vkmcgouthamr, wanna hear your feedback later about access lists00:20
vkmcin the spec we put openstack share access create and openstack share access delete00:20
vkmcthe verb used should be allow or deny00:21
vkmcI completely missed that00:21
vkmcshould we update it to allow/deny or we stick with create/delete?00:21
vkmcIMHO allow/deny are more accurate but I wanna hear other people feedback00:21
tbarronallow/deny are historically what we have said but there are no deny rules, deny just deletes an allow rule :)01:05
vkmcwell yes01:06
vkmcbut semantically01:06
tbarroni'm not suggesting that we change from allow/deny01:06
vkmcif you have allow, you have deny01:06
tbarronbut it's confusing to people (like me) who came from packet filter world where there were explicit deny rules too01:07
tbarronbasially there were bit maps with  two senses, allow and deny01:07
tbarronbut we have only allow and implicit deny if there ain't a rule allowing it01:08
tbarronand the verb deny means delete a rule01:08
* tbarron is going home now, just wanted to cause a little trouble on the way out01:08
vkmchahaha01:09
vkmcthere no deny, there is "not allow"01:09

tbarronmnaser: manila community meeting is a 1500 utc today in #openstack-meeting-alt so I added it to the agenda12:34
mnasertbarron: cool thanks, i'll be in the channel, feel free to highlight me :)12:34
tbarronmnaser: seems OK to me offhand but worth getting general awareness, etc.12:34
mnaseryeah, i might actually have some manila-image-elements clean ups too, there's a bunch of stuff we can probably get away with -- i'll see how far i can get12:35
tbarronmnaser: excellent, we'll tag you when this comes up in the meeting12:43

noonedeadpunktbarron: hey, I have a question regarding cephfs_ganesha_server_ip. So it seems that it's used for reaching server via ssh. In case export config lies not in rados (but in local filesystem) and there are several ganesha servers, seems like only one will be properly configured and reached19:03
tbarronnoonedeadpunk: maybe we need a list for that config option, we had really only envisioned one ganesha server (or, later running DHSS=true with a dynamically launched ganesha server per tenant, but that wouldn't use this option)19:05
*** jmlowe has quit IRC19:05
tbarronnoonedeadpunk: do you have separate file systems behind the ganesha servers?19:06
noonedeadpunkI think they 're gonna be the same... I'm just thinking about some ha19:06
noonedeadpunkbut just strated thinking about it actually19:07
noonedeadpunkI thought that both of them should use the same cephfs pool and in terms of failure of one ns server another one was able to pick up stuff19:08
noonedeadpunkhm, launching ganesha per tenant sound also interestingly actually...19:09
noonedeadpunkso in this case ganesha binary should be installed on the manila-share host?19:09
tbarronnoonedeadpunk: jeff layton has work to run multiple ganesha daemons active-active with the same filesystem but I dunno that the default shipping ganesha stuff that ships today can do  that19:10
tbarronnoonedeadpunk: in any case i started this journey when it couldn't, so downstream we run it active-standby under pacemaker-corosync purposes for HA19:11
tbarronnoonedeadpunk: only one ganesha is actually running but there are three controllers where it is "queued up"19:12
noonedeadpunkI'm thinking about active/backup at the point with keepalived19:12
tbarronnoonedeadpunk: so yeah, we run it on the manila-share host and run manila-share the same way19:12
noonedeadpunkyes, that is exactly what I want to implement at this point19:12
noonedeadpunkoh, ok, so cephfs_ganesha_server_is_remote is false for this usecase?19:13
tbarronnoonedeadpunk: yes19:13
noonedeadpunkand with remote it's not so trivial...19:14
tbarronnoonedeadpunk: we also want to support the external ceph cluster case where ganesha is running externally as well, and19:15
tbarronthe external cluster is responsible for ganesha HA.  OpenStack/manila don't own the  problem in that case.19:15
tbarronand for that currently the external cluster must present a VIP or some such for the config connection.19:16
tbarronpresent itself as one thing.19:16
tbarronnoonedeadpunk: and then as I mentioned there's the future DHSS=True case, but work needs to be done such that19:17
tbarronthe external Ceph cluster plus ganesha has an api so we can spawn up new ganeshas per tenant and then19:17
noonedeadpunkyeah, I see19:17
tbarronnetwork them (we're thinking via kuryr) back into the tenant's own network19:18
noonedeadpunksounds even more complicated19:18
noonedeadpunkbut interestesting19:19
tbarronnoonedeadpunk: the work to do it, yes.  but if we can do it then life for the deployer will actually be pretty easy19:19
