[linux-lvm] volume developing problems even though should be static...

I needed extra space on my home partition, and speed, so I disabled my
snapshoting cron job and deleted any logical jobs for now.
But during this transition time, I've started getting some were symptoms.
Now when I do a "pvs", I see:
# pvs
/dev/dm-1: read failed after 0 of 4096 at 0: Input/output error
PV VG Fmt Attr PSize PFree
/dev/sdb1 Home lvm2 a- 888.48G 0
/dev/sdb2 Home lvm2 a- 888.48G 640.96G
/dev/sdb3 Home lvm2 a- 584.87G 584.87G
# vgs
/dev/dm-1: read failed after 0 of 4096 at 0: Input/output error
VG #PV #LV #SN Attr VSize VFree
Home 3 7 6 wz--n- 2.31T 1.20T
# lvs
/dev/dm-1: read failed after 0 of 4096 at 0: Input/output error
lvol0 Home -wi-ao 1.00T
-----------------------------------------------
So, the "output of the commands looks mostly 'right', as near as I can tell: 3 physical volumes,
-> 1 volume group with the 3 volumes, and
1 logical volume taking up space in that pv (only using part of the space).
What I don't get and what worries me a fair amount are the I/O errors --
any idea what's going on and how I shoudl fix this?
Thanks much!
