Hi, During our Cinder upgrade on CentOS7 from Juno to Kilo, we ran into this bug: https://bugs.launchpad.net/cinder/+bug/1455726
As there is no fix available from what I see, what we came up with as a “solution” is to explicitly set the character and the collation in all existing tables in the database before the upgrade: —> alter database cinder CHARACTER SET utf8 COLLATE utf8_unicode_ci; SET foreign_key_checks = 0; ALTER TABLE `backups` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `cgsnapshots` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `consistencygroups` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `encryption` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `iscsi_targets` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `migrate_version` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `quality_of_service_specs` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `quota_classes` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `quota_usages` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `quotas` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `reservations` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `services` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `snapshot_metadata` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `snapshots` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `transfers` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `volume_admin_metadata` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `volume_glance_metadata` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `volume_metadata` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `volume_type_extra_specs` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `volume_types` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; ALTER TABLE `volumes` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; SET foreign_key_checks = 1; <— Note that in our case the databases default character set was already utf8 everywhere, while the collation was utf8_general_ci. With that conversion the upgrade seems to work fine in our tests. Before we retry the upgrade: do if people here think that this a reasonable approach or will this cause other issues? Are there alternative approaches? Thanks!
