Hi Heinz (and list), I've got some interesting things for you to look at if you have time :) I've made a number of packages for processing events in dmraid. It's still in its initial stages, but I think it's a start for what we discussed all those many month's ago. There are four main pieces: The DSO A DSO registration utility A guide for setting up raid event monitoring using dmeventd (a start-to-finish kind of guide). And a Logwatch setup guide for processing the events that are stored into syslog (so a system admin can process the syslog to email alerts for example). The DSO will be registered with dmeventd and used to process device mapper raid 0, raid 1, and raid 4/5 events. At the moment the DSO just processes raid 1 since it's the only one generating events with Jonathan Brassow's patches (the 2.6.23 versions are attached here; I just got the 2.6.24-rc3 compatible ones yesterday). Right now I'm working on adding the eventing capability to the raid 0 kernel driver and then will work on it's section of the DSO. After that I'll tackle the raid4/5 portion of the DSO once your kernel patch is modified to work with the latest testing kernel. I wanted to find out your opinion as to where we would want to have this eventually live when it's finished? Do you think this would be a dmraid specific addition? For the DSO I would say that this is dmraid specific, but the DSO registration utility could be packaged with either userspace tool set (dmraid or dmsetup/dmeventd). I was thinking it might be useful for LVM users? I have built a "-m" command option that will dump a lot of useful information about all of dmeventds monitored devices (the number of events against a device, the actual identifiable underlying hardware devices like /dev/sda, /dev/sdb, etc...). For the next release I want to add giving a specific device name with the "-m" option to just dump a specific devices info (but that had to get pushed back since I had to get working on the kernel drivers and enhancing the DSO). I'm hoping this will be something users in the community like. At the moment I don't have a forward facing website to post these materials to and the mailing list won't accept this large of an email with the attachments. Heinz do you think once you give it a look we could post them on your Redhat page? If not I guess I could just email them to users that are interested.
