Lastly, I'd like to ask that you take the opportunity to test with the latest openSUSE Factory kernel running 3.10-final. 12.3 used the 3.7 kernel since it was the most recent release going into the beta cycle and we've seen a bunch of btrfs fixes since that release.
I look forward to your feedback and the opportunity to improve btrfs for the 13.1 release and future releases.
How about starting ~10 procs creating numerically incrementing files with sizes @ 128 768, 1K, 16k, 256k 32M 512M. Start them all, let them run for a few minutes, then kill power. Maybe put a fixed pattern in each so you can also verify the contents...?? Of some of those files, have them seek to end and write 1 byte. Are the remaining blocks zeroed when you read them? Are the files stored sparse? What is the optimal I/O size? (testing w/dd for example using iflags=direct oflags=direct Whats the maximum throughput? ...compared to theoretical? Seems like those would test a few things... Can they have ACL's (presuming yes), add accels to some and see if a power hit results in any problems there? Just a few "gentle" things to try out a FS. ??? -- To unsubscribe, e-mail: firstname.lastname@example.org To contact the owner, e-mail: email@example.com
