ganso_hi, I need to get a new field I created in Share table in this line: https://github.com/openstack/manila/blob/master/manila/share/drivers/generic.py#L61615:09
ganso_vponomaryov: the only way I have figured out is to create the same field in snapshot table, since I cannot get the Share object from the DB within the generic driver15:10
ganso_vponomaryov: do you have any other suggestions?15:10
vponomaryovganso_: snapshot obj has source share as attr15:10
ganso_vponomaryov: the whole source share?15:10
vponomaryovganso_: yes15:10
vponomaryovsnapshot["share"]15:11
ganso_snapshot['share']['my_field']?15:11
vponomaryovyes15:11
ganso_nice!!! :D15:11
ganso_vponomaryov: thanks a lot :D15:11
*** esker has joined #openstack-manila15:11
vponomaryovyou have not even try it?15:11
vponomaryov=)15:11
ganso_vponomaryov: no, I have not noticed that15:11
vponomaryovganso_: little note, when you give links with line number pointer, use fixed commits as HEAD15:13
ganso_vponomaryov: how do I do that? I thought that if I do not specify the commit it is always HEAD15:14
vponomaryovganso_: branch-based can start refer to different thing very quickly15:14
vponomaryovganso_: in your case it should have been https://github.com/openstack/manila/blob/0902169a/manila/share/drivers/generic.py#L61615:15
bswartzcknight: updated code review based on our discussion, feel free to add feedback https://review.openstack.org/#/c/184544/15:15
ganso_vponomaryov: I am trying to understand how you got that link, I can't find a button to get a "tree" view15:18

vponomaryovganso_: you can get tree based on some commit from any history of commits15:30
vponomaryovganso_: either general commit history or some file history15:30
vponomaryovganso_: so, it is possible to browse whole repo on each possible state of it15:31

ganso_vponomaryov, bswartz : I am going to post a test patch for the column ID proposal, my share migration worked flawlessly with it16:03

lpetrutHi guys. I was wondering how do you handle driver specific requirements. Namely, I need pywinrm for WinRM access, but I would avoid adding it in the requirements.txt. Should I just raise a meaningfull error in case of an import exception? Or make this kind of checks in the driver initialize method?16:18
bswartzlpetrut: you should import the module in your driver init and catch the error if the library is missing, and log an appropriate message so the admin knows what he needs to isntall16:21
lpetrutgreat, thanks!16:22
bswartzalso, make sure the docs for your driver clearly spell out the additional requirements16:22
lpetrutbswartz: Also, I heard that I should ask you about the CI requirements. I was wondering about a deadline on this16:22
bswartzlpetrut: http://lists.openstack.org/pipermail/openstack-dev/2015-May/064086.html16:23
bswartzlpetrut: this is the wiki for existing drivers https://etherpad.openstack.org/p/manila-driver-maintainers16:24
bswartzif you have a new driver you may as well add it because we intend to hold all driver (existing and new) to the same standard16:25
lpetrutexactly what I needed, thanks! I plan on proposing a Windows driver, basicaly using Windows service instances. I'll most probably send an implementation first draft next week16:26
bswartzlpetrut: awesome16:27
bswartzif the driver is based on VMs running Windows, then were will you actually store the data? will cinder be used?16:28
lpetrutyep, for the beginning, I was considering having the same behavior as the generic driver16:28
lpetrutand we are considering adding scale-out cluster support in the future16:29
lpetrutcould you please take a look over the related bp? https://blueprints.launchpad.net/manila/+spec/windows-smb-support16:29
*** vponomaryov has quit IRC16:30
bswartzlpetrut: okay, we should talk about the AD domain stuff though16:30
lpetrutsure16:30
bswartzManila was explicitly designed to support creating CIFS shares inside an AD domain, but it's not particularly well tested or even well understood by most people16:30
bswartzthe NetApp driver will take parameters from the security service associated with a share network and use them to join an existing AD domain16:31
bswartzbut we don't yet have similar functionality in the generic driver16:31
bswartzObviously, a driver based on Windows should have the ability to join an user-specified AD domain16:31
lpetrutindeed. Well, this can easily be done16:33
*** jasonsb has joined #openstack-manila16:49
lpetrutas far as I see, the security service is associated with the share network. this implies having one AD controller per tenant network, right?16:49
*** timcl has joined #openstack-manila16:49
bswartzlpetrut: tenant networks can have 0 or more AD controllers16:49
bswartzwhile it might not be common, you could have 2 AD domains in the same tenant network16:50
lpetrutgot it16:50
bswartzManila would handle this by allowing the user to create 2 different share networks, each with a security service referring to one of the AD domains16:50
bswartzthen the user would specify the which share network to create the new share on, thus determining which AD domain the share will be part of16:50
lpetrutmakes sense16:51
