well that's the thing I read in other post that those are since the multipath is not started during bootup
but I just got home and I found these
kernel: printk: 20 messages suppressed.
kernel: Buffer I/O error on device sdc, logical block 0
kernel: Buffer I/O error on device sdc, logical block 0
kernel: Buffer I/O error on device sdc, logical block 14417919
kernel: Buffer I/O error on device sdc, logical block 0
kernel: Buffer I/O error on device sdd, logical block 0
kernel: Buffer I/O error on device sdd, logical block 0
kernel: Buffer I/O error on device sdd, logical block 14417919
kernel: Buffer I/O error on device sdd, logical block 0
kernel: Buffer I/O error on device sdf, logical block 0
and I left this system 4 hours ago and still getting these messages well those above are the only ones
I get the point during boot up even when the boot up process is slow because of those messages I don't know why while the server is up and running

is there a way to avoid multipath be sensing the passive paths?
