* [Test+Libfix] Add test to add brick followed by remove brickkshithijiyer2021-01-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | Test case: 1. Create a volume, start it and mount it to a client. 2. Start I/O on volume. 3. Add brick and trigger rebalance, wait for rebalance to complete. (The volume which was 1x3 should now be 2x3) 4. Add brick and trigger rebalance, wait for rebalance to complete. (The volume which was 2x3 should now be 3x3) 5. Remove brick from volume such that it becomes a 2x3. 6. Remove brick from volume such that it becomes a 1x3. 7. Wait for I/O to complete and check for any input/output errors in the logs of both the I/O and rebalance logs. Additional library fix: Adding `return True` at the end of is_layout_complete() to return True if no issues found in layout.

* [LibFix] Optimizing setup_volume api.srijan-sivakumar2020-12-181-2/+2
| | | | | | | | | | | | | | | | Currently the setup volume API is calling the get_volume_info to obtain the volume information to check if the said volume already exists. Internally the get_volume_info would have to parse the complete xml dump received for volume info. Instead of that one can invoke the get_volume_list which would mean reduced effort put into parsing the output received as volume name is the only important factor in this check inside setup_volume.

* [LibFix] Adding retry for start_glusterdsrijan-sivakumar2020-11-271-4/+11
| | | | | | | | | | | | Issue: Glusterd start fails after repeated start and stop. ( Due to the cap on maximum of 6 starts of the service within an hour ) Fix: Hence it is prudent to add the retry option similar to that of restart_glusterd so as to run `systemctl reset-failed glusterd` on the servers.

To solve this problem we need the libraries for: 1. Logging memory and CPU utilization 2. Checking for OOM killer on gluster processes 3. Checking for memory leaks 4. Checking for cpu usage spikes 5. Wrapper functions in base class to make development easy 6. Compute statistics of usage Detailed description: ===================== We have already added script to log CPU and memory usage through patch [1]. In this patch we would be using patch [1] and building logic to process the CSV files generated by the script which would help us to achieve the following: 1. Checking if there are memory leaks or CPU spikes 2. Computing statistics of memory and CPU usage Function sets added: ~~~~~~~~~~~~~~~~~~~~ Set 1 - Functions to perfrom logging using script ------------------------------------------------- Public functions: 1. check_upload_memory_and_cpu_logger_script() 2. log_memory_and_cpu_usage_on_servers() 3. log_memory_and_cpu_usage_on_clients() 4. log_memory_and_cpu_usage_on_cluster() 5. wait_for_logging_processes_to_stop() 6. kill_all_logging_processes() Private functions to support public functions: 1. _start_logging_processes() 2. _process_wait_flag_append() Set 2 - Functions to check for OOM killers ------------------------------------------ Public functions: 1. check_for_oom_killers_on_servers() 2. check_for_oom_killers_on_clients() Private functions to support public functions: 1. _check_for_oom_killers() Set 3 - Functions to check for memory leaks ------------------------------------------- Public functions: 1. check_for_memory_leaks_in_glusterd() 2. check_for_memory_leaks_in_glusterfs() 3. check_for_memory_leaks_in_glusterfsd() 4. check_for_memory_leaks_in_glusterfs_fuse() Private functions to support public functions: 1. _perform_three_point_check_for_memory_leak() Set 4 - Functions to check for cpu usage spikes ----------------------------------------------- Public functions: 1. check_for_cpu_usage_spikes_on_glusterd() 2. check_for_cpu_usage_spikes_on_glusterfs() 3. check_for_cpu_usage_spikes_on_glusterfsd() 4. check_for_cpu_usage_spikes_on_glusterfs_fuse() Private functions to support public functions: 1. _check_for_cpu_usage_spikes() Set 7 - Functions to calculate stats ------------------------------------ Public functions: 1. compute_data_usage_stats_on_servers() 2. compute_data_usage_stats_on_clients() Private functions to support public functions: 1. _get_min_max_mean_median() 2. _compute_min_max_mean_median() Set 6 - Wrapper functions added to base class --------------------------------------------- 1. start_memory_and_cpu_usage_logging() 2. compute_and_print_usage_stats() 3. check_for_memory_leaks_and_oom_kills_on_servers() 4. check_for_memory_leaks_and_oom_kills_on_clients() 5. check_for_cpu_usage_spikes_on_servers() 6. check_for_cpu_spikes_on_clients() Set 7 - Other generic functions ------------------------------- Public functions: 1. create_dataframe_from_csv() Third party libraries added to glusto-tests through patch: 1. Numpy(It is being used in file_dir_ops.py but it's installed on clients and not on management node.) 2. Pandas 3. Statistics How do I use it in my testcase? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ For example if we take the testcase to Check the server side memory leak with fuse mount, we would need to perfrom the below steps: 1. Create Disperse volumes 2. Fuse mount on the client 3. Start creating files in 1000's in parallel with 3. Create directories in 1000's in parallel 4. Do linux untar and wait for completion 5. Watch the memory usage on the server side and check for the OOM killers. Here steps 1-4 would be as usual, for step five what we need to do would be after step 2 we would need to start logging memory usage with the below code: ``` proc_dict = cls.start_memory_and_cpu_usage_logging() assertIsNotNone(proc_dict, <Error message>) ``` Once step 4 is complete we would need to wait for the logging process to stop with the below code: ``` ret = wait_for_logging_processes_to_stop(proc_dict, cluster=True) assertTrue(ret, <Error message>) ``` And lastly to check for memory leaks and OOM killers we would need use the below code: ``` ret = cls.check_for_memory_leaks_and_oom_kills_on_servers() assertTrue(ret, 'Memory leaks or OOM killer found') ``` NOTE: Interval and count of function start_memory_and_cpu_usage_logging() and gain of check_for_memory_leaks_and_oom_kills_on_servers() would need tweaking on a case by case scenario.

