Hi, I'm running RBD kernel client on two machine. One is running 3.6-rc2 and the other is running Ubuntu's 3.2.0. Ceph is 0.48.1 running on Ubuntu precise. The 3.6.2-rc gives this : [145442.041999] libceph: osd2 10.208.3.71:6800 socket error on read [146343.040635] libceph: osd2 10.208.3.71:6800 socket closed [146343.042026] libceph: osd2 10.208.3.71:6800 socket error on read [147244.040626] libceph: osd2 10.208.3.71:6800 socket closed [147244.042035] libceph: osd2 10.208.3.71:6800 socket error on read [148145.040622] libceph: osd2 10.208.3.71:6800 socket closed [148145.041960] libceph: osd2 10.208.3.71:6800 socket error on read Ubuntu is spitting out : [137386.490990] libceph: osd1 10.208.3.70:6803 socket closed [137386.491730] libceph: osd1 10.208.3.70:6803 connect authorization failure [138287.151376] libceph: osd1 10.208.3.70:6803 socket closed [139187.486980] libceph: osd1 10.208.3.70:6803 socket closed [139187.487720] libceph: osd1 10.208.3.70:6803 connect authorization failure [140088.141914] libceph: osd1 10.208.3.70:6803 socket closed [140988.478992] libceph: osd1 10.208.3.70:6803 socket closed [140988.480565] libceph: osd1 10.208.3.70:6803 connect authorization failure [141889.155024] libceph: osd1 10.208.3.70:6803 socket closed [141889.156123] libceph: osd1 10.208.3.70:6803 connect authorization failure This doesn't seem to affect operation at all AFAICT. Also the osd is _always_ the same in the message (but different between machines.) I also don't think it's a connectivity issue because osd0/1 are on one box and osd2/3 on another. So any connectivity issue hitting osd2 should hit 3 as well, same for 0&1. Any idea of what to look for ?
