| tbarron | well at least it can spell better than I: s/stupdi/stupid/ | 10:18 |
| tbarron | haobing: also, you are using the generic driver which means it is using cinder for the back end storage, so tell us in the bug which cinder back ends you are using. cinder.conf file would be helpful. | 10:19 |
| amito-infinidat | zhongjun: uploaded a new patch set for review - https://review.openstack.org/#/c/515432/ thanks (: | 10:46 |
| haobing | tbarron: the cinder use the rbd | 10:46 |
| tbarron | haobing: curious, pls. put that info in the bug too. It's almost as if your client side mount is looking at the original share instead of the new share that was created from the snapshot. If you can inspect the rados block devices on the server and match them up to the shares that manila is exporting that may help. | 10:52 |
| tbarron | haobing: all this assumes there's not some snafu with the way you are mounting from the client, double-stacked mounts or something like that. | 10:53 |

| *** belmoreira has quit IRC | 11:21 | |
| tbarron | haobing: you mention in the bug that from the viewpoint of the share server VM the original share and the new share from snapshot look OK, that their contents are different as expected. | 11:22 |
| tbarron | haobing: if you run 'sudo exportfs' on the share server do you see the right shares being exported? | 11:23 |
| *** gcb has quit IRC | 11:24 | |
| tbarron | haobing: also, what version of openstack are you running? (maybe you put it in the bug but I'm not seeing it right off). | 11:25 |
| haobing | 'sudo expotfs' is ok, | 11:25 |
| *** raissa has joined #openstack-manila | 11:27 | |

| haobing | tbarron:I use the mitaka version | 11:29 |
| tbarron | haobing: pls put the version and the 'exportfs' output in the bug if you haven't already. The reason | 11:32 |
| *** rraja has joined #openstack-manila | 11:32 | |
| *** openstackgerrit has quit IRC | 11:32 | |
| tbarron | is that these provide some suggestive evidence that what you are seeing is somehow | 11:33 |
| tbarron | due to use of generic driver with rbd. | 11:33 |
| tbarron | I could of course be wrong about this, but: a) you are using mitaka so you aren't seeing some new bug that just snuck in | 11:34 |
| tbarron | b) manila generic driver developers haven't to my knowledge tested much with rbd, they use | 11:35 |
| tbarron | default cinder back end (lvm) | 11:35 |
| tbarron | haobing: fwiw the ceph developers working with manila work on cephfs drivers (cephfs native, or now cephfs nfs) | 11:36 |
| tbarron | haobing: depending on your needs if you want to use a ceph cluster for backing storage for manila you may find those a better match. | 11:37 |
| haobing | ok,i will use the lvm to test | 11:37 |
| tbarron | haobing: great, that will isolate the problem at least! | 11:37 |
| haobing | tbarron: i tested, in the /etc/export file, share and snapshot share use the front export line as the exports | 11:45 |
| haobing | I don't know why alway use the front line as the export for share and snapshot share | 11:47 |
| tbarron | haobing: sounds like you are onto something but I'm not 100% sure what you mean. Maybe put /etc/exports in the bug and explain there? | 11:50 |
| tbarron | haobing: This now sounds like an issue that doesn't have to do with the cinder back end after all ... | 11:51 |
| tbarron | haobing: but it would be weird that the issue has been around since mitaka and not discovered yet. | 11:52 |

| haobing | tbarron:the first is the share export the secand line is the snapshot share export | 12:08 |
| haobing | if the share export in front ,the original share instead of the new share that was created from snapshot, but if the snapshot share export in front,the snapshot share instead of the original share | 12:13 |
| tbarron | haobing: You are saying that on the machine at 192.168.111.19 if you issue the cmd 'mount -t 10.254.0.14:/shares/share-9ef8702a-6b38-4ce3-bfa9-7df4a9f0e209 /mnt' and look at /mnt you see the contents of /shares/share-d7fe697f-a017-47dd-8888-69591635ec8e - right? | 12:15 |
| haobing | yes | 12:16 |
| tbarron | haobing: but if you look on that share server the two shares are different. | 12:17 |
| tbarron | haobing: so that sounds like a bug with the nfs share server. You are telling me that manila set up the exports correctly but they aren't working right. | 12:17 |
| haobing | yes,their different,one is orignal share another is snapshot share | 12:18 |
| tbarron | haobing: does that logic make sense to you? IOW, if you had manually created those exports instead of manila doing it for you, you would be seeing the same thing. manila doesn't do any magic, it just makes those shares using cinder for back end and exports them. | 12:20 |
| haobing | i do not known whether others have this problem. | 12:21 |
| haobing | no manuall create those exports, it is manila created. | 12:22 |
| tbarron | haobing: I understand that manila created the exports. I was just trying to say that when it does this it's not doing anything special. | 12:23 |
| tbarron | haobing: but now that I think of it, there could be a bug with reloading the exports after it updates the /etc/exports file | 12:23 |
| haobing | i reboot the nfs server it does not work | 12:24 |
| tbarron | haobing: and also you said 'cat /etc/exports' and 'exportfs' are consistent in the information they show you | 12:25 |
| tbarron | haobing: so that would indicate that you are not hitting a manila but where it updates the file but fails to update the kernel's view of the file | 12:27 |

| tbarron | I see you said 'exportfs is ok', meaning it has the same two entries as /etc/exports, right? | 12:33 |
| haobing | yes | 12:34 |
| tbarron | haobing: if that's true, then it sounds like an OS bug to me, BUT | 12:34 |
| tbarron | haobing: we should get the folks who work on the generic driver to look at the bug and see if they can reproduce it. | 12:34 |
| tbarron | haobing: please include OS information in the bug | 12:35 |
| tbarron | haobing: the generic driver just uses the host OS on the share server to do NFS exports, so if it sets them up correctly then after that point the exporting is out of manila's hands | 12:37 |
| haobing | the os is ubuntu 14.04.2 LTS | 12:38 |
| tbarron | haobing: As I say, please update the bug with that info. I'm not an expert on ubuntu or why you might be seeing this very strange behavior :-D | 12:40 |
