Details

mdadm raid arrays with a gpt partition table on them do not get partuuid/partlabel entries in /dev/disk/by-{partuuid,partlabel} created by udev.

The fix is rather simple: 63-md-raid-arrays.rules needs to copy the following two lines from 60-persistent-storage.rules:

# by-partlabel/by-partuuid links (partition metadata)
ENV{ID_PART_ENTRY_SCHEME}=="gpt", ENV{ID_PART_ENTRY_UUID}=="?*", SYMLINK+="disk/by-partuuid/$env{ID_PART_ENTRY_UUID}"
ENV{ID_PART_ENTRY_SCHEME}=="gpt", ENV{ID_PART_ENTRY_NAME}=="?*", SYMLINK+="disk/by-partlabel/$env{ID_PART_ENTRY_NAME}"
This task depends upon

Any update on this? Its a two-line change and I even provided a patch!

This should really be patched upstream

And in fact, the by-partuuid part was fixed in https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/commit/?id=3c9b46cf9ae15a9be98fc47e2080bd9494496246, which should land in v4.2
