Just one important note regarding the udev support and the udev rules
shipped since version 2.02.68. From the lvm2 upstream commit message:
Fix udev rules to handle spurious events properly.
We can use DM_UDEV_PRIMARY_SOURCE_FLAG to identify the spurious events
and use it as an indication that the device has already been activated before
(and hence we can find this property in udev database).
WARNING: This change requires udev startup script to preserve udev database
from initrd. All the information stored there during activation of devices
is important for the initial "udevadm trigger --action=add" call that is
used in udev startup script. If not done this way, udev startup script needs
to define DM_UDEV_PRIMARY_SOURCE_FLAG=1 property for any ADD events it uses.
This is something we discussed with upstream udev before. But since each
distro maintains its own udev init script, care must be taken to have this
script fixed/modified for this to work properly before rebasing lvm2.
As I checked Debian's udev init script, this one was removing the udev database
from the initramfs as well, it's just one line found in /etc/init.d/udev:
if [ -z "$TMPFS_MOUNTED" ]; then
unmount_devpts
mount_tmpfs
[ -d /proc/1 ] || mount -n /proc
else
# and clean up the database of the initramfs udev
rm -rf /dev/.udev/
fi
That's the "rm -rf /dev/.udev/" - this one needs to be removed. I've already
sent
a notice to Debian's udev maintainer and it should be removed soon, I hope
(Kay Sievers, the udev upstream maintainer, was on CC who acknowledged the
change).
So, please, watch this change in udev package to prevent any undesirable and
strange situations. Thanks.
