Re: [linux-lvm] System Suggestions
We have 10 of the 3ware cards, and while the drive is GPLd and in the kernel, we have not been satisfied with the stability of the system Is there anything that I can avoid while still using the card (ie; specific RAID config)? We haven't had a chance yet to qual the latest firmware, etc., but we went with dumb IDE expansion cards (we're only using 4 ide drives per system) and we're getting better speed (RAID0 or 1+0 depending) than we were off the 3ware card. We are not using XFS, so no comments there. We're also having some problems with Mysql that people keep pointing fingers at LVM for, but at this time we're point right back and saying No! in a firm voice... What kind of problems with MySQL, if you don't mind to summarize?

re[2]: [linux-lvm] System Suggestions
Anthony, I'd be careful with the IDE Raid controller. We just built a lab machine with a Promise IDE Raid controller and the assumption that we could get it and XFS to co-exist. I'm not doing the work, but the engineer that is tells me that the Promise Patch Kit only works with a very limited number of stock Redhat Kernels, and that we are NOT free to add the XFS patch. Even worse, promise does not supply their patch in source, so we are not free to tweak it ourselves. I'm not sure I really believe that, but that is what I'm told. If you do get the 3Ware IDE RAID controller to work with XFS, please let me know.

Works beautifully. Have RH7.2, XFS, LVM, and a 3Ware 7410 running the box that I'm sending this from. :) The Promise RAID cards are cute but crappy from what I've heard. The 3ware cards seem to be excellent quality so far, and the driver (as far as I can tell) was GPLed and is standard in the 2.4 kernel series (well, it's in 2.4.9 anyway...)

So you're doing software RAID now? Some more specifics would be appreciated. What 3ware cards? 7410s? What type of drives? What motherboard? Were you doing RAID 1+0? Do you run your application-specific benchmarks, or general benchmarks? Have any actual numbers?
