zhongjun | jprovazn: hi | 08:01 |
*** Manor has joined #openstack-manila | 08:04 | |
jprovazn | zhongjun, in https://review.openstack.org/#/c/464205/4 I think closes-bug is correct: it's this patch which closes the bug | 08:05 |
zhongjun | jprovazn: oh, I am little confuse about why he separate it to two patch. | 08:07 |
*** Manor has quit IRC | 08:08 | |
*** Manor has joined #openstack-manila | 08:09 | |
jprovazn | zhongjun, the second patch enhances retry method itself, I think both ways (1 vs 2 patches) is ok | 08:11 |
zhongjun | jprovazn: This(https://review.openstack.org/#/c/465584/) could be a part of 1690159 bug patch. | 08:11 |
jprovazn | zhongjun, yes, it would be nice to reference the bug (partial-bug or related-bug), Thomas will probably have to resend it anyway becaue of your second comment, so it would be nice if he adds it | 08:13 |
*** Manor_ has joined #openstack-manila | 08:13 | |
zhongjun | jprovazn: yes, it would be nice if he adds it and I have not a very strong idea about closes-bug tag. | 08:14 |

tbarron | MVenesio: reading backlog here I saw your question yesterday regarding Ceph for manila and ganesha. | 13:35 |
tbarron | MVenesio: FYI there is ongoing work to put ganesha NFS frontend on the current manila CephFS driver | 13:35 |
tbarron | MVenesio: and the goal is to merge in Pike | 13:35 |
tbarron | MVenesio: and provide a workable fully open source driver | 13:35 |
tbarron | MVenesio: note that at this stage it will be a DHSS=False driver still | 13:35 |
tbarron | MVenesio: the outstanding reviews if you are interested: | 13:35 |
tbarron | MVenesio: https://review.openstack.org/#/c/424598/ | 13:35 |
tbarron | MVenesio: https://review.openstack.org/#/c/424605/ | 13:35 |
tbarron | MVenesio: the functional code in these reviews is pretty much done; mostly what they need before they can merge is unit test adjustments and coverage | 13:35 |

MVenesio | tbarron: thanks so much for the info, i'll check it end i'll try to test it | 20:19 |
tbarron | MVenesio: I'm on PTO through the end of next week and won't be on IRC much till then, but I'll be interested | 20:20 |
tbarron | MVenesio: is how your experiments with generic driver go as well | 20:20 |
tbarron | MVenesio: eventually we'll likely work on DHSS=True for cephfs with ganesha | 20:20 |
*** eharney has quit IRC | 20:21 | |
tbarron | MVenesio: I'm not convinced that there's a pressing need for it right away and we need to get the DHSS=False down really well first | 20:21 |
tbarron | production qualiity | 20:21 |
MVenesio | tbarron: so preparing ganesha on vms images and enabling nfs ganesha active/active for the generic driver ? | 20:21 |
tbarron | DHSS=True brings in (1) fragile networking stuff that bswartz told you about | 20:21 |
tbarron | (2) SPoF in data path | 20:21 |
tbarron | #2 is a big deal for me as I have a distro to support | 20:22 |
tbarron | both problems are probably solvable, and I have recently agreed to start looking at them in the context of generic driver too | 20:23 |
tbarron | basically, if and when we do dhss=True for cephfs+ganesha -> nfs then we'll have to cross those bridges anyways | 20:23 |
tbarron | MVenesio: no support currently for ganesha HA; first step would be ganesha active/passive; then active/active | 20:24 |
MVenesio | tbarron: sounds great | 20:24 |
tbarron | ganesha team has done ganesha active/passive outside manila context with gluster; they are looking at doing something similar for cephfs | 20:24 |
tbarron | they need to enable shared state between the ganesha instances (likely using cephfs as a "vault" for the exports and other state) | 20:25 |
tbarron | then we would somehow need to get a VIP from the ganesha instances exposed in neutron as "the" IP for export locations. | 20:26 |
tbarron | MVenesio: this is all TBD; for Pike (and maybe even Queens) it's just expose CephFS as NFS with DHSS=False | 20:27 |
MVenesio | tbarron: Yes i know the gluster stuff, but you know, having two big distribute storages to maintain is not a good deal for medium companies, even in big companies are asking us to solve everything with ceph | 20:27 |
tbarron | MVenesio: that's still a win over native CephFS driver because user VMs no longer have access to the CephFS public network | 20:27 |
tbarron | MVenesio: so infra is safer from malicious/inept tenants | 20:28 |
tbarron | MVenesio: and nowadays default neutron security rules and default anti-arp spoofing is enough for many "semi-public" private clouds | 20:28 |
tbarron | MVenesio: i.e. for private clouds that give tenants their own private nets but expect a fair amount of interaction within the cloud over floating IPs | 20:29 |
tbarron | MVenesio: yeah, my team isn't doing any active work to develop glusterfs for manila any further for just the reasons you cite | 20:30 |
MVenesio | tbarron: yes but what about Cephfs and Windows ? | 20:30 |
tbarron | MVenesio: it reportedly can be made to work (i.e., people have done it) | 20:31 |
tbarron | MVenesio: I don't know anyone working on that for manila and my team certainly is not. But this is all Open Source. | 20:31 |
tbarron | MVenesio: There can be lots of parallel efforts; if you need it, just do it :D (or if you are a customer of a distro you can lobby them to do it for you) | 20:32 |
MVenesio | tbarron: i read about it , i think is still immature, but could work in the future | 20:32 |
tbarron | MVenesio: the samba folks I've been in touch with aren't working on this actively now | 20:33 |
tbarron | MVenesio: but think it "should" work | 20:33 |
MVenesio | tbarron: Yes, first of all, i'll test the generic driver with Cinder, i think its a good approach | 20:34 |
MVenesio | tbarron: then i'll be looking for some other options, cephFS can be a really good one, and ganesha also | 20:35 |
tbarron | MVenesio: be interested in how all that goes. Good luck! | 20:35 |
MVenesio | tbarron: i'll let you know for sure | 20:35 |
tbarron | MVenesio: thanks | 20:35 |
* tbarron returns to his regularly scheduled vacation ... | 20:36 | |
