Is that possible without reinstalling? it seems to me that you are still not understanding what is happening here. i get the impression that you want to write these backup scripts to avoid data loss in the event of a disk failure? you are right about the computer having two physical disks. however, these are plugged into a raid controller, which is configured to mirror the two physical disks. the operating system (openbsd) only sees this mirror, not the actual disks. if one of the physical disks fails, the raid controller will continue to happily use the other disk. you wont lose data, and you wont lose uptime either since the system is still running. to recover from the disk failure simply swap the bad disk out and the controller should mirror from the good disk to the new disk and regain its redundancy. if you're only trying to avoid data loss when a disk fails, then stop writing your backups scripts and start writing a cronjob that mails you when bioctl reports one of your disks as failed. dlg

I'm only trying to create a archive of backups. So it would backup the sytem every day and every week it would save one of the backups to another directory while continuing to overwrite the other weekly backups and doing the same with a monthly backup while overwriting the weekly backups. So I would have 7 daily backups, 52 weekly backups and 12 yearly backups when the system is full. if you're only trying to avoid data loss when a disk fails, then stop writing your backups scripts and start writing a cronjob that mails you when bioctl reports one of your disks as failed. Do I have to parse sudo bioctl ami0 or is there a way to run bioctl and get an true/false value for the alarm status? I tried sudo bioctl ami0 -a get ami0 but that returns a value reporting wether or not the alarm is enabled. Thanks! http://messenger.msn.click-url.com/go/onm00200471ave/direct/01/
Re: I can't find my scsi hard drives...
If you want backups get a tape drive. Do not rely on disk for backups, especially if they are in the same machine. If you don't know how to do this I advice you to get some consulting. You are asking very basic administration questions and these lists are not the appropriate forum for that.

You are asking very basic administration questions and these lists are not the appropriate forum for that. I don't have the money for a tape drive. They are expensive. And most people are not writing bioctl so these questions are not very basic. Thanks for your help before but give me a break here, I'm reading the man pages, I'm trying. Basicially you are saying if you don't know the answer then it might be a good question. Fuck that. http://messenger.msn.click-url.com/go/onm00200471ave/direct/01/
