https://bugzilla.kernel.org/show_bug.cgi?id=217965 --- Comment #41 from Eyal Lebedinsky (bugzilla@xxxxxxxxxxxxxx) --- OK, so how do I disable the stripe=640 that was automatically added? Is there a mount option to disable it? I would rather not futz with tune2fs. RE kernel build: I used to often do this maybe 30 years ago, but on a workstation, not on the server. The build I expect to be simple, but it is the risk of a bad patch that worries me. I would rather not do that. BTW, while you are looking at the cache issue, what are your thoughts on the fact that the array shows (iostat -x) a very high w_await when the members are much lower? Is it normal?