* [Libfix] Change logic to restart glusterdkshithijiyer2020-08-311-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: bring_bricks_online() method uses direct invocation of `service glusterd restart` at line 212. However due to change in behaviour of glusterd through patch [1] and [2] if glusterd is restart more than 6 times in an hour it goes into failed state which has to be reset using the `systemctl rest-failed` command. This causes a random failures as shown below: ``` 2020-08-25 18:00:51,600 INFO (run) root@rhs-vm24.blr.com (cp): service glusterd restart 2020-08-25 18:00:51,601 DEBUG (_get_ssh_connection) Retrieved connection from cache: root@rhs-vm24.blr.com 2020-08-25 18:00:51,830 INFO (_log_results) ^[[34;1mRETCODE (root@rhs-vm24.blr.com): 1^[[0m 2020-08-25 18:00:51,830 INFO (_log_results) ^[[31;1mSTDERR (root@rhs-vm24.blr.com)...

* [Libfix] Add interval_check for monitor_heal_completionBala Konda Reddy M2020-08-211-3/+6
| | | | | | | | | | | | | | | | | | | | | | | Adding a parameter `interval_check` will ease the user and help in the reducing the waiting time for heal in scenarios. By default, ls -l <brickpath> | grep -ve "xattrop-" | wc -l is checked for every 2 minutes. Problem: I have 100 files that needs to be healed, after 2 minutes. suppose there are only 2/3 files that needs to be healed. With the existing approach the next check will wait for whole 2 minutes even though the files would have healed by 10 seconds after previouscheck. Solution: Giving an option for the user to check at which interval to check for the files that needs to healed, we can reduce the unnecssary waiting time. It won't affect the existing cases as the interval_check is defaults to 120. Change-Id: Ib288c75549644b6f6c94b5288f1c07cce7933915 Signed-off-by: Bala Konda Reddy M <bala12352@gmail.com>
* [LibFix] Fix code to avoid failuresayaleeraut2020-08-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Description: Earlier, on running a test script which calls get_volume_type(), the test script displayed below failure message in glusto logs: "INFO (get_volume_type) Failed to find brick-path 10.70.47.44:/bricks/brick2/testvol_distributed_brick0// for volume testvol_distributed" - even though the brick-path was present in the volume. Checked by directly calling the function as well: >>> from glusto.core import Glusto as g >>> from glustolibs.gluster.volume_libs import get_volume_type >>> ret = get_volume_type('10.70.47.44:/bricks/brick2/vol1-b1/') >>> print ret Distribute >>> ret = get_volume_type('10.70.47.44:/bricks/brick2/vol1-b1//') >>> print ret None Observed that the issue occurs if an extra "/" is present at the end of the brickdir_path(str) parameter passed to the function.

