Hi all, as promised several times, here's now a patchset with all the patches queued up in my SLES repository. The first bits are pretty much uncontroversial (I hope), mainly fixes etc. Next there are some systemd updates, setting dependencies and such. The _really_ important patch is multipathd: skip uninitialized devices during reconfiguration which basically is the cause for all the missing wwid issues we've seen. So I wonder if we shouldn't just do away with all the tweaks we've accumlated so far and see if that patch isn't sufficient. According to Kay Sievers it should... Next is a general overhaul of the 'cookie' mechanism; Ben, Mike, mind to have a look here? It _seems_ reasonable enough, but it would be nice to have additional confirmation for that. Finally there are patches which probably require some more discussion: - Asynchronous configuration: Do not call 'reconfigure' directly, but rather set the daemon_status to 'configuration' and defer the actual work to the main thread. This allows us to decouple it from the CLI call, and we won't run into any udev/systemd timeout issues when booting on large installations - Lock pushdown: I remember to have sent this patch already at one point, but it got rejected. So I try again :-) With this patch the big vector lock is pushed down to the areas where we actually need it, making the entire system running far smoother during booting or failover in large instances. We have been using this patch since SLE12 GA, ie for over two years now. And seem to have ironed out all issues with it. The entire patchset can be found at: github.com:/hreinecke/multipath-tools.git branch sles-resync As usual, comments and reviews are welcome. Patches are based upon the latest git, including Bens patchset.
