When you rebuild a drive in a RAID array the size of the CMR region doesn't matter though, your array is either going to explode due to the latency spikes that come or take weeks to rebuild.
- rbanffy 6y agoIsn't it possible to query the drive and, if it is SMR, just send the data to the disk in the order it expects so that it can resilver the drive one SMR region at a time? This seems more like a misunderstanding between the drive and the OS in that the drive doesn't tell the OS it'll need a break between write batches and an OS that tries to write to the disk in a way that's not compatible with the device technology. The same more or less applies to SSDs - the drive can't write a disk block, but only a memory block at once.
