tbarronvkmc: I think you mentioned that the Ceph NFS job failed test cases pertain to IPv6?  If so,21:57
tbarronthis may be a clue: https://zuul.opendev.org/t/openstack/build/a6fa338885ab41a08daad20a403c723b/log/controller/logs/devstacklog.txt#496721:57
tbarronvkmc: we use radvd to announce the return routes to self-service tenant networks with IPv621:58
vkmctbarron, I saw the service is down21:58
vkmcbut haven't inspected too much there21:59
tbarronvkmc: lemme look at the LVM jobs, cause they should have the same need21:59
vkmctbarron, sounds good :)21:59
tbarronvkmc: also, ty for mentioning/suggesting that we may have the issue with ganesha exports and22:00
tbarronnon-default cluster name with upstream devstack as well22:01
vkmctbarron, yes... that's another thing we need to fix22:01
tbarronupstream devstack actually makes it hard to set things up like that, but I've hacked it22:01
tbarronin https://review.opendev.org/c/openstack/devstack-plugin-ceph/+/765878 and22:02
tbarronhttps://review.opendev.org/c/openstack/devstack-plugin-ceph/+/76565922:03
tbarronvkmc: working on that I saw that you are right that the Ceph community is actually saying22:03
tbarron"don't name your cluster anything but 'ceph'"22:03
tbarronvkmc: I kinda scoffed at that when you said use of non-ceph name might be a doc issue,22:04
tbarronbut apparently that is their stance !22:04
tbarronThat said, ceph-ansible still allows for use of a different name, and does this normally whe RGW is in the mix22:05
tbarronSo we still need to figure out the ganesha issue.22:05
vkmctbarron, yes... we need to change that, somehow... or at least properly document it22:05
gouthamrdoes the name of the cluster matter as much as the path to the conf file?22:06
tbarronGood news is that the problem reproduces in devstack where it should be easier to play with the exports format than in frozen container code.22:06
gouthamrnice ^22:06
vkmctbarron, not sure how many people tinkered with those ceph-ansible values22:06
tbarrongouthamr: dunno for sure, by convention (like ansible) the path to the conf file and the names of the cli9ent keys refelct the "cluster name"22:06
vkmcgouthamr, we need to test that22:07
tbarronThe last may not have any real meaning beyond these except that it also shows up in the systemd units (at least in ubuntu)22:07
tbarronso you have to override those as well if you change it.22:08
tbarronby "the last" I mean the "cluster name" which the ceph people are trying to say is not useful any more, so they want to always let it be "ceph" and22:09
tbarrontell you not to use the "--cluster" arg to ceph cmd any more.22:09
tbarronDifferent clusters named "ceph" will have different fsids and if the same hardware hosts both they'll run in separate containers.22:10
tbarron^^ That's my understanding of ceph community's position going forwards.22:10
tbarronBut their apis have more tentacles and are more slimy than manila's.22:11
tbarronOur little zprillas were went to API finishing school despite having been called skunks by some in the ceph community.22:12
gouthamr:'D22:13
vkmcyeah, it seems an accurate outcome based on other design decisions that have been made22:14
