Hi. I'm playing around with (software) raid0 on SSDs and since I remember I read somewhere that intel recommends 128K stripe size for HDD arrays but only 16K stripe size for SSD arrays, I wanted to see how a small(er) stripe size would work on my system. Obviously with btrfs on top of md-raid I could use the stripe size I want. But if I'm not mistaken the stripe size with the native raid0 in btrfs is fixed to 64K in BTRFS_STRIPE_LEN (volumes.h). So I was wondering if it would be reasonably safe to just change that to 16K (and duck and wait for the explosion ;) ).
Can anyone adept to the inner workings of btrfs raid0 code confirm if that would be the right way to proceed? (obviously without absolutely any blame to be placed on anyone other than myself if things should go badly :) ) Thanks john -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
