One further question. I get these messages 'in' dmesg :
sda: asking for cache data failed
sda: assuming drive cache: write through
How can I force it to be 'write back'?
Forcing write back is a very bad idea unless you have a battery backed
up RAID controller.
We do.
In any case, I wonder what the consequences of assuming 'write through'
when the array is configured as 'write back'? Is it just different
settings for different caches?
