Since there is a bit more steam on the system, I get irregular but predictable SSH connection disconnects (ssh client loop send disconnect: Broken pipe). I have already tried all possible combinations of ClientAliveInterval and ServerAlivceInterval (and -CountMax), also TCPKeepAlive. Nothing has changed this situation. Even if I run the Ssh server in the DomUs with -d -d -d (debug level 3), I see no evidence of a cause around the time of the abort.A `Broken pipe' from ssh means the RHS of the pipeline exited prematurely. Does dd report anything? media errors? filesystem full? O_DIRECT constraint violations (offsets and sizes not aligned to block-size because dd(1) is reading from a (network) pipe--though this is not a problem on UFS)?
thanks for your response and pointing me to the dd... I did not think about this could contribute to the issue at first but it sounds like something important to consider. Basically I use dd to get at least some kind of return code on the host e.g. if the target media is full or not writable for some reason.
Before I had dd in place, I used a redirection > $dumpname which results in the same kind of broken pipe issues. I just did verify this by repeating this as an isolated test case.
Kind regards Matthias
