@Tristis-Oris hi tristis , can you show us the full stack trace got the error on rename ?

can you make a healthcheck on the suspicious backups and see if it can restore ?

@Tristis-Oris hi,I see two problem :

an older merge failed for all theses VM , and some block ae missing ( 2/49 for the fisrt one, 2/52 for the second one) . These backup are irrecuperable and should be deleted
there is a desynchro between the cached metadata and the file system, you can delete them by running
find /mnt/mih-5300-2/xo-vm-backups/ -name "cache.json.gz" -type f -delete

@florent i understand that this backup maybe corrupted. But if some VMs failed first time only yesterday, that mean something continues to corrupt this procedure.

Also some VMs with that error sometimes do backup without errors.

And i already tried to remove the whole backup chain or do backup with another task - to force full backup creation. But anyway got this error.

restored one this backups - VM run and work fine.

@Tristis-Oris have you got a XOA which we could use to access your system ?

Tristis Oris

@florent sure, i'm deployed XOA already.
what you need to get access?

@florent said in Backup timeout - hang or didn't work:

find /mnt/mih-5300-2/xo-vm-backups/ -name "cache.json.gz" -type f -delete

That works, removed them finally. Thanks.

@Tristis-Oris can you open a support tunnel and give me the access code ( by direct message ) ?

I would like to look into this in detail since we made quite a lot of changes on the merge and the caching recently
regards

Tristis Oris

any progress with that problem?

STeffaine

any updates? im also having this issue.

Tristis Oris

After bunch of last fixes i removed some broken backup chains and now all errors gone. Thanks.

@olivierlambert to not create new topic, small continue here.

timeout option still ignored.

probably because of network problems i got backup error and job hangs every day.
doesn't matter why it happens, but job will never get terminated by timeout.

21h job with 7h timeout. https://pastebin.com/U5HgKEzM
just 1 Gb.

i setup scheduled task to reboot xo once a day, to close this endless tasks.
