| UnitTest | src/vos/vea/tests/vea_ut src/eio/smd/tests/smd_ut Look at the DAOS-1246 and include all unit tests for NVMe | ||
| Exiting Functional Test | Identify and run existing functional test cases with NVMe | Manual Test is in Progress, once it's done will update the test case information here. | |
| I/O | Create the Pool with small NVMe size (0/1G/48G) | Write/Read data (<4K) 1B/1K/4K [Random/Sequential] and make sure it does not use NVMe Write/Read data with non standard sizes 4025,259K,1.1M,30.22M [Random/Sequential] and make sure it does not use NVMe | For second case, data sizes can be generated random instead of predefined fixed size. |
Write/Read data (>4K) 1M/16G [Random/Sequential] and make sure it use NVMe Write/Read data with non standard sizes 4025,259K,1.1M,30.22M [Random/Sequential] and make sure it does not use NVMe | For second case, data sizes can be generated random instead of predefined fixed size. | ||
| Create the Pool with Large NVMe size (1TB/2TB) | Write/Read data (<4K) 1B/1K/4K [Random/Sequential] and make sure it does not use NVMe Write/Read data with non standard sizes 4025,259K,1.1M,30.22M [Random/Sequential] and make sure it does not use NVMe | For second case, data sizes can be generated random instead of predefined fixed size. | |
Write/Read data (>4K) 1M/16G/1TB [Random/Sequential] and make sure it use NVMe Write/Read data with non standard sizes 4025,259K,1.1M,30.22M [Random/Sequential] and make sure it does not use NVMe | For second case, data sizes can be generated random instead of predefined fixed size. | ||
| Unaligned IO | Try using the offset from API or use the core Python API to modify the existing Array and read through. | The test code daos_run_io_conf.c will be doing similar thing so worth to use same. | |
| I/O with Server/System restart | Create the Pool with small NVMe size (0/1G/48G) | Write/Read data (<4K) 1B/1K/4K | Write the data/ Stop Server/Start Server/Read data back and check data integrity. |
| Write/Read data (>4K) 1M/16G | Write the data/ Reboot the node/ Start server/read data back and check data integrity. | ||
| Create the Pool with Large NVMe size (1TB/2TB) | Write/Read data (<4K) 1B/1K/4K | Write the data/ Stop Server/Start Server/Read data back and check data integrity. | |
| Write/Read data (>4K) 1M/16G | Write the data/ Reboot the node/ Start server/read data back and check data integrity. | ||
| Create the Pool with Large NVMe size (1TB/2TB) | Write single IOR data set, Read single IOR data set | Kill the server while IO is doing Write and start the server. IO should continue after server start? Do the same when read is in progress | |
| Create the Pool with Large NVMe size (1TB/2TB) | Write multiple IOR data-sets, Read multiple IOR data-sets, Read-Write Together | Kill the server while IO is doing multiple write and start the server. IO should continue after server start? Do the same when Multiple Read is in progress. | |
PMDK may have some API to get the allocated but it wont be easy to use as it is. There is Pool Query which will provide in future which can be track the size to verify memory leak. We may need fault injection layer to control the PMDK transaction with server start/stop. Example: 1> Create 3G pool 2> Write 1G data and before it goes for transaction commit shutdown the server. 3> Next server start it should claim the full 3G space | |||
| Re-written data fetch validation | Write the data on NVMe >4K Re-write using the same array with small size ~1-2 bytes which will go through SCM. Do this and change ~100 bytes with the different data Do fetch which will combined the record and verify it. Do the similar thing like writing small data set to SCM and overwrite large data to NVMe, and validate the content. | When overwriting the data will be kind of new epoch entry getting created. But it will use the old data set and update the new bytes value only. During fetch Epoch will aggregated and provide the result with modified bytes. | |
| Re-written data fetch validation | Write the data on SCM <4K Extend the data set using the same array with larger size >8K which will go through NVMe Do this and repeat for few times with the different data Fetch the dataset which will combined the records, Verify all the old+new records. | ||
| Verify there is no leak after PMDK Transaction | PMDK may have some API to get the allocated but it wont be easy to use as it is. There is Pool Query which will provide in future which can be track the size to verify memory leak. Example: 1> Create 3G pool 2> Write 1G data and before it goes for transaction commit shutdown the server. 3> Next server start it should claim the full 3G space | We may need fault injection layer to control the PMDK transaction with server start/stop. | |
| Large number of Pool with Server/System restart | Create the large number of pools (10000) with different NVMe sizes | Write mixed data across all the pools (1K/4K/1M/1T) | Write the data/ Stop Server/Start Server/Read data back and check data integrity. |
| Write the data/ Reboot the node/ Start server/read data back and check data integrity. | |||
| Pool Capacity | Create the NVMe pool size 1GB | Write IO > 1GB which should failed with ENOM SPACE | |
| Create pool same size as NVMe drive | Write IO till pool is getting filled up, once the Drive is full it should not allow to write more data with ENOM_SPACE | ||
| Create the pool with maximum of NVMe size and delete. | Run this in loop for example if NVMe is 2TB, create the pool size of 1TB, 500GB, 500GB, delete all the pools. Do this in a loop and make sure pool creation work and size can be reclaimed. | ||
| Pool Extend | Extend the single pool to multiple targets | Create the few data set on single pool (1K/4K/1M/1T). Extend the pool to all target at once. | Verify the data integrity after pool extension done |
| Create the few data set with single pools (1K/4K/1M/1T). Extend the pool target one by one, for example 6 server so pool created with 2 and start extending the pool to 4 servers one by one | Verify the data integrity after pool extension done | ||
| Extend the multiple pools to targets | Create the few data set on different pools (1K/4K/1M/1T). Extend the pools to all target at once. | Verify the data integrity after pool extension done | |
| Create the few data set with single pools (1K/4K/1M/1T). Extend the pool target one by one, for example 6 server so pool created with 2 and start extending the pool to 4 servers one by one | Verify the data integrity after pool extension done | ||
| Pool Exclude | Exclude the target from Pool | Create the few data set on different pools (1K/4K/1M/1T). Exclude the pools from all target at once. | Add target to pool and verify the data integrity after pool excluded |
| Create the few data set on different pools (1K/4K/1M/1T). Exclude the pools from all target one by one. | Add target to pool and verify the data integrity after pool excluded | ||
| NVMe rebuild | Single drive Rebuild | Use 4 server minimum and load 50% of Drives. | Shutdown the single server or Eject and make sure the data is getting rebuilt on another NVMe drive |
| Object | Create the large number of object update/fetch with different Object ID in single pool created on NVMe | Verify the objects are getting created and data are not corrupted | |
| Create the large number of object in multiple pool created on NVMe (Pools size 1M/1G/1T) | Verify the objects are getting created and data are not corrupted | ||
| Performance | Compare the DAOS performance | Run performance utility (TBD) without DAOS and IOR with DAOS. | Performance measurement for Read/Write and IOPS. |
| daos_perf test | Run daos_perf test with VOS and with DAOS | ||
| Metadata | Create the pool of small size (NVMe size 1G) | Run Mdtest to fill the Pool with metadata | After fool it should not allow any data to be written on pool Even if NVMe has the space ? |