* [LibFix] Add encoding type to get_fattr()sayaleeraut2020-08-121-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the get_fattr() function returns the xattr value in the hex encoding format. Adding the option to add/specify other encoding types, i.e. text and base64, where hex will be the default encoding format. Reason - When the xattrs are custom set through mountpoint, it becomes easier to test if the value is correct by using the "text" encoding. Example - >>> ret = get_fattr(host, fqpath, fattr) >>> print ret 0x414243 >>> ret = get_fattr(host, fqpath, fattr, encode="text") >>> print ret "ABC" The value "ABC" is easily readable as opposed to 0x414243 when performing a test.

* [Libfix] Fix UnicodeDecodeError in get_fattr()kshithijiyer2020-08-111-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Some testcases fail with UnicodeDecodeError when the framework is run using python3. This happens becuase the get_fattr() command returns non-unicode output which leads to data.decode() used in subprocess.Popen to fail. This isn't the case in python2 as it doesn't bother about encoding and dumps whatever is the output back to the management node. ``` gfid = get_fattr(brick_tuple[0], brick_path + '/' + direc, 'trusted.gfid') /root/glusto-tests/tests/functional/dht/test_dht_create_dir.py:127: /usr/local/lib/python3.8/site-packages/glustolibs_gluster-0.22-py3.8.egg/glustolibs/gluster/glusterfile.py:113: in get_fattr rcode, rout, rerr = g.run(host, command) /usr/local/lib/python3.8/site-packages/glusto-0.72-py3.8.egg/glusto/connectible.py:132: in run stdout, stderr = proc.communicate() /usr/lib64/python3.8/subprocess.py:1024: in communicate stdout, stderr = self._communicate(input, endtime, timeout) /usr/lib64/python3.8/subprocess.py:1904: in _communicate stdout = self._translate_newlines(stdout, self = <subprocess.Popen object at 0x7f22b4e2f490>, data = b'\xber\t\nO\xebO\xee\xa4\x9c\xc4L\xac\x1cj\xd5', encoding = 'UTF-8', errors = 'strict' def _translate_newlines(self, data, encoding, errors): data = data.decode(encoding, errors) E UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbe in position 0: invalid start byte /usr/lib64/python3.8/subprocess.py:901: UnicodeDecodeError ``` Solution: Change get_fattr() command to return xattr value in hex to avoid UnicodeDecodeError error from Popen.

* [Libfix] Add parameter for volume create onlyBala Konda Reddy M2020-05-182-7/+30
| | | | | | | | | | | | | | | | | | | | | | | | | Problem: Currently setup_volume in volume_libs.py and gluster_base_class.py are to create volume and start it. There are tests, where only volume_create is required and if the test has to run on all volume types. Any contributor have to do all the validations which are already implemented in setup_volume and classmethod of setup volume in the gluster_base_class to their test. Solution: Added a parameter in the setup_volume() function "create_only" by default it is false, unless specified this paramter setup_volume will work as it is. similarly, have added a parameter in classmethod of setup_volume in gluster_base_class.py "only_volume_create", here also defaults to false unless specified. Note: After calling "setup_volume() -> volume_stop" is not same as just "volume_create()" in the actual test.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Below command to 'pkill pidof glusterd' is not right, as it is not getting the pidof glusterd. eg: cmd = "pkill pidof glusterd" ret, out ,err = g.run("10.20.30.40", cmd, "root") >>> ret, out, err (2, '', "pkill: only one pattern can be provided\n Try `pkill --help' for more information.\n") Here command is failing. Solution: Added `pidof glusterd` which will get proper glusterd pid and kill the stale pid after glusterd stop failed. cmd = "pkill `pidof glusterd`" ret, out ,err = g.run("10.20.30.40", cmd, "root") >>> ret, out, err (1, '', '') Note: The ret value is 1, as it is tried on a machine where glusterd is running. The purpose of the fix is to get the proper pid. Change-Id: Iacba3712852b9d16546ced9a4c071c62182fe385 Signed-off-by: Bala Konda Reddy M <bala12352@gmail.com>
