Hi, One of the drives in my raid1 recently crashed and it looks like all the replacement disks (2TB) i can find use 4K sectors, but the old ones were 512 bytes. Are there any issues with having a raid1 array with different sector sizes for the drives? Regards, Henrik
I can't answer for sure, but I would think there would be no problem as long as you make sure your partitions are 4 KB aligned. AFAIUI, Linux always writes in 4K blocks to the disks anyway, so alignment is the only issue - and that's a performance issue, not a correctness one.
