[opensuse] lvm boot fails with timeout in multipath

Boot with LVM root often fails on oS 13.2, and dracut starts the emergency shell. The messages beforehand are (copied with errors): timeout /sbin/multipath -i -u sda1 [slow multipath etc] dracut -initqueue PARTIAL MODE Incomplete logical volumes will be processed [another error message about a missing LVM partition] This issue looks similar to the one described in this[1] Ubuntu bug report.

Do you really need multipath? Then you probably need to give more details about your configuration. It is rather unusual on consumer grade systems.

Actually, I neither need it, nor did I know what it was about before I saw this error message. Multipath is disabled in yast, and I have no idea what to do to avoid the error in dracut. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I do not remember that dracut included multipath in 13.2 and I do not see it in my test TW VM either. Running mkinitrd -vvvvvv to increase verbosity may give some hint. But normally unless it is used for root device it should not be included. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I disabled it (omit_dracutmodules+="multipath") and boot fails immediately. If I leave it in, then there is a >50% chance that boot fails after a delay, searching for the root device.

It sounds like for some reason multipath is used for your root. Not sure what information to ask ... probably running supportconfig to gather as much as possible. Look for supportutils on software.opensuse.org. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

This means that multipath is not used on my system, if I'm reading it correctly.

Then, why does dracut need it?

Actually, I quite like systemd, but I've been bitten by its bugs many times (there's still a bug with logind after restarting dbus that delays logins and spams the system log). multipathd.{service,socket} are disabled, I'll try the rest after some hours, because I need the system at the moment.

it does not matter. Device names are not and never were stable and can change between reboots or even during system uptime (if you remove and then add back the same device).

??? Number of paths is determined by physical connectivity.

Doesn't this imply that no device is multipathed in my case?

Do not attempt to interpret names. We are speaking about driver that is called "multipath". While its purpose is indeed to work with multiple paths to a single device, this is by no means necessary for the driver to work.

There is no reason for multipath on this system, unless systemd or dracut do something weird.

Sure, systemd is the source of all evil, what else ... so change /etc/fstab to use device-independent mounts (like LABEL or UUID), reboot to verify, disable multipathd.service and multipathd.socket, disable multipath dracut module, recreate initrd and test again. It make sense to rename original initrd before so you have something to manually fall back to.

Actually, I quite like systemd, but I've been bitten by its bugs many times (there's still a bug with logind after restarting dbus that delays logins and spams the system log). multipathd.{service,socket} are disabled,

It is not clear - did you disable them now or they were disabled all the time? Do the run now (systemctl status multipathd.{service,socket})? Remember, "disabled" does not mean "cannot start".

...

I'll try the rest after some hours, because I need the system at the moment. Also, this[1] and this[2] may be relevant.

After upgrading to oS Leap, dracut boots the system normally. Apparently, the problem was due to the race between multipath and udev, but I still have no idea why my system requires multipath in the first place! -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
