When I run the lvdisplay, it showed the following error...
/usr/sbin/lvdisplay
/dev/sdb: read failed after 0 of 2048 at 0: Input/output error
/dev/sdb1: read failed after 0 of 2048 at 0: Input/output error
/dev/sdb2: read failed after 0 of 2048 at 0: Input/output error
/dev/sdb3: read failed after 0 of 2048 at 0: Input/output error
--- Logical volume ---
...
I can still see my volumes, when the error is showing everytime, any idea?
