Ah, some days I need more coffee than others :/ As it is, that test does not fail on my DAX testing on RAM disks. ISTR it failing up until recently, though. Yeah: Last login: Tue Nov 17 08:45:55 2015 from 192.168.1.103 $ cd ~/src/xfstests-dev; sudo mkfs.xfs -f /dev/ram0 ; sudo xfs_admin -U generate /dev/ram0 ; sudo MOUNT_OPTIONS="-o dax" ./check -g auto SECTION -- xfs FSTYP -- xfs (debug) PLATFORM -- Linux/x86_64 test4 4.3.0-dgc+ MKFS_OPTIONS -- -f -bsize=4096 /dev/ram1 MOUNT_OPTIONS -- -o dax /dev/ram1 /mnt/scratch .... generic/083 2s ... 1s _check_xfs_filesystem: filesystem on /dev/ram1 is inconsistent (c) (see /home/dave/src/xfstests-dev/results//xfs/generic/083.full) _check_xfs_filesystem: filesystem on /dev/ram1 is inconsistent (r) (see /home/dave/src/xfstests-dev/results//xfs/generic/083.full) .... But as I ran earlier today when testing the ENOSPC fix: PLATFORM -- Linux/x86_64 test4 4.4.0-rc2-dgc+ MKFS_OPTIONS -- -f -bsize=4096 /dev/ram1 MOUNT_OPTIONS -- -o dax /dev/ram1 /mnt/scratch .... generic/083 1s ... 2s .... So I'm seeing that the current 4.4-rc2 + my local dev tree patches appear to have fixed whatever was causing generic/083 to fail here... What version of xfsprogs are you using, Ross?
