Worked on this with Hui today, this issue seems to be caused by the insufficient disk space.
I have done some investigation on e2-highcpu-8 which has 10G disk. Here is the disk free space on this instance with different kernels: * 1.9G free on / with J-gkeop * 3.2G free on / with J-gke A manual test for gf15 on e2-highcpu-8 with J-gkeop-5.15.0-1036.42 shows it will eat up all the free space very quickly and fail with the following error message in the end: growfiles(gf15): 62846 growfiles.c/2262: 78769 tlibio.c/739 write(3, buf, 4336) ret:-1, errno=28 No space left on device gf15 1 TFAIL : growfiles.c:134: Test failed Although the error message is a bit different from what we see on the J-gkeop-5.15.0-1036.42 test report: growfiles(gf15): 58147 growfiles.c/2262: 81180 tlibio.c/1007 pwrite(8, buf, 46928, 2011908881) returned=13551 growfiles(gf15): 58147 growfiles.c/1765: 81180 Hit max errors value of 1 But I think the disk space is the key. From this commit in LTP https://github.com/linux-test-project/ltp/commit/71791643b48de70cbff77ee4f9281fc6486b1814 it mentioned that: > If -i option is set to zero, some growfiles tests (e.g. gf01, > gf[10-11], gf[14-15], gf18) will grow every file size to 2G > before stopping test. And this is the command we use for gf15 test: gf15 growfiles -W gf15 -b -e 1 -u -r 1-49600 -I r -u -i 0 -L 120 -f Lgfile1 -d $TMPDIR After free up some space, make 2.2G free on / with J-gkeop this test will pass. The reason why J-gkeop used up more space then J-gke is because linux- firmware depends on linux-image-gkeop. I am not sure why we are installing linux-frmware package (which took 1G space) on this cloud kernel. If we can get rid of it this test should be able to pass. -- You received this bug notification because you are a member of Canonical Platform QA Team, which is subscribed to ubuntu-kernel-tests. https://bugs.launchpad.net/bugs/1968330 Title: ubuntu_ltp:fs:gf15 growfiles.c:134: Test failed (Hit max errors value of 1) Status in ubuntu-kernel-tests: New Bug description: growfiles(gf15): 68703 growfiles.c/2262: 77415 tlibio.c/969 writev(8, iov, 1) nbyte:24346 returned=16219 growfiles(gf15): 68703 growfiles.c/1765: 77415 Hit max errors value of 1 gf15 1 TFAIL : growfiles.c:134: Test failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1968330/+subscriptions -- Mailing list: https://launchpad.net/~canonical-ubuntu-qa Post to : [email protected] Unsubscribe : https://launchpad.net/~canonical-ubuntu-qa More help : https://help.launchpad.net/ListHelp
