After default instalation, after zpool create zfs1 raidz2 /dev/disk/sd{b,c,d,e,f,h}
I have:
root@vps1:/sys/block/sda/queue# cat /sys/block/sd{b,c,d,e,f,h}/queue/physical_block_size
4096

and:
root@vps1:/sys/block/sda/queue# cat /sys/block/sd{b,c,d,e,f,h}/queue/logical_block_size
512

1. Is it worth to change the logical size? (performance difference)
2. How to change the logical size without/low downtime?
Regards.
