Sorry. I wasn't very clear with what I was asking for. Unless I'm
missing something here, if multipathd is trying to use /var/run, that
means that when the multipathd binary was compiled, it was compiled on a
machine where /var/run was not a symlink.
So, I'm wondering where your multipathd binary got compiled. Are you
using a packaged version from a distribution like RHEL, SLES, Fedora,
Ubuntu, etc? Did you compile it yourself?
When I run multipathd under strace, I can see:
openat(AT_FDCWD, "/run/multipathd.pid", O_WRONLY|O_CREAT, 0644) = 3
The multipathd binary I'm using was compiled on a machine where /var/run
is a symlink to /run, so multipathd directly uses /run, instead of using
/var/run. I'm assuming that whatever machine your multipathd binary was
compiled on, /var/run was a directory. Do you know if that's possible?
