[DRBD-user] Does the error "Buffer I/O error on device" mean I damaged something?

Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


I didn't think executing vgdisplay on the underlying volume group 
would trip up drbd devices above in secondary state, but apparently 
it does:

Jun 25 12:42:10 [kernel] [37534.990852] Buffer I/O error on device 
drbd0, logical block 3581840
Jun 25 12:42:19 [kernel] [37543.505905] drbd1: Not in Primary state, 
no IO requests allowed

Does it actually mean there could be damage, or it is just trying to 
frighten me into never executing any command whatsoever other 
drbd-specific ones on my device?
