openstack | Launchpad bug 1737724 in Cinder "FC attachment issue" [Undecided,New] | 01:11 |
*** yangyapeng has joined #openstack-cinder | 01:12 | |
mriedem | i'm kind of in the middle of fixing some other bugs associated with the new attach flow in nova | 01:13 |
mriedem | is there something specific i need to look at? | 01:13 |
tommylikehu | I am wondering how you correctly handle and save this connection info at nova side:) | 01:13 |
*** psachin has joined #openstack-cinder | 01:13 | |
*** s-shiono has joined #openstack-cinder | 01:14 | |
mriedem | i don't see errors in the c-api, c-vol or n-cpu logs here http://54.209.116.144/93/526893/2/check/kaminario-dsvm-tempest-full-FC/82abd60/logs/ | 01:14 |
tommylikehu | mriedem, cause cinder save the connection info in the form of simple key/value strings and it could not meet the requirement of arrays | 01:14 |
mriedem | nova is not sending connection_info dicts to cinder | 01:15 |
mriedem | those come *from* cinder | 01:15 |
tommylikehu | mriedem: I thought you would save them | 01:15 |
tommylikehu | here is the root cause: INSERT INTO attachment_specs (created_at, updated_at, deleted_at, deleted, `key`, value, attachment_id) | 01:15 |
tommylikehu | VALUES ("2017-12-11 01:49:36", "2017-12-11 01:49:36", "", 0, "wwpns", ["21000024ff34c92d", "21000024ff34c92c"], "e3aab3b7-539c-45c9-855b-ec7aeb908f21")'] [parameters: {'attachment_id': 'e3aab3b7-539c-45c9-855b-ec7aeb908f21', 'deleted': 0, 'created_at': datetime.datetime(2017, 12, 12, 9, 2, 8, 449122), 'updated_at': None, 'value': [u'21000024ff34c92d', u'21000024ff34c92c'], 'key': u'wwpns', 'deleted_at': | 01:15 |
tommylikehu | None}] | 01:15 |
mriedem | that's coming from the host connector | 01:16 |
mriedem | nova asks os-brick for the host connector | 01:16 |
mriedem | and passes that to cinder | 01:16 |
mriedem | in the PUT /attachments call | 01:16 |
mriedem | cinder stores the connector dict values in the attachment_specs table | 01:16 |
mriedem | as key/value pairs | 01:16 |
mriedem | is there a new release of os-brick maybe that's causing issues? | 01:16 |
tommylikehu | mriedem: cinder will try to save the connection info in the new attach/detach APIs. we don't in the older style | 01:17 |
*** Apoorva has quit IRC | 01:18 | |
tommylikehu | mriedem: I thought you would save them in the nova side in the older attach/detach APIs. so I am wrong:) | 01:18 |
tommylikehu | s/in/at | 01:18 |
mriedem | nova saves the connection_info dict, returned by cinder, in the nova.block_device_mappings table as a serialized json blob | 01:20 |
mriedem | but it's assumed that the connection_info is a dict | 01:20 |
mriedem | and the host connector from os-brick is also a dict | 01:20 |
mriedem | what the values are within that dict, idk | 01:20 |
mriedem | does cinder's attachment_specs table assume all the key/values are strings? | 01:21 |
tommylikehu | mriedem: ok, now we save them in the key/value pairs such as metadata:) | 01:21 |
mriedem | yup http://git.openstack.org/cgit/openstack/cinder/tree/cinder/db/sqlalchemy/migrate_repo/versions/091_add_attachment_specs.py#n25 | 01:21 |
mriedem | it expects strings | 01:21 |
mriedem | idk why | 01:21 |
mriedem | the attachment_specs table probably doesn't even need to exist, it could have just been serialized json stored in the attachments table | 01:22 |
mriedem | it would have been faster that way anyway | 01:22 |
mriedem | so wwpns is a list and attachment_specs can't handle that | 01:22 |
mriedem | for fibrechannel | 01:22 |
mriedem | anyway, this is a cinder bug | 01:22 |
tommylikehu | mriedem: i have no idea, that's the problem, guess we don't have any trouble when trying iscsi | 01:22 |
mriedem | well i can see right here: "wwpns", ["21000024ff34c92d", "21000024ff34c92c"], | 01:23 |
mriedem | that's not going to work on a String column | 01:23 |
mriedem | unless you serialize it | 01:23 |
*** liverpooler has joined #openstack-cinder | 01:23 | |
mriedem | so, the fix on the cinder side is to probably always serialize the values before putting them into the attachment_specs table, and deserialize when you pull them out | 01:23 |
tommylikehu | yeah, if we serialize the connector, there is no need to separate them and store in the key/value | 01:23 |
mriedem | agree | 01:24 |
mriedem | but you've got this attachment_specs table right now | 01:24 |
tommylikehu | lol | 01:24 |
mriedem | there is no versioned object for attachment specs either | 01:24 |
mriedem | the connector is not returned back out of the API i don't think... | 01:25 |
mriedem | from the attachment_specs table | 01:25 |
mriedem | so idk what you'd want to do - either stop using attachment_specs altogether, and add a 'connector' column to the attachments table that is serialized json version of the connector dict you get from nova | 01:25 |
mriedem | that's what i'd do | 01:25 |
tommylikehu | mriedem: yeah, jgriffith will have the call | 01:26 |
mriedem | you could do an online data migration to migrate the existing data out of the attachment_specs table and into the new attachments.connector column | 01:26 |
mriedem | via the volume attachment object | 01:26 |
mriedem | migrate the data on read | 01:26 |
mriedem | use the new column on write | 01:26 |
tommylikehu | mriedem: will it looks like a little silly if we change the attachment_spec's text column from string to text :) | 01:28 |

