Some linux tools are available on a CD included with the controller. If such information is easily available, monitoring tools can be written to detect and report failures. As I said, my bus is bigger than the all disks combined 2 Hotswap. I have a bunch of benchmark statistics for my array, but it’s more a filesystem benchmark than a RAID benchmark. Which is nice because I really like to use LVM. Im currently about to play around with this some, any suggestions?

The array-info tool can extract the RAID status for cciss devices. I have a bunch of benchmark statistics for my array, but it’s more a filesystem benchmark than a RAID benchmark. Driver name Name of the Linux kernel module.

I’ve contacted 3ware support and explained my awful performance issues and all lnux testing I’ve done. Software RAID lets me easily move disks to other controllers or even to other machines. Just create one partition that’s slightly smaller than the actual drive size, e. Have something to say? Also, afacli requires libraries that are no longer available in Debian distributions. Can you switch between those other two storsave profiles?

The card specs says it’s Mhz but can also run at Mhz or 66 Mhz. What can be the cause of all this? How serious can the data loss be?

But with regular hardware not the expensive server stuff it can be hard finding the exact model drive again. Like some bad sectors? The interface may linuxx responding a few seconds. Also for read look at blockdev –help. I will write more about this later. Supported Supported by Linux kernel?


If you got redundant power supplies, don’t worry too much. I would’ve already contacted the manufacturer or reseller and requested my money back, or an exchange for a different unit.

I hope to have it finished this week. It also handles failure detection and report it by mail and syslog.
