Hi Sage & List I understand this is probably a hard question to answer.
I mentioned previously our cluster is co-located MON’s on OSD servers, which are R515’s w/ 1 x AMD 6 Core processor & 11 3TB OSD’s w/ dual 10GBE. When our cluster is doing these busy operations and IO has stopped as in my case, I mentioned earlier running/setting tuneable to optimal or heavy recovery operations is there a way to ensure our IO doesn’t get completely blocked/stopped/frozen in our vms? Could it be as simple as putting all 3 of our mon servers on baremetal w/ssd’s? (I recall reading somewhere that a mon disk was doing several thousand IOPS during a recovery operation) I assume putting just one on baremetal won’t help because our mon’s will only ever be as fast as our slowest mon server? Thanks, Quenten
