Hi , i came across a problem with lvchange command.
I have a VG with 3 pv and a lv created using command
lvcreate -i3 -I32 -l98 -nmy_lv my_vg
lvdisplay shows 1024 as the value for Read Ahead Sectors.
When i use the command lvchange to change the value of read ahead
sector with value more that or equal to 256 i get following error..
linux# lvchange -r 340 /dev/my_vg/my_lv
lvchange -- ERROR "Invalid Argument" read ahead sector change
linux#
linux#
Is there a limitation that read ahead value cannot be greater
than 255?
Thanks
