mriedemif cinder wants to enforce different rules in a v2.1 API or something, that's fine, but otherwise i think that min check has to be 0 for name so it's backwards compatible14:02
*** frickler has joined #openstack-cinder14:03
jgriffithmriedem: understood, but my point was that requiring a name is unacceptable anyway; and I believe the folks that reviewed that patch just sort of missed that nuance14:03

jgriffithxyang1: patrickeast xyang1 I'm trying to get the final version of my replication V2 patch up today.... had a question :)16:20
xyang1jgriffith: Hi16:20
patrickeastyay!16:20
jgriffithxyang1: patrickeast xyang1 I was just going through and trying to remember why I diverged from using extra-specs and moved things into the config file16:20
*** apoorvad has joined #openstack-cinder16:21
jgriffithxyang1: patrickeast smcginnis I honestly can't remember if that was a request from somebody or what :(16:21
patrickeastjgriffith: you mean the replication target configuration?16:21
jgriffithxyang1: patrickeast smcginnis but it's just as easy/reasonable I think to put it in the extra-specs16:21
jgriffithpatrickeast: correct16:21
jgriffithpatrickeast: xyang1 smcginnis so the spec I had:  replication_devices='backend=backend_name-a'....16:22
smcginnisjgriffith: I don't believe that was from any of my feedback.16:22
jgriffithor replication_devices='remote_device'={'key'='val'....}16:22
patrickeastjgriffith: not sure, imo it makes sense to be able to do either and if we have some config options we should try and get every vendor to standardize on them16:22
smcginnisAny reason to do that for an admin's benefit?16:22
jgriffithpatrickeast: well, my code right now does "either" but frankly I thought that might be bad16:23
jgriffithpatrickeast: smcginnis xyang1 the reason being is it's two support paths (actually 4)16:23
smcginnisDoes seem to me it should be one or the other to avoid confusion.16:23
jgriffithsmcginnis: that's what I was thinking16:23
jgriffithsmcginnis: patrickeast xyang1 and since both are admin functions... seems they're close enough to equivalent16:23
patrickeastjgriffith: might be easier if its the config file from the standpoint of someone wanting to go see where things are configured to replicate to without having to go look at every volume type, right?16:24
smcginnisSo if it's in the config file it would require a service restart to make any changes.16:24
smcginnisIf it's in extra-specs it can be updated at any time.16:24
patrickeastsmcginnis: good point16:24
smcginnispatrickeast: That is a good point too.16:24
jgriffith+1 to both of you... and now you see why I'm pinging you :)16:24
patrickeastlol16:24
smcginnisEasy to copy a config file between deployments.16:24
smcginnisjgriffith: ;)16:24
xyang1jgriffith: that seems fine to me16:24
jgriffithxyang1: which?  :)16:25
xyang1jgriffith: Extra specs16:25
smcginnisDo we see this changing often? If not, then I would lean toward config file.16:25
jgriffithsmcginnis: I have no idea if it will ever even get used at all16:25
smcginnisIf this is something we want more dynamic for the end user then extra specs would provide more flexibility.16:25
jgriffithlet alone change often16:25
smcginnisjgriffith: Fair point.16:25
jgriffithsmcginnis: enduser doesn't matter though... still all admin config16:26
apoorvadhgs16:26
smcginnisDon't suppose DuncanT is around to provide a service provider perspective.16:26
smcginnisjgriffith: Yeah, I meant the admin end user, not the end user end user. :)16:26
jgriffithactually... winston-d_zZZ16:26
jgriffithdang16:26
smcginnisOr any service provider for that matter.16:26
jgriffithOk... how about I propose it to use extra-spec keys and we go from there?16:27
smcginnisWorks for me.16:27

jgriffithpatrickeast: I think that might be reason enough to start by using conf16:44
jgriffithpatrickeast: and honestly it can be overridden if people want to16:44
jgriffithok... I'm going forward with the conf file16:44

*** skylerberg has quit IRC18:53
jgriffithhemna: yes, problem is erlon thinks it might be causing a problem or at least not fixing the problem18:53
hemnamaybe the wait isn't waiting/retrying long enough on super busy systems ?18:53
hemnaI think it retries 3 times18:54
hemnaI think we just bumped the backoff to 2 recently (when we were in CO)18:54
erlonjgriffith: what happens is, when you have multiple request for detach volumes, the requests wait in the lock. The request being processed clean up the system device, but, when the next request gets the lock, the first thing it does is iscsadmin --rescan, then the removed sys device is re-added18:54
jgriffithhemna: yeah18:54
hemnaheh18:54
jgriffitherlon: yep18:54
hemnaerlon, yah the rescan on detach is bad18:54
hemnaerlon, I actually have a patch waiting for the final +A18:55

hemnathat one has been waiting for a bit18:57
hemnaerlon, it should yes18:57
jgriffitherlon: try applying it and see if it fixes your case18:58
jgriffitherlon: I've been hoping it will fix an issue I'm seeing but I'm not sure... and I'm just patiently waiting18:58
erlonhemna: hmm, I tried in another way, wich didn't work, I didn't know I could remove the rescan from disconnect volume18:58
hemnaerlon, yah, just apply that patch or hack the file and remove the rescan :P18:58

jgriffitherlon: but the code has changed a bit, and it's now in the "wrong" place and actually causes issues rather than fixing them19:14
erlonjgriffith: hmm19:14
erlonjgriffith: it make more sense then to have it after issuing the 'echo 1 > /sys/block/.../remove', and the retrying until the BE remove the target19:15
openstackgerritJoel Coffman proposed openstack/cinder: Refactor to remove duplicate code  https://review.openstack.org/21382719:16
erlonwhich was what I tried to do, but, the nova code does not issue the remove_connection to the BE until it does not leave _disconnect_volume()19:17
openstackgerritJoel Coffman proposed openstack/cinder: Remove unused function volume_type_encryption_get  https://review.openstack.org/21382819:17
jgriffithYeah, so it used to be part of the delete routine19:18
jgriffitherlon: delete_volume19:18
jgriffithwe used to create targets on volume_create, and they lived until volume_delete19:18
openstackgerritJoel Coffman proposed openstack/cinder: Clean up volume_type_update method  https://review.openstack.org/21382919:18

aorourkexyang1, if you do not have create_consistencygroup_from_src implemented but you try and run cinder consisgroup-create-from-src, the CG you create goes into error state. But you can not delete that CG because it has a cgsnapshot as a dependency that needs to be delete first. Shouldn't you be allowed to delete a CG that had an error while being created?21:09
xyang1aorourke: I don't understand the dependency part21:11
aorourkexyang1, if you create a CG from a cgsnapshot, the CG has cgsnapshot_id as a FK in the database, right?21:12
xyang1aorourke: If cg depends on cgsnapshot, it should not prevent you from delete cg21:12
aorourkexyang1, cinder does not allow me to delete a CG until the cgsnapshot is deleted21:13
xyang1aorourke: You are talking about the 1st cg21:14
