Hi. I'm interested in setting up a system which can monitor the status of an aacraid-based RAID system, ideally via dbus. I've seen solutions on the web that poll the system using the 'afacli' command line tool, and parse the output. This seems less than optimal. I want a system which doesn't use polling. Surely it's possible to have the kernel send out notifications if the health status of the RAID changes? Ideally these would be available via HAL (hald) and sent to user space via dbus. I'm willing to patch the kernel and hald if required. If no such solution exists, I may be able to spend some paid work time writing it. If I did, would there be some chance of getting it into the official driver? Would other people find this useful? I've been grepping the sources of .../drivers/scsi/... looking for examples of kernel events or hotplug being used to notify user space of changes in the RAID array health, without any luck. Does any other driver, (or the software RAID system) do anything like this? Thanks in advance for any tips or pointers. Please reply directly, as I'm not currently subscribed to linux-scsi. If I get multiple off-list messages, I'll write and post a summary.
