OK. I have not given complete information. It does not fail indefinably. I can umount the fs immediately after the failure. Only the test fails because fsck sees a mounted fs. There must be a bit of a delay in the umount that causes the problem. > > They both work for me on a quick test, anyway, on a .38 > kernel. Problem existed for me in .37 as well. I don't think it is kernel (or fs) related. I think it is a system problem, but I fall short of ideas how to fix it. > > What are you using for your partitions under test? > Currently, I have /dev/sda5,6,7,8. I used to work with LVM, but lstat64 didn't like the /dev/mapper links, so I switched to raw partitions. Although I was puzzled that xfstests could not work over LVM partitions It could when I changed lstat64 to stat64, but then I changed it back thinking it was causing my problems. > -Eric > >> Thanks, >> Amir. > > -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
