Continuos replication failing with "checkBaseVdis() failed"
-
Hello forum,
Anyone else getting this warning / error on contionuos replication?
I think this is related to using "Distribute replication accross the storage repositories" option
This is happening on my daily replications using 4 storage repositories on the destination pool. The replicated VM snapshot doesn't get updated (at least the timestamp on the description doesn't). I also think that the replication is failing because the log does not show any data transfer to the storage repositories on the destination pool.
In case it has something to do with this: On the same job I'm also doing delta backups. Other options are NBD, CBT and merge backups sinchronously. Replication retention is set to 1 on the job schedule, which is called from a job sequence. Storage repositories are lvmoiscsi.
Thank you,

@pedro_udifar What is your current commit for the XO VM? Can you share the full error log as an attachment?

@Danp Hi!
Running Xen Orchestra, commit 44e5b (19 commits behind).
Here is a log
deltalog.txtThank you!

@pedro_udifar Please update to the latest code base and then let us know if you still encounter this issue.

Hi @Danp ,
I've updated XO to the latest commit and the error is still happening.

Hello,
More info on this. I think this error is related with the recent "Distribute replication accross the storage repositories" option that I turned on. Before this option existed, I was splitting the VMs into groups, with tags, and using several jobs with "smart mode" to send each group to a specific SR on the destination replication pool. With this new option I didn't have to do this anymore, it would simplify my replication job.
That said, I still have a group that I want to replicate to a local host disk. This group doesn't fail with "checkBaseVdis() failed" but I do get duplicated VMs on the destination pool, even though the job's schedule is set to only 1 replications retention. Is XO failing to delete the previous VM replication ?
(The same VM duplicated on the replicated pool even though replication retention is set to 1)
(Job / schedule retention settings)....So I have to prune the duplicated VMs to make sure I don't run out of space on the target pool repository.
I think I'll set up a new job with a single test VM so I can run it several times and try to gather more info.

Hello!
So I created a new job and a small test vm to gather info. I did 3 replications runs and the last 2 failed. Backups are working thoug.
Since this would be a large post, I created a pdf with the test cycle.
...
Only to find out that those are not allowed on this forum! So I captured the pdf pages...
And the logs from the jobs:
