You are aware that you complained about released out-of-tree module code not compiling against latest upstream *release candidate* kernel code? Maybe you should simply use a released kernel? Or better yet, an enterprise distribution? If you insist on using git checkouts, you need to be either fit to fix things yourself, get external help to fix it, or live with the occasional breakage. Besides, it *does* work. If it breaks again, we fix it. Obviously we cannot fix it before upstream breaks, right? So we need to notice the breakage, then fix it, and then publicize those fixes. Each of these steps can be delayed... > where else would one magically obtain it?

We very much try to keep the out-of-tree code in sync with the in-tree version. Obviously, as development happens out-of-tree still, *and* the out-of-tree code works with all kernel versions back to 2.6.5 (or so), the out of tree code necessarily has to be different. > Should I be worried about DRBD in general? Sure. If you are involved with high availability or data integrity, you should always worry. That's part of taking it seriously. In part it also comes down to: do you trust us to know what we are doing. If not, we even use DRBD? > Or at least 8.4.2?

I'd say (not only) the community is just conservative, and rightly so. We still have customers that use 0.7, which really is not even close to the 8 series in "correctness", even; but, "never change a running system"... There is a huge number of installations still on the 8.0 branch, which has not received changes or bugfixes for a long time already. Because, 8.3 received new features. Which sometimes also is the source of "unstable-ness". Now that 8.3 is the current stable branch, I expect most conservative people to settle on that for the time being. Or follow 8.4, for new deployments, performance improvements, or new features. Or because 8.3 at some point will stop compiling against your favorite git checkout of the upstream kernel. Of course, you could also just contact LINBIT, if you need specific help with DRBD or high availability issues. -- : Lars Ellenberg : LINBIT | Your Way to High Availability : DRBD/HA support and consulting http://www.linbit.com DRBD® and LINBIT® are registered trademarks of LINBIT, Austria. __ please don't Cc me, but send to list -- I'm subscribed _______________________________________________ drbd-user mailing list drbd-user@lists.linbit.com http://lists.linbit.com/mailman/listinfo/drbd-user
