Vincent, Problem reproduced. Steps to reproduce: 1. drbdadm down <resource> 2. remove underlying device (e.g. rename logical volume) 3. drbdadm up <resource> after "drbdadm up", DRBD issues this error message: Can not open device '<local device>': No such file or directory Command 'drbdsetup /dev/drbd<num> disk <local device> <local device> internal --set-defaults --create-device --on-io-error=detach' terminated with exit code 20 This is likely to confuse users. This doesn't mean that the "up" command failed altogether. "up" is really the combination of "detach" and "connect"; "detach" fails here while "connect" proceeds as normal. The device is then Diskless. But, the in-memory representation of the sync bitmap was never initialized. 4. drbdadm primary <resource> 5. issue any write I/O to DRBD device. When write I/O is issued after the device has been made Primary, DRBD attempts to update an in-memory sync bitmap that isn't there. Hence your error messages in the kernel log. This is a bug. A fix is being worked on. It is not fixed in 8.0.8. Still, you would never have run into this issue if your underlying disks hadn't been totally broken (as they were, apparently). From your last message, it appears that you have fixed your setup, and also ran a full resync to be on the safe side. Which is a good thing. Cheers, Florian -- : Florian G.
