Re: Faster read performance DURING (?) resync on raid10

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I'm using near=2, far=1, superblock version=00.90.03

I'm not sure about offset, but its the default.

I wan't to clearify one thing about the data, its not only a problem
with encryption over raid, you get the same drop without encryption...
but you can remedy it by setting up the readahead, which gives no
effect when using encryption.
