bswartztbarron: she did argue that it was generally useful, but I found the argument to be unconvincing00:43
*** caowei has joined #openstack-manila00:44
bswartzwhen we got into use cases, I didn't hear any problems that all_squash could solve which couldn't be solved some other way00:45
bswartzTo me it feels like a case of trying to take every tool that exists in Linux's NFS implementation and exposing it through Manila. I've resisted that from the beginning.00:47
*** gouthamr has quit IRC01:03
tbarronwell almost all implementations support it; the back ends in the room all said they could do it except one; we've supported and designed for capabilities that only one or actually none yet (i think of some of the replication values) can actually support01:18
tbarronso I guess we disagree on the value of *squash, fair enough01:19
tbarronbut my impression was that most of the folks at the PTG were convinced of its value; I put that in the minutes, no one sought to correct01:19
*** gouthamr has joined #openstack-manila01:25
bswartzWell I have an obvious bias, given that we're discussing a feature NetApp doesn't support01:35
bswartzHowever, my logic is that -- if it was really a valuable feature, we'd support it, because NetApp has a _lot_ of NFS customers01:35
*** zhongjun_ has joined #openstack-manila01:35
bswartzThe vision for Manila has always been to intentionally expose less than everything that's possible on each backend01:36
bswartzWe don't aim for the lowest common denominator, but we only aim above it when there's a good use case01:37
*** wes_dillingham has joined #openstack-manila02:15
zhongjun_I thought we agree with all resource could have its own metadata02:21
tbarronwell I think zhongjun_ convinced all but one of the people at the PTG that this was a good use case :)02:25
*** kaisers_ has joined #openstack-manila02:27
zhongjun_so I am confused again02:28
tbarroni'm signing off for tonight; zhongjun_ we did agree that in general resources can have their own metadata; I'm just02:28
tbarrontrying to find a way to keep the core opensource manila strong, so that when we identify02:28
tbarronfeatures that are worth while we put our energies into developing them for the community02:28
tbarronbswartz and I have an honest disagreement about whether the *squash features fall into the02:30
tbarroncategory of features worth developing.02:30
tbarronin manila proper.02:30
*** kaisers has quit IRC02:30
tbarronI might be wrong, but I thought he was in a minority of 1 on the issue.02:31
zhongjun_tbarron:  "we did agree that in general resources can have their own metadata"  so could we just agree with implement the metadata stuff in Rocky?  " I'm just trying to find a way to keep the core opensource manila strong" This is a total different feature, It is worth to discuss it, but it don't have any relationship with metadata?02:43

tbarronzhongjun_: I think I've been clear, we can proceed with the access rule metadata spec.11:38
tbarronzhongjun_: the open issue is whether access rule metadata should be used to implement *squash capabilities11:39
tbarronzhongjun_: for clouds that need to implement these11:39
*** e0ne has quit IRC11:40
zhongjun_tbarron:  Thanks tom.  The access rule metadata shouldn't be used to implement *squash capabilities11:40
tbarronzhongjun_: my position is that it should not, that we should treat *squash the way we do other capabilities11:40
tbarronzhongjun_: bswartz's position if I understand him is that this is not a useful capability to have11:41
tbarronzhongjun_: in core manila; if it were useful netapp would have implemented it; so that if one11:41
tbarronzhongjun_: wants to implement this it must be done by use of metadata or some other extension11:41
tbarronzhongjun_: mechanism outside core open source upstream manila11:42
tbarronmy position is that there are clear use cases for all_squash, e.g. when one has a share with11:43
*** e0ne has joined #openstack-manila11:44
tbarronan anonymous ftp directory or the like11:44
tbarronand there is a need to force the uid from a set of external clients to a known, safe uid that11:45
tbarroncan nonetheless write to that directory11:46

zhongjun_tbarron: so, you fears that vendors may use metadata as a way to put *squash feature in.  If the access rule metadata shouldn't be used to implement *squash capabilities, we can continue to do the access rule metadata spec.11:58
tbarronzhongjun_: we can continue to do the access rule metadata spec11:59
tbarronzhongjun_: and my fear is less about back end vendors (they are generally motivated to *want*11:59
tbarronzhongjun_: capabilities to be recognized by open source manila) than by non-open-source forks12:00
tbarronzhongjun_: of manila12:00
zhongjun_tbarron:   thanks, let's continue to do the access rule metadata spec12:01
*** erlon has joined #openstack-manila12:10
zhongjun_tbarron: Could you add some comments on the access rule metadata spec when you have free time.  It would be more clear and more useful for tracing history.12:12
zhongjun_tbarron: Thanks in advance12:12
