24 EDT
The install succeeded successfully?  Are there any errors in dmesg of the xen0
or in /var/log/xend{-debug}.log?

Comment 7 Gawain Lynch 2006-06-04 23:06:17 EDT
Other than what apprears in the post install dmesg there are no other
interesting bits and the install finishes OK.

If I 'mount -o ro /boot', 'mount -o rmount rw /' and do an 'init 3' I can bring
the guest up to a useable state. 
Comment 8 Jeremy Katz 2006-09-25 16:58:56 EDT
This works now
