Hello.
My boss wants me to add disk errors uevents, to get information on faulty devices. He told me catching dmesg information using syslog is not reliable and he would like to get 100% certain information. I know there are currently implemented uevents in the device mapper layer, but they are limited to multipath targets. Even if error events were added to the device mapper, would it be impossible to find out which physical device generates errors if the device mapper works on top of the software RAID (correct?).
Does it make sense to add such a functionality to the block layer (or somewhere else), and also could such a modification be included in the mainline kernel, or should I rather convince my boss to implement it via syslog?
