Has anyone had any experience or comment regarding linux RAID over ieee1394?
I've been successfully running a 4x250Gb Raid5 over ieee1394 with XFS on top. The 4 drives are sharing the same ieee1394 bus, so the bandwidth is awfull, because they have to share 20Mb/s. It happens from time to time that one drive is temporary lost, so I must re-add it and resync... (I would have liked to put a bitmap on it, but I get an oops... I did not have time to give it a closer look yet).
As a budget backup solution, I am considering using a pair of 500GB drives, each connected to a firewire 400 port, configured as a linear array, to which the contents of an onboard array will be rsynced weekly.
I would really suggest you to study a 3-drive raid5 scenario, because the risk of temporary loosing a disk is not neglectible... Regarding to the cost of an extra disk. That was my 2cents.. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
