Source: linux
Version: 3.5.2-1~experimental.1
Severity: important
Justification: fails to boot
Tags: upstream
Hi,
Trying to boot with the kernel from experimental, I get (typed by hand):
[ 1.949115] sda: sda1 sda2 sda3 < sda5 >
[ 1.949751] sd 0:0:0:0: [sda] Attached SCSI disk
Volume group "data" not found
Skipping volume group data
Unable to find LVM volume data/root
[ 1.994926] Refined TSC clocksource calibration: 2294.254 MHz.
[ 1.994977] Switching to clocksource tsc
done.
Begin: Waiting for root file system ... done.
Gave up waiting for root device.
followed by some advice about how to diagnose. At the busybox prompt,
looking in /dev/mapper, I only see "control" and "data-swap". Similarly,
(busybox) lvm lvscan
ACTIVE '/dev/data/swap' [4.66 GiB] inherit
[...]
inactive '/dev/data/root' [952.00 MiB] inherit
inactive '/dev/data/usr' [...]
So for some reason only the lv for my swap partition is being activated.
Reproducible with upstream kernels, too. Bisects to v3.5-rc1~164
(Merge branch 'core-rcu-for-linus' of
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip, 2012-05-21),
which is puzzling. That kernel reproducibly fails to find the root
device. I'm retesting its second and first parent now.
Bugscript output for the (working) wheezy kernel, fstab, and lvm.conf
attached.
Ideas?
Jonathan

#

# logical volume has failed. It is left to the user to run
# 'lvconvert --repair' manually to remove or replace the failed
# device. As long as the number of failed devices does not
# exceed the redundancy of the logical volume (1 device for
# raid4/5, 2 for raid6, etc) the logical volume will remain
# usable.

# "allocate" - Attempt to use any extra physical volumes in the volume
# group as spares and replace faulty devices.

# 'mirror_image_fault_policy' and 'mirror_log_fault_policy' define
# how a device failure affecting a mirror (of "mirror" segment type) is
# handled. A mirror is composed of mirror images (copies) and a log.
# A disk log ensures that a mirror does not need to be re-synced
# (all copies made the same) every time a machine reboots or crashes.
#
# In the event of a failure, the specified policy will be used to determine
# what happens. This applies to automatic repairs (when the mirror is being
# monitored by dmeventd) and to manual lvconvert --repair when
# --use-policies is given.
#
# "remove" - Simply remove the faulty device and run without it. If
# the log device fails, the mirror would convert to using
# an in-memory log. This means the mirror will not
# remember its sync status across crashes/reboots and
# the entire mirror will be re-synced. If a
# mirror image fails, the mirror will convert to a
# non-mirrored device if there is only one remaining good
# copy.
#
# "allocate" - Remove the faulty device and try to allocate space on
# a new device to be a replacement for the failed device.
# Using this policy for the log is fast and maintains the
# ability to remember sync state through crashes/reboots.
# Using this policy for a mirror device is slow, as it
# requires the mirror to resynchronize the devices, but it
# will preserve the mirror characteristic of the device.
# This policy acts like "remove" if no suitable device and
# space can be allocated for the replacement.
#
# "allocate_anywhere" - Not yet implemented. Useful to place the log device
# temporarily on same physical volume as one of the mirror
# images. This policy is not recommended for mirror devices
# since it would break the redundant nature of the mirror. This
# policy acts like "remove" if no suitable device and space can
# be allocated for the replacement.
