https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244048 --- Comment #15 from Kirk McKusick <mckusick@FreeBSD.org> --- (In reply to ml from comment #14) Can you successfully run these operations on stable/11? Or put another way, do these problems only show up when you try to run on stable/12? It would be helpful to find out if the problem is fixed when running on stable/13 as that would let us review changes made in the development of stable/13 to find the likely culprit. If is not fixed in stable/13 but it works in stable/11, then we will know that the breakage happened during the development of stable/12. To be reliably able to track down the problem, we need a disk image of the filesystem that experiences the problem (i.e. the UFS+SU filesystem on which you are having the problem) along with a set of commands that when run on that image cause the problem to happen. I realise that you do not know exactly what the parameters are for triggering the problem. I would suggest saving an image and then use script(1) to record the set of commands that you run trying to cause the hang. When you eventually get a hang you will presumably know how to reliably recreate it. Hopefully you can narrow it down to something where you do not need to run too many commands to trigger the problem. You can then gzip(1) the disk image and let us know where we can pick it up along with the set of cammands that cause the hang. We can then verify that we can reproduce the hang and if so finding a fix can proceed. -- You are receiving this mail because: You are the assignee for the bug.help
