Hi Abhay,
Would it be possible for you to change the namsepace.t and trash.t (as discussed in IRC) tests to work with both endian architectures?
Both failures seem to be linked to the issue that SuperFastHash() provides different values on little & big endian architectures. You could do something like `lspcu | grep "Little Endian" to determine the endianess and this value can be used to have the right behavior in tests.
Please feel free to let me know if you need more assistance in fixing both namespace.t and trash.t tests.
Regards,
Vijay

Hi,
I am working on Glusterfs v4.1.1 for Ubuntu 16.04 on big endian architecture. After successful build and running the test cases, I encountered a test case failure. The test case is:-
· ./tests/basic/namespace.t
In the test case ./tests/basic/namespace.t, a NAMESPACE_HASH is generated after calling a SuperFastHash() function on the corresponding folder names. This hash differs on big endian and little endian architectures. Therefore, I have changed the code accordingly. Although there is another subtest in this test which fails with the following error:-
TEST 30 (line 119): Y check_samples CREATE 1268089390 /namespace3/file patchy0
getfattr: /d/backends/patchy0/namespace3/file: No such file or directory
As seen above, the error is occurring because the folder /d/backends/patchy0/namespace3/ doesn’t contain “file”. However, I resolved this subtest by changing the folder to /d/backends/patchy6/namespace3/ where “file” is actually present.
But same is not the case for little endian architectures where the test case passes without any changes.
The type of filesystem /d/backends is “ext4” and there is enough space allocated to the directory.
Therefore, could you please provide me with some more insight as to why is this happening?
Thanks and Regards,
Abhay Singh
