@bgurney-rh What are your feelings on this?

bgurney-rh commented 4 years ago

The original test script is in https://github.com/stratis-storage/stratisd/issues/1426; it needs to be tuned to avoid running into a "storm" of oom-killer events that would ensue when the filesystems are created, and the buffer/page cache usage increases, potentially to a point where the kernel starts terminating processes to avoid running out of memory.

I made a quick table of buffer/page cache usage for specific filesystem counts in the test:

50 filesystems: 20 GB cache used 100 filesystems: 40 GB cache used 500 filesystems: 200 GB cache used
