Hi all, unfortunately nfs05.sh fails for some reason (the only test which fails). It works on various filesystems: nfs05 1 TINFO: using not default LTP netns: 'tst_ns_exec 31811 net,mnt' nfs05 1 TINFO: initialize 'lhost' 'ltp_ns_veth2' interface nfs05 1 TINFO: add local addr 10.0.0.2/24 nfs05 1 TINFO: add local addr fd00:1:1:1::2/64 nfs05 1 TINFO: initialize 'rhost' 'ltp_ns_veth1' interface nfs05 1 TINFO: add remote addr 10.0.0.1/24 nfs05 1 TINFO: add remote addr fd00:1:1:1::1/64 nfs05 1 TINFO: Network config (local -- remote): nfs05 1 TINFO: ltp_ns_veth2 -- ltp_ns_veth1 nfs05 1 TINFO: 10.0.0.2/24 -- 10.0.0.1/24 nfs05 1 TINFO: fd00:1:1:1::2/64 -- fd00:1:1:1::1/64 tst_device.c:96: TINFO: Found free device 0 '/dev/loop0' tst_supported_fs_types.c:90: TINFO: Kernel supports ext2 tst_supported_fs_types.c:55: TINFO: mkfs.ext2 does exist tst_supported_fs_types.c:90: TINFO: Kernel supports ext3 tst_supported_fs_types.c:55: TINFO: mkfs.ext3 does exist tst_supported_fs_types.c:90: TINFO: Kernel supports ext4 tst_supported_fs_types.c:55: TINFO: mkfs.ext4 does exist tst_supported_fs_types.c:90: TINFO: Kernel supports xfs tst_supported_fs_types.c:55: TINFO: mkfs.xfs does exist tst_supported_fs_types.c:90: TINFO: Kernel supports btrfs tst_supported_fs_types.c:55: TINFO: mkfs.btrfs does exist tst_supported_fs_types.c:90: TINFO: Kernel supports vfat tst_supported_fs_types.c:55: TINFO: mkfs.vfat does exist tst_supported_fs_types.c:157: TINFO: Skipping exfat as requested by the test tst_supported_fs_types.c:120: TINFO: FUSE does support ntfs tst_supported_fs_types.c:55: TINFO: mkfs.ntfs does exist tst_supported_fs_types.c:90: TINFO: Kernel supports tmpfs tst_supported_fs_types.c:42: TINFO: mkfs is not needed for tmpfs nfs05 1 TINFO: === Testing on ext2 === nfs05 1 TINFO: Formatting ext2 with opts='/dev/loop0' nfs05 1 TINFO: Mounting device: mount -t ext2 /dev/loop0 /tmp/LTP_nfs05.BXqm4Onw7z/mntpoint nfs05 1 TINFO: timeout per run is 0h 10m 0s nfs05 1 TINFO: mount.nfs: (linux nfs-utils 2.6.2) nfs05 1 TINFO: setup NFSv4, socket type tcp nfs05 1 TINFO: Mounting NFS: mount -v -t nfs -o proto=tcp,vers=4 10.0.0.2:/tmp/LTP_nfs05.BXqm4Onw7z/mntpoint/4/tcp /tmp/LTP_nfs05.BXqm4Onw7z/4/0 nfs05 1 TINFO: start nfs05_make_tree -d 10 -f 30 -t 8 tst_test.c:1558: TINFO: Timeout per run is 0h 11m 00s nfs05_make_tree.c:211: TPASS: 'make' successfully build and clean all targets Summary: passed 1 failed 0 broken 0 skipped 0 warnings 0 nfs05 1 TPASS: test finished nfs05 2 TINFO: Cleaning up testcase nfs05 2 TINFO: === Testing on ext3 === ...
