I switched to software raid and kept the 3 disks as I had them into the box. Looks very similar with these bugs: https://bugzilla.opensuse.org/show_bug.cgi?id=964862 https://bugzilla.opensuse.org/show_bug.cgi?id=919284 https://bugzilla.opensuse.org/show_bug.cgi?id=1019886 You might be interested in having a try with this fix (attached): "simplify-special-case-for-md-in-69-dm-lvm-metadata.patch" This patch was originally discussed here - https://www.spinics.net/lists/raid/msg55182.html But for some reason, it is not accepted by upstream:) Hope it can help.
