It's worth panicing if I > see a drbd write error on the secondary. Perhaps something like this. definetely not. IO means read _and_ write. both are not allowed. if you see this message, it is some application trying to access /dev/drbd while it is in secondary state. this message is never logged for drbd internal requests, those go to the lower level device, and if such io fails, depending on your config, a detach or panic will follow... you for sure will notice. -- : Lars Ellenberg Tel +43-1-8178292-0 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Schoenbrunner Str. 244, A-1120 Vienna/Europe http://www.linbit.com : __ please use the "List-Reply" function of your email client.
