Hardware Configuration
| Item | Description |
|---|---|
| Fabric | Preferred PSM2 |
| Number of Servers | 2 to 6 |
| Drives per servers | We have few system which has multiple drives so run first IO tests with 2 NVMe per servers |
| Number of Client | 4 to 8 and use 32 process per CN. |
| daos_nvme.conf | Use the default option for now. [Nvme] |
Tests:
| Test | Condition | Data Input | Comments |
| UnitTest | src/vos/vea/tests/vea_ut and src/eio/smd/tests/smd_ut | ||
| I/O | Create the Pool with small NVMe size (0/1G/48G) | Write data (<4K) 1B/1K/4K and make sure it does not use NVMe | |
| Write data (>4K) 1M/16G and make sure it use NVMe | |||
| Create the Pool with Large NVMe size (1TB/2TB) | Write data (<4K) 1B/1K/4K and make sure it does not use NVMe | ||
| Write data (>4K) 1M/16G/1TB and make sure it use NVMe | |||
| I/O with Server/System restart | Create the Pool with small NVMe size (0/1G/48G) | Write data (<4K) 1B/1K/4K | Write the data/ Stop Server/Start Server/Read data back and check data integrity. |
| Write 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 data (<4K) 1B/1K/4K | Write the data/ Stop Server/Start Server/Read data back and check data integrity. | |
| Write 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 | Kill the server while IO is running and start the server. IO should continue after server start? | |
| Create the Pool with Large NVMe size (1TB/2TB) | Write multiple IOR data-sets | Kill the server while IO is running and start the server. IO should continue after server start? | |
| 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 Pool from target | 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 | ||
| Object | Create the large number of object 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 | ||
| 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 ? |
