I hastily redrafted my content 11:29:24 <oneswig> OK well I don't think there's much to cover this week, let's do AOB 11:29:28 <oneswig> #topic AOB 11:30:23 <oneswig> I'm getting to the bottom of doing SR-IOV on top of 2-port bonded NICs, am hoping to write up the findings within a week or two 11:31:07 <oneswig> should be interesting but the question of "was it worth the trouble" is harder to answer 11:31:24 <janders> in case of fitting the winch and radios on the 4wd - for sure! :) 11:31:29 <noggin143> we're looking into a tough ceph issue from last week, current suspicion is that LZ4 compression may have problems 11:31:46 <noggin143> but nothing for sure 11:31:54 <oneswig> noggin143: ouch. How do you isolate that? 11:32:19 <noggin143> had to rebuild the osd-maps. Dan will write up something once the analysis is complete 11:32:35 <oneswig> sounds interesting, thanks. 11:32:48 <oneswig> Do you know how the seastar messenger work is progressing btw? 11:33:36 <noggin143> I don't know the details, was due to get an update at cephalacon but it got cancelled (South Korea not the best place to visit at the moment)) 11:34:29 <oneswig> I'm having not very much success in finding the point in the chain where packets are being discarded, when it appears to be set up for end-to-end flow control. Very niggly. 11:36:10 <oneswig> OK, any more AOB to share? 11:36:28 <janders> nothing from my side 11:36:39 <verdurin> Nor from me. 11:37:57 <oneswig> In which case I shall return to my dark cave of LAGs, SRIOV and troubleshooting packet drops... 11:38:08 <oneswig> thanks all, see you next week verdurin 11:38:11 <oneswig> #endmeeting
