rrajaaovchinnikov: hi!15:40
aovchinnikovrraja: hi15:41
*** dmk0202 has quit IRC15:42
rrajaaovchinnikov: about using nfs-ganesha to export share, have you looked at https://github.com/openstack/manila/blob/master/manila/share/drivers/ganesha/__init__.py (manila's ganesha library)15:42
aovchinnikovrraja: yes, sure15:43
*** ChanServ changes topic to "Midcycle Meetup Today 1200-2000 UTC | https://etherpad.openstack.org/p/newton-manila-midcycle | OpenStack Shared File Systems | Manila"15:43
rrajaIIRC we create an export block for each manila share access rule, dynamically export it using dbus and persist the export block in a file.15:43
aovchinnikovyes, but this is still a workaround15:44
rrajait's not ideal. but that's what we had to do back then.15:44
rrajado you intend to modify the same export block?15:44
aovchinnikovin an ideal world one would simply modify an export block in a single config and update ganesha15:45
rrajayeah, right.15:45
aovchinnikovI've added a possibility to choose between modifying an existing block, then removing and readding it and creating multiple exports15:46
aovchinnikovthe first approach causes interruption15:46
aovchinnikovthe second seems to break manila's conception of share locations a little15:46
aovchinnikovbecause each client will see different pseudo path15:47
aovchinnikovso I thought that it will be  better to let the end user decide what is worse for her15:47
rrajaso the issue is the dbus interface does not have something like modifyblock (got only add/remove).15:50
aovchinnikovyes15:50
aovchinnikovand dbus seems to be the only way to talk to ganesha15:51
aovchinnikovso no way to modify an existing export15:51
rrajawe'd raised the issue before but it was not elevated to high priority IIRC. we can check with ganesha folks again.15:52
aovchinnikovthat would be great!15:52
rrajaaovchinnikov: would you mind summarizing your issue in openstack-dev ML?15:53
aovchinnikovok, no problem, I'll write about my experience to openstack-dev15:54
rrajathanks!15:54
rrajadid you reuse the existing ganesha library or did you writeup something better from scratch?15:55
aovchinnikovI've ended up writing something similar from scratch15:55
aovchinnikovcan't say that it is better15:56
rrajacool!15:57
aovchinnikovanyway, it is almost ready to get submitted for review15:57

vkmchey all, do Manila has integration with the openstack client?20:44
dustinsvkmc: Not last I checked20:49
vkmccool20:49
vkmcand another thing20:49
vkmcis there a way to list mapping between nova instances and manila shares?20:49
dustinsAs in which shares are mounted to which nova instances?20:50
vkmcyes20:50
dustinsI also don't think that's possible20:51
dustinsSince there isn't an explicit command to mount a manila share to a nova instance20:51
dustinsThe mounting of shares is done through the instances itself20:52
dustinsThere were some talks a while ago to have an API call similar to "cinder attach" that would do so, but there are some interesting issues with that20:53
vkmcI see...20:57
vkmcI thought that manila access-allow was some sort of cinder attach20:57
vkmcand hence, we had in the control database that information20:58
dustinsvkmc: not exactly, access-allow just puts together the specified rules to make the instance have access to the share20:58
dustinsThe mounting is still done by the instance itself20:59
vkmcI see, thanks dustins20:59
vkmcwhich brings me another question20:59
dustinsvkmc: No problem!20:59
vkmchow do you mount cephfs?20:59
vkmclike... you need to install any dependency in the nova instance?20:59
dustinsYes, you need to have either the ceph-fuse client (recommended) or use the kernel client (which is not as recommended)21:00
dustinsAnd also do the requisite plumbing to grant the access from the Ceph cluster to the instance21:00
dustinsIt's unfortunately not as "plug and play" as I'd like21:01
vkmchmm21:02
vkmcseems we could use some sort of manila-image-elements? xD21:02
vkmcthanks for all the info21:03
dustinsIt can make the scenario testing of such drivers a bit of a pain, because I would have to create the instance, do the plumbing to make it authenticate to the Ceph servers, and then install the ceph-fuse client21:03
dustinsBefore I could actually test what I was after :)21:03
dustinsvkmc: It's indeed possible!21:03
vkmcI certainly don't know which are the steps needed to grant access from the Ceph cluster to the instance... time to RTFM21:04
vkmcread the fancy manual21:04
dustinsThe stuff specific to the CephFS Native driver is here: http://docs.openstack.org/developer/manila/devref/cephfs_native_driver.html21:04
