#Today I learned about the write_mostly flag, which lets you mark a device in a #Linux software #RAID to be... well, mostly used for writes. In other words, the driver will prefer all other drives for reading operations.
Very handy in my current "#CMR drive together with #SMR drive" situation. I marked the slower SMR drive as write_mosty and so while this drive is busy doing all the writes, the other drive can perform all the reads and STILL have enough time to perform its own writes.
