*** gouthamr_ is now known as gouthamr01:13
zhongjun_gouthamr_: hi gouthamr01:14
gouthamrzhongjun_: i wanted to check with you about the huawei replication patch..01:14
gouthamrzhongjun_: https://review.openstack.org/#/c/331586/ <- this one.01:14
zhongjun_gouthamr: I saw it.01:15
*** yangyapeng has joined #openstack-manila01:16
zhongjun_gouthamr: about the part of replicate snapshot?01:16
gouthamrzhongjun_: the main concern was about not implementing the snapshot interfaces... when we implemented replication, there was a design aspect regarding snapshots being replicated as well.01:16
gouthamrzhongjun_: we assumed that a snapshot would be part of the filesystem or in some place where your replication technology is aware of; in terms of copying it over to the destination.01:18
gouthamrzhongjun_: apparently, that's not true in case of the huawei nas backend?01:18
zhongjun_gouthamr: yes, I checked with zhaohua, that's not true in case of the  huawei nas backend.01:20
gouthamrzhongjun_: oh. zhaohua did mention that you'd be talking to the product team regarding that limitation.. we probably need to discuss what's the best way to cover this.01:22
gouthamrzhongjun_: your backend can take a snapshot on the 'active' replica when it is being replicated?01:22
*** tellesnobrega_af is now known as tellesnobrega01:27
zhongjun_gouthamr: I need to check it. as far as I know, In cinder, we only implement replicate volume, not implement replicate snapshot.01:29
*** ganso has quit IRC01:31
gouthamrzhongjun_: yes, please. We can discuss this further if you like.. If your backend supports taking snapshots, and creating replicas, things can go wrong when creating snapshots after replication begins.. if you don't implement the create_replicated_snapshot interface, snapshots will not work. Maybe we can live without snapshot replication, but the creation still can be fixed, i guess.01:33
*** akshai has joined #openstack-manila01:33
zhongjun_gouthamr: If only implement the replicate share. Is manila framework code need to be changed?01:33
gouthamrzhongjun_: not really, but snapshots will not work on some backends and they'll work on some others. that's not a pleasant experience...01:34
*** akshai_ has joined #openstack-manila01:35
gouthamrzhongjun_: In case of NetApp cDOT and ZFS, create_replicated_snapshot is identical to create_snapshot.. so, it might just work with huawei too..01:36

gouthamrhey guys, some review attention on this please: https://review.openstack.org/#/c/343649/ <-- fix needs to be backported to stable/liberty where it currently matters to stop failing the coverage-db job17:29

tpsilvagouthamr: Hi Goutham17:36
gouthamrtpsilva: Hi Tiago. Wassup?17:37
tpsilvagouthamr: regarding the driver filter/goodness weigher patch, do you want me to add the documentation on the same patch?17:37
tpsilvagouthamr: or can it be pushed later?17:37
gouthamrtpsilva: you can add documentation in a separate patch... you could assign the doc bug that gets raised onto yourself and add it after this merges..17:38
gouthamrtpsilva: i guess it will help reviewers understand the feature better if it goes into the same patch though, no pressure :)17:39
tpsilvagouthamr: well, it's just a matter of copying the documentation from cinder17:42
tpsilvagouthamr: I'll check that17:42
tpsilvagouthamr: thank you!17:42

tpsilvagouthamr: do I need to create this doc bug?17:54
gouthamrtpsilva: no, please add a DocImpact on the commit message, it will create a bug for you when it merges..17:54

FransUrboI'm getting "Unauthorized: The request you have made requires authentication" when trying to create a share. And the share ends up in "error" status.19:47
FransUrboMy manila.conf: http://bayour.com/misc/manila.conf.txt19:47
FransUrboThe log also say: "Creation of share instance 2fe81679-7f0c-4d40-8301-0cb6c6254515 failed: failed to get share server."19:48
FransUrboI'm at a loss to where the problem is. As in, what part is failing to authenticat what?19:49
FransUrboMy admin-openrc file is fine, I've successfully used it for every other service (Neutron, Nova, Cinder etc, etc).19:49
bswartzFransUrbo: It works exactly the same way cinder does (if you have any experience with that)19:50
FransUrboVery little..19:50
bswartzyou need some env variables set19:50
FransUrboAny other than:19:51
FransUrbo# echo $(env | grep ^OS | sed 's@=.*@@')OS_USER_DOMAIN_NAME OS_IMAGE_API_VERSION OS_PROJECT_NAME OS_IDENTITY_API_VERSION OS_PASSWORD OS_AUTH_URL OS_USERNAME OS_PROJECT_DOMAIN_NAME19:51
bswartzyeah those are the right noes19:51
bswartzright ones*19:51
bswartzif you're getting authentication problems I'd suspect one of those variables is wrong19:51
FransUrboI'm thinking Manila is having problem with some authentication to some of the other services (Neutron, Nova etc)..19:51
FransUrboNo, those are correct. As I said, I've used that successfully with every other service.19:52
bswartzalthough the log message you point to suggests something else is wrong19:52
FransUrboI know :(19:52
bswartzah I know what you mean19:52
bswartzthere are some tokens in the manila.conf file for nova/cinder/neutron19:52
bswartzthose are need if you use generic driver19:53
bswartzneeded19:53
bswartzmy recommendation is that you use the LVM driver not the generic driver19:53
FransUrboOk.19:53
FransUrboYou men the "enabled_share_backends = lvm"?19:54
FransUrbo*mean*19:54
*** cknight has quit IRC19:55
bswartzfor that option, "lvm" is just the name of a config section19:55
FransUrboRight..19:55
bswartzyou'd need to create a [lvm] section with all the appropriate config options for that driver19:56
bswartzhttp://docs.openstack.org/mitaka/config-reference/shared-file-systems/drivers/lvm-driver.html19:56
FransUrboYeah, I had that before. But got other problems..19:58
FransUrboAnyway, I get "Filter CapabilitiesFilter returned 0 host(s)" and then "Failed to schedule create_share: No valid host was found.".20:00
FransUrboBut that's actually EXACTLY what I get from Cinder when trying one of my "own" drivers, so I'm thinking Cinder is faulty here..20:00
FransUrboThanx for the pointers! I'll be back if I still have problems after fixing Cinder.20:03
