Hi all, We've been waiting to see if other people who couldn't make on Sunday would also do some testing. That hasn't happened, so a few words on my impressions on the test day are appropriate indeed. First of all not many people really did some testing. We didn't expect many people to participate, but the 3 people who did (many thanks to them!) were the bare minimum we anticipated. This was probably caused by the following: - SSD caching may need more explanation, not many people understand what it is and what the benefits are - Because it's hard to change an existing partition to a 'bcached' partition, it's not really tempting to test (there's a blocks utility under development that may help, currently backup-restore is the only way). - Not many people have the required resources available to do testing. Even when testing in a VM not many people have the required 10GB available (The requirements could be lowered top about 6GB, so that might help) - Installing F20 as requested in the prerequisites was harder to the testers than we anticipated. Specifically planning a specific partition layout in Anaconda requires a lot of attention (I could upload a VM image somewhere to facilitate that). About the testing itself: - the alignment of the tools (bcache-tools, kernel, util-linux and dracut) is really good now, people were able to do the testcases (1.A and 1.B) without a hitch. - nobody tested the LVM integration (testcases 2.A and 2.B), so no test results on that part. - Unfortunately kernel 3.11.4 (which was the latest version on Sunday) exhibited a bug during stress testing (https://bugzilla.redhat.com/show_bug.cgi?id=1018615), but that bug is supposed to be fixed in kernel 3.11.5 which was released later this week. So I think SSD Caching (using bcache) is in a good shape, but I would like to encourage people to do some more testing. Of course other feedback is also appreciated.
Good work, and thanks for the detailed summary! Regards, Hans -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
