i have found that on raid 1, chunk size does not matter for performance. what matters more seems to be the block size option to mke2fs. i make my mysql stores with chunksize 16, and run mke2fs with -R stride=4 -b 4096 allan Erich <[EMAIL PROTECTED]> said: > > I looked through the documentation

Ok, here are the notes that I wrote to myself of how to get Software RAID and the Promise Ultra/66 in the same kernel: 1. Don't use the RedHat version of the 2.2.14 kernel. It has too many patches, so the other patches won't work. 2. Do unpack the linux-2.2.14.tar.gz file. 3. Apply the ide.2.
