OwnCloud 8.2.9 to NextCloud 9.0.55 migration - oc_mounts doesn't exist

[tekkk]

Hello,

first of all greeting to all members of the Nextcloud community. I have been searching for answers in Google and on the OwnCloud + Nextcloud forums. Yet I have not been able to find any answers.

The problem is very weird, especially since it happens on the 2 instances of OwnCloud. I was trying to update form OC 8.2.9 to Nextcloud 9.0.55 and right at the beginning of ugrade process I receive information “An error has occured”.

Log file entry:
{"reqId":"DI2r2bzwJA7setRxACVg","remoteAddr":"*.*.*.253","app":"index","message":"Exception: {\"Exception\":\"Doctrine\\\\DBAL\\\\Exception\\\\TableNotFoundException\",\"Message\":\"An exception occurred while executing 'SELECTstorage_id,root_id,user_id,mount_pointFROMoc_mountsWHEREuser_id= ?' with params [\\\"email@email.com\\\"]:\\n\\nSQLSTATE[42S02]: Base table or view not found: 1146 Table '00059792_0000019.oc_mounts' doesn't exist\",\"Code\":0,\"Trace\":\"#0 \\\/cloud\\\/3rdparty\\\/doctrine\\\/dbal\\\/lib\\\/Doctrine\\\/DBAL\\\/DBALException.php(116): Doctrine\\\\DBAL\\\\Driver\\\\AbstractMySQLDriver->convertException('An exception oc...', Object(Doctrine\\\\DBAL\\\\Driver\\\\PDOException))\\n#1 \\\/cloud\\\/3rdparty\\\/doctrine\\\/dbal\\\/lib\\\/Doctrine\\\/DBAL\\\/Connection.php(836): Doctrine\\\\DBAL\\\\DBALException::driverExceptionDuringQuery(Object(Doctrine\\\\DBAL\\\\Driver\\\\PDOMySql\\\\Driver), Object(Doctrine\\\\DBAL\\\\Driver\\\\PDOException), 'SELECTstorage…’, Array)\n#2 \/cloud\/lib\/private\/db\/connection.php(184): Doctrine\\DBAL\\Connection->executeQuery(‘SELECT storage...', Array, Array, NULL)\\n#3 \\\/cloud\\\/3rdparty\\\/doctrine\\\/dbal\\\/lib\\\/Doctrine\\\/DBAL\\\/Query\\\/QueryBuilder.php(206): OC\\\\DB\\\\Connection->executeQuery('SELECTstorage…’, Array, Array)\n#4 \/cloud\/lib\/private\/db\/querybuilder\/querybuilder.php(141): Doctrine\\DBAL\\Query\\QueryBuilder->execute()\n#5 \/cloud\/lib\/private\/files\/config\/usermountcache.php(188): OC\\DB\\QueryBuilder\\QueryBuilder->execute()\n#6 \/cloud\/lib\/private\/files\/config\/usermountcache.php(110): OC\\Files\\Config\\UserMountCache->getMountsForUser(Object(OC\\User\\User))\n#7 \/cloud\/lib\/private\/files\/config\/mountprovidercollection.php(97): OC\\Files\\Config\\UserMountCache->registerMounts(Object(OC\\User\\User), Array)\n#8 \/cloud\/lib\/private\/files\/filesystem.php(435): OC\\Files\\Config\\MountProviderCollection->registerMounts(Object(OC\\User\\User), Array)\n#9 \/cloud\/lib\/private\/files\/filesystem.php(353): OC\\Files\\Filesystem::initMountPoints(‘email@email…’)\n#10 \/cloud\/lib\/private\/util.php(223): OC\\Files\\Filesystem::init(‘email@email…’, ‘\/email@email…’)\n#11 \/cloud\/lib\/base.php(906): OC_Util::setupFS()\n#12 \/cloud\/index.php(47): OC::handleRequest()\n#13 {main}",“File”:"\/cloud\/3rdparty\/doctrine\/dbal\/lib\/Doctrine\/DBAL\/Driver\/AbstractMySQLDriver.php",“Line”:53}",“level”:3,“time”:“2017-01-01T12:26:39+01:00”,“method”:“GET”,“url”:"/cloud/index.php/core/js/oc.js?v=b540ba4c098dd20fb128f34880d30f8d",“user”:“email@email.com”}`

And indeed on BOTH instances table oc_mounts is missing form database structure.
I also tried upgrading do OwnCloud 9.0.7 but with exactly same effect.

Any ideas? Thank you in advance!

How did you upgrade? Seems a bit similar to this topic, oc_mounts seems to be a new table in version 9 as well:

Issue: Internal Server Error when logged in after Upgrade 8.2.2 to 9.0

Have you tried just manually adding the new table into MySQL, either through the MySQL commandline or something like PHP? If there’s no data missing, just the need for a table to put them in, this might solve your problem…

Thank you for your support. Following Bugsbane advice I have:

• prepared fresh instalation of Nextcloud 9.0.55
• exported structure of the oc_mounts table from fresh instalation
• imported it to OwnCloud 8.2.9. existing database - in order to add missing oc_mounts table to database
• changed OC 8.2.9 folder (\cloud) name to (\cloud-bak)
• uploaded Nextcloud 9.0.55 to FTP to \cloud folder
• moved config.php and \data folder
• via web browser I went to http:\domain\cloud
• Nextcloud offered an upgrade
• upgrade again resulted in notice: “An Error has occured”
• however this time log showed something different:

I am clueless right now… any suggestions?

BUMP! Is there any chance that this migration issue will be solved?
Thank you in advance for any hints on the problem!
