Hello! Sorry if it's the wrong list, it is referred to by multipath-tools without saying it's "devel", so I presume user questions are okay…? How to debug a lack of devices in `multipath -l` and `… -ll` outputs? I'm studying `multipathd -dv5` logs, but it's not at all clear to me as to what to look for. At $WORK I'm trying to replace the older Ubuntu shipped multipath-tools with the upstream one. Then, given a system with the upstream `multipath-tools` preinstalled and `multipathd` running, none of the `multipath -l` or `multipath -ll` show output. Then, if I downgrade `multipath-tools` to the one from Ubuntu repository and restart `multipathd`, devices do appear. Then it gets weird: if I upgrade `multipath-tools` back to the latest one upstream, and reboot, devices are still there! It starts working! At this point I found the `/etc/multipath/wwids` which might be the reason. I presume `multipathd` puts devices there under some conditions. But where can I see how it decides whether to work with devices or to ignore them? I'm looking through -v5 startup logs when it's working and when it doesn't, there's a lot of output, but it's hard to `diff` the older (working) and the newer (not working) output — a lot of style changes. Entries I find suspicious are repeated in both cases. I figured, it might ask here for pointers, is there something specific to look for? -- dm-devel mailing list dm-devel@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/dm-devel
