[gentoo-user] mdev and lvm2
Hello List, What is the status of using mdev (instead the ever growing udev) together with lvm2? Reason for my question is that at https://wiki.gentoo.org/wiki/Mdev it says One beta tester reports getting close with lvm2, but it's not there yet..

I had lvm2 partitions running under mdev without problems. (They were also RAID-1, just for completion's sake.) The only change I had to make was to my /etc/fstab. Where I previously had: /dev/vg/usr /usr options under udev, I then needed /dev/mapper/vg-usr /usr options instead. mdev failed to create the /dev/vg directory. With this change, my system worked quite happily. Sadly, I went back to udev when xf86-input-evdev-2.7.0 started depending on udev, back in June last year.

LVM can be configured to double-check udev to make sure all the /dev entries are done correctly. By default this is not switched on. See /etc/lvm/lvm.conf It might solve that part. It solves some udev issues on one of my systems where the links are not handled correctly by udev for snapshots. -- Joost -- Sent from my Android phone with K-9 Mail. Please excuse my brevity.