openstack | Launchpad bug 1737724 in Cinder "FC attachment issue" [High,Triaged] | 01:30 |
mriedem | tommylikehu: string to text is not what i'm suggesting | 01:30 |
mriedem | i would stop using the attachment_specs table altogether | 01:31 |
mriedem | it's unnecessary | 01:31 |
mriedem | just store it in a text column in the attachments table as serialized json | 01:31 |
mriedem | nothing is ever going to index this data | 01:31 |
mriedem | i.e. you're not going to page volume attachments and filter on the connector blob :) | 01:31 |
mriedem | unless you're crazy | 01:32 |
mriedem | definitely a stop ship bug though for cinder | 01:32 |
tommylikehu | mriedem: yeah, it exists for several days, I noticed this bug, but everyone is waiting for jgriffith's feedback | 01:33 |

mnaser | jgriffith: smcginnis ill check the permissions and see if thats the reason | 21:29 |
smcginnis | mnaser: If that is it, we should probably get some better documentation added for that backend driver. | 21:30 |

mnaser | smcginnis: yeah, bummer is that the ceph user for cinder has access to the pool | 21:38 |
mnaser | so that means we're back to the drawing board | 21:38 |
smcginnis | mnaser: Shoot. Maybe jbernard or eharney will show up with some tips. | 21:39 |
mnaser | its doing a create almost every 2 seconds | 21:40 |
mnaser | i just wonder if it's blocking soemhow somewhere | 21:40 |
smcginnis | mnaser: Still not ideal, but you could at least make sure image_volume_cache_enabled is true. | 21:41 |
mnaser | smcginnis: if my brain parser of the code is operating, i dont think it uses image volume cache if it can clone it | 21:41 |
smcginnis | mnaser: It would still download the image unnecessarily, but at least it would just be once. | 21:41 |
smcginnis | mnaser: Hmm, maybe. It's been awhile for me since I've looked at that part. | 21:42 |

mnaser | Deadlock detected when running 'quota_reserve': Retrying... | 22:07 |
mriedem | https://github.com/openstack/nova/blob/stable/pike/nova/db/sqlalchemy/api.py#L3821 | 22:11 |
mriedem | yeah you'll probably want a retry decorator there | 22:11 |
mnaser | mriedem: its in cinder (and its retrying forever i guess) | 22:17 |
*** Apoorva has quit IRC | 22:17 | |
smcginnis | Hmm, we had a patch for something similar lately. Let me see if I can track that down. | 22:17 |
mnaser | https://github.com/openstack/cinder/blob/stable/pike/cinder/db/sqlalchemy/api.py#L1144 | 22:17 |
*** ChanServ has quit IRC | 22:17 | |
mriedem | mnaser: that's because it's using a super super super old version of that decorator from when cinder was nova-volume | 22:17 |
mriedem | :) | 22:17 |
mriedem | there is an oslo.db decorator for this | 22:17 |
mriedem | which limits the max number of retries | 22:17 |
mnaser | i figured just as much | 22:17 |
mnaser | i think they're just looping forever now | 22:18 |
mriedem | @oslo_db_api.wrap_db_retry(max_retries=5, retry_on_deadlock=True) | 22:18 |
mnaser | max_retries=5 is probably healthier | 22:18 |
mriedem | yeah there is no limit here https://github.com/openstack/cinder/blob/stable/pike/cinder/db/sqlalchemy/api.py#L244 | 22:18 |
mriedem | this seems like a task for a part time contributor | 22:18 |
mriedem | is that me?! | 22:18 |
mriedem | could it be possible for me to have 3 active cinder patches at one time | 22:19 |
mnaser | heh | 22:19 |
*** yangyapeng has joined #openstack-cinder | 22:19 | |
mriedem | mnaser: open a bug | 22:19 |
mriedem | please | 22:19 |
mnaser | mriedem: sure one sec | 22:19 |
smcginnis | mriedem: I can grab it if you want. But feel free to continue. :) | 22:20 |
smcginnis | mriedem: This is the newer retry decorator? oslo_db_api.wrap_db_retry(max_retries=5, retry_on_deadlock=True) | 22:21 |
mnaser | https://bugs.launchpad.net/cinder/+bug/1738292 | 22:21 |
openstack | Launchpad bug 1738292 in Cinder "Deadlocked queries retry forever" [Undecided,New] | 22:21 |
