Currently I have finished implementing it and testing now. I sent a patch to an aufs user since he requested this feature strongly and propsed as tester. So I guess he and I are testing it now. Will you join this test? Of course, it is a test and I never recommend you to use it for production use. > Is there any tool that allows merging the two branches in the upper > read-write branch, so that we can safly remove the corrupted branch to > be reformatted ? I know it should be easy to implement (maybe the > snapmerge script that comes with unionfs can be used). Unfortunately, I don't have such tool currently. Also I think that it is worth to try the snapmerge script in unionfs. While I am not sure, here is an idea. # mount -t aufs -o br:/rw:/ro none /aufs (some works) # mount -o remount,prepend:/new_rw,xino=/new_rw/xino,mod:rw=ro /aufs (continue working) # mount -t aufs -o ro,br:/rw=ro:/ro none /aufs2 # cp -ru /aufs2 /aufs # umount /aufs2 > Our application uses O_DIRECT (as a compile time flag) for performance > reasons. We can disable O_DIRECT to be able to use aufs, although it > would be very nice if aufs supported O_DIRECT (Junjiro was asking if > that was neccessary). Ok. I will append it to my work-list. I am afraid reacing it will take a longer time since some aufs users have some troubles now. You might know it if you read this ML. If you have a simple test case for O_DIRECT which I can use testing aufs, please send me. Junjiro Okajima ------------------------------------------------------------------------- Take Surveys.
