Replication is leaving VDIs attached to Control Domain, again
-
Using updated XCP 8.3 and XO (current master 21767) Continuous Replication is sometimes (1%) leaving VDIs attached to Control Domain.... again. The backups and tasks do finish correctly.
I don't know exactly when it started happening (may be around 8448b4d the 6.0 release, but not exactly that version) and it's not something that happens all the time. Sometimes once a day, other days several times.
This problem was happening a long time again and then it was fixed in XO (a year ago) and everything was good. This may be a timing issue again that XO is just not finishing removing the attached VDI for backup (need longer waiting and retries?)
I know it's not a lot of info. This is more of a "be on notice" that something is happening, maybe others have the same issue again.

@Andrew is it always the same VM/disk ?

@florent Different random ones.

@florent With CR running and NBD enabled for 2, I see both exports and one import (per disk). It's never the import that's stuck and only one (not both) of the exports (if it happens).
I have updated XCP 8.3 to the new January 2026 patch and XO to current master and will keep an eye on it again.
