| Description |
|
Shutting down a copytool (by writing shutdown to mdt.lustre-MDT0000.hsm_control and waiting for mdt.lustre-MDT0000.hsm_control to contain stopped) takes about 8 seconds. In sanity-hsm.sh's copytool_cleanup() this is done is series for each MDT. Since copytool_cleanup() is called 95 times (with MDSCOUNT=4) this means that we waste about 95 * 3 * 8 == 2280 seconds per test run when compared to parallel shutdown. |
