Re: change strip_cache_size freeze the whole raid

Yes, I noticed this bug too, if you change it too many times or change it at the 'wrong' time, it hangs up when you echo numbr > /proc/stripe_cache_size.

Basically don't run it more than once and don't run it at the 'wrong' time and it works. Not sure where the bug lies, but yeah I've seen that on 3 different machines!

Can you tell us when the "right" time is or maybe what the "wrong" time is? Also, is this kernel specific? Does it (increasing stripe_cache_size) work with RAID6 too?

Thanks,

Steve
