Error on Delta Backup - cannot read property "length" of undefined
-
Hi folks,
is anybody facing this error? It just comes up on the lastest release - in the merge stage of Delta Backups - I'm seeing this error now on many XO implementations on our clients.
Regards, Claus

Hi,
What do you mean latest release? On XOA, if yes which release channel?
If you are using XO from the sources, double check here: https://xen-orchestra.com/docs/community.html
edit: what is the meaning of "many XO implementations on our clients"?

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
