Supersize io operations (IO block size more than 4KiB) is split in to number of 4KiB blocks
...is split in to number of 4KiB
blocks on Centos 7.3 ( where I don't see similar issue on 7.2). I have a
setup that involves TWO CentOS 7.3 servers. I tried to run 4MB IO on FC
LUN(s) on these servers discovered through Emulex LPe 16000 HBAs.
Changed ?options lpfc lpfc_sg_seg_cn =>1024? and ?max_secors_kb =>4MB?
params towards attaining supersize IO ( 4MB block size) , however there are
no improvements in getting more than 4K block size IO. There was no impact
from these changes.
Looking for a help to tune the system to attain supersize IO operation (4MB
writes)
