multipathd segfault

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I am getting a multipathd segfault when I have more than 26 devices,
and the device names become 4 characters. (i.e. /dev/sdz is consumed
and the next device is /dev/sdaa).

I was trying to hook gdb to a core dump, but it keeps complaining that
it needs device-mapper-libs-debuginfo, which I can not find. Can
anyone point me to this?

I built multipathd with -g turned on and did not strip it. Here is the
last few lines of output when I run it as multipathd -v9 -d:
