Error on Delta Backup - cannot read property "length" of undefined
-
I had the same problem in my homelab - xo from sources, installed it the official way from the documentation. updated via
git pull --ff-only3 days ago. the backups are failing with the error message:"tasks": [ { "data": { "type": "VM", "id": "abc2c07e-33e8-97e2-6724-3e69f837d0f7" }, "id": "1617691268721:0", "message": "backup VM", "start": 1617691268721, "status": "failure", "tasks": [ { "id": "1617691271853", "message": "snapshot", "start": 1617691271853, "status": "success", "end": 1617691328127, "result": "74c58079-3e89-53db-a770-6f3b936833b2" }, { "id": "1617691328128", "message": "merge", "start": 1617691328128, "status": "failure", "end": 1617691328128, "result": { "message": "Cannot read property 'length' of undefined", "name": "TypeError", "stack": "TypeError: Cannot read property 'length' of undefined\n at /home/toor/xen-orchestra/@xen-orchestra/backups/_DeltaBackupWriter.js:114:31\n at Zone.run (/home/toor/xen-orchestra/node_modules/node-zone/index.js:80:23)\n at /home/toor/xen-orchestra/node_modules/node-zone/index.js:89:19\n at Function.fromFunction (/home/toor/xen-orchestra/@xen-orchestra/backups/_syncThenable.js:20:27)\n at SyncThenable.fulfilledThen [as then] (/home/toor/xen-orchestra/@xen-orchestra/backups/_syncThenable.js:2:50)\n at TaskLogger.run (/home/toor/xen-orchestra/@xen-orchestra/backups/Task.js:77:10)\n at Object.run (/home/toor/xen-orchestra/@xen-orchestra/backups/Task.js:157:17)\n at DeltaBackupWriter._deleteOldEntries (/home/toor/xen-orchestra/@xen-orchestra/backups/_DeltaBackupWriter.js:108:17)\n at Array.<anonymous> (/home/toor/xen-orchestra/@xen-orchestra/backups/_VmBackup.js:150:70)\n at Function.from (<anonymous>)" } } ], "end": 1617691344109, "result": { "message": "Cannot read property 'length' of undefined", "name": "TypeError", "stack": "TypeError: Cannot read property 'length' of undefined\n at /home/toor/xen-orchestra/@xen-orchestra/backups/_DeltaBackupWriter.js:114:31\n at Zone.run (/home/toor/xen-orchestra/node_modules/node-zone/index.js:80:23)\n at /home/toor/xen-orchestra/node_modules/node-zone/index.js:89:19\n at Function.fromFunction (/home/toor/xen-orchestra/@xen-orchestra/backups/_syncThenable.js:20:27)\n at SyncThenable.fulfilledThen [as then] (/home/toor/xen-orchestra/@xen-orchestra/backups/_syncThenable.js:2:50)\n at TaskLogger.run (/home/toor/xen-orchestra/@xen-orchestra/backups/Task.js:77:10)\n at Object.run (/home/toor/xen-orchestra/@xen-orchestra/backups/Task.js:157:17)\n at DeltaBackupWriter._deleteOldEntries (/home/toor/xen-orchestra/@xen-orchestra/backups/_DeltaBackupWriter.js:108:17)\n at Array.<anonymous> (/home/toor/xen-orchestra/@xen-orchestra/backups/_VmBackup.js:150:70)\n at Function.from (<anonymous>)" } },I created a new delta backup job and it works now, deleted the old one - but its not the best solution, maybe something is incompatible with the last releases in the master branch to old backup jobs?
hope to help other people with a quick workaround, but hopefully the xoa guys can look into that - great job btw!
cheers, Ringo
-
Maybe a transient issue on
master. That's why, when there's an issue, it's important to check you are on latestmastercommit and try again
-
@olivierlambert yes I thought the same so I updated the code from the master again yesterday but didn't help
-
Have you tried to create a new job since the update?
-
I can confirm having the same issue on two XO instances since upgrading to 5.78.2 / 5.80.0
-
Only
mastermakes sense There's no "release" concept on the sources. Please update to latest mastercommit, recreate a job and report if you still have the problem

@olivierlambert Hi Olivier,
I updated both instances, recreated the jobs and while backups on one instance now work again, on the other they still fail:{ "data": { "mode": "delta", "reportWhen": "failure" }, "id":

Does it ring any bell @julien-f ?
-
Nope, I don't see how this error can occur, are you up to date with
master? -
At least I think so. I worked with svn for years but that was ages ago and I never got into using git.

@mbt A simple
git pull --ff-onlyshould do the trick.Anyway, I think I found the issue
-
Should be fixed on
master, please test and keep me postedFYI https://github.com/vatesfr/xen-orchestra/commit/8e4c90129e2ce82cd1d4097005048c0564898e72
