I do have the expertise, but not sure about the time. It would be a reasonable undertaking. It would involve: 1) Updating the storage daemon to send the appropriate SCSI commands to inquire about error counts at mount and unmount times (or possibly with each block read / write.) This shouldn't be too bad as the sg_logs utility is out there and can access these statistics. The code could either be pulled from that tool, or the storage daemon could just call that tool and parse the results. 2) Updating the configuration syntax and parser for the storage daemon so the soft error recording logic could be enabled from the configuration file. 3) Changing the protocol between the storage daemon and the director to include the new soft error count information. 4) Changing the protocol between the director and the catalog service to include the new soft error count information. 5) Changing the schema in the configuration store to hold this new information. 6) Other stuff I haven't though of because I have only about an hour of looking at the bacula source code. My initial plan in my spare time is to mess around with the SCSI stuff in the storage engine and just send console messages back to the director. If I can get that to work I may play with the other stuff. I don't, however, take "playing with the other stuff" lightly. It involves protocol and database changes and I have no idea what the procedure and culture around here is for such things.
