Hello.
I just upgraded my Kernel to: 4.14.70-1-lts | device-mapper 2.02.181-1 | multipath-tools 0.7.7-1 After that multipathd started to giving the log: // device-mapper: ioctl: ioctl interface mismatch: kernel(4.37.0), user(4.39.0), cmd(16) It was working great on my ex kernel "4.14.30-1-lts" with | device-mapper 2.02.177-5 | multipath-tools 0.7.6-1
Also I tried multipath git version but nothing change.

I think the problem related to device-mapper and my device mapper Build Date: 2018-08-01 19:05 UTC = https://www.archlinux.org/packages/core/x86_64/device-mapper/
Do I need to compile device mapper git version or what should I do?


Hi

Can you pastebin how is your package linked while being compiled (gcc log) and
how is then used runtime  (ldd) ?

It seems the code was linked with different .so library then it's using in runtime.

libdm  is supposed to handle all kernel versions.


Regards

Zdenek
