Rubens, Do you mean you recovered it ? What have you do to get it working again ?

I guess it is possible to reproduce the error, and then capture the output from collie cluster info. Anyway, the upcoming "collie cluster check" command is a very good news.

Is sheepdog protected against > such kind of failure, in which all nodes are abruptly disconnected? Sheepdog should handle the total node failure, but I think some bugs still exist in it. The error handling has not been tested enough. If you have not cleaned the damaged cluster yet, can you give me the outputs of "collie cluster info" on all the nodes? Those info would be helpful to find the error reason. I'm implementing a "collie cluster check" command, which works like fsck for Sheepdog. This command would be helpful for recovering the damaged cluster. Thanks, Kazutaka
