Use choose rather than chooseleaf here due to https://tracker.ceph.com/issues/62213

I'm not sure why this one needs 4 hosts, 8 osds per host. 2+2 should probably be a normal host chooseleaf rule, right?

isn't it supposed to be 4 host 1 osd? so it will simulate full host shutdown?

Right, so step chooseleaf indep 4 type host

Ah,
'choose indep 4 type host',
'choose indep 1 type osd',
is almost correct, but you should use step chooseleaf indep 4 type host instead. Using two choose steps instead of a single chooseleaf step actually has different behavior once OSDs get marked out.

@athanatos @neha-ojha I added some code to thrash hosts, so the thrasher will be able to thrash the entire osds under one host |

@NitzanMordhai there are a few suspect jobs in the latest teuthology run as analyzed by @ronen-fr :
And two more with slightly different Tracebacks but similar problems:
These failures don't happen deterministically, so it might be worth running several of these "workloads/ec-rados-plugin=xxx} " tests multiple times to ensure they're passing. |

To simulate real world maintanace, we will usualy shut down hosts and not just osd the following commit will add host thrasher option to Thraser, when thrash_hosts is True we won't thrash osds one by one, we will choose entire host and thrash all the osds under that host.

Looks like this one was merged a little early before a second round of QA could be reviewed. @NitzanMordhai can you take a look at https://tracker.ceph.com/issues/65517? |
