Conversation

Previous code will add `ndevices` simulated drive into device list which make each replica go with one real drive and ndevices simulated drive. Those simulated drives are identified as FAST, meta/log were on them. Due to the very limited size of simulated drive, we can hit size limit in long running test. Fixing by honor input from hs_repl_test_common. After this fix, if only one drive passed in for a replica of test_raft_repl_dev, that drive will be used as FAST. All services will be started on that real drive. Signed-off-by: Xiaoxi Chen <xiaoxchen@ebay.com>

When using the write_on_leader() for long running tests, it is very possbile a leader switch happens during the test. Previous implementation the new leader(prvious follower) will not able to aware the role change and pick up to do more write. Signed-off-by: Xiaoxi Chen <xiaoxchen@ebay.com>

I believe this PR will be very helpful for raft_repl_dev UT. pls proceed and finish this PR, thanks |

There was a problem hiding this comment.
now we have three use cases, priority-wise:
- UT specificly passed dev_list, if not there,
- --device_list from input, if not there,
- m_token.name_ which equeals to test_binary, name.
Can we put it as in comment at line: 178 (the start_homestore api), so that it can be friendly to us after a few month when we look back and don't need to scratch our head wondering why?

This PR has been idle for one month. Do we still want to merge this? |
this PR is very helpful to make repl_dev unit test stable in github CI. after this , we can enable @xiaoxichen pls go ahead and complete this PR when you get cycle. |
