Hallo Aleksandr, Thanks for the report. We are looking into this issue and have an idea of what may be causing it.
The issue appears to be related to Kubernetes. In particular, to some unusual actions taken by the CSI driver. There is a workaround available in the CSI driver that avoids these unusual actions. See: https://github.com/piraeusdatastore/piraeus/issues/178#issuecomment-2027051506 We will post an update when we make progress in fixing the DRBD bug. Best regards, Joel
