> Software Raid != Hot Swap Actually I have figured out how to do a warm swap with out rebooting on a software SATA RAID.
Here's the steps: 1) mark drive in failure in RAID device 2) remove drive from scsi bus ie /proc/scsi/scsi 3) add new physical drive 4) partition drive 5) add new drive to /proc/scsi/scsi 6) add new drive to RAID device Depending on the controller steps 2 and 5 could be removed. Current SATA controllers from Intel, etc., do not provide enough information to allow this according to the SATA kernel maintainer. Step 4 can be removed by pre-partitioning the drive. I have one back up drive, and have partitioned it and read to go. I feel confident that I can recover from a failure. I think given time and better SATA controllers software RAIDs will approach the ease of use of hardware. Performance might be another issue. I believe that 3ware controllers are easier out of the box, but software RAID can provide a good level of reliability. In some ways I'm kind of glad the 3ware card didn't work with the supermicro. Gave me a good excuse to learn about SATA and software RAIDs. BTW, here a good source of info on the status of SATA in the kernel: http://www.kerneltraffic.org/kernel-traffic/topics/Serial_ATA.html -- Christopher Baus http://www.baus.net/ Tahoe, Wine, and Linux. _______________________________________________ RLUG mailing list [EMAIL PROTECTED] http://lists.rlug.org/mailman/listinfo/rlug
