Hi Neil,

The /dev/disk/by-path/* symlinks are not created for ATA devices in systems using

systemd v182+, so mdadm cannot use them in case of policies and udev rules
(mdadm -If --path=...)

What do you think - what should be used instead? The symlinks from /sys/block/* ?

I am using a patched udev from systemd daemon collection v204, it
still has "by-path" symlinks setup in the persistent storage rules.
Similarly upstream systemd daemon collection v204 also sets up
"by-path" symlinks in the persistent storage rules.

What is your udev rules config? are any of persistent storage rules
overridden? or not waiting for udev to settle? maybe the "builtin"
command "path_id" not returning / detecting the paths of ATA devices
in question?

The /dev/disk/by-path/* symlinks have not been created for ATA devices in systemd since v182:
