This is how the pool looked like,

|# zpool list vmpool NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP
HEALTH ALTROOT vmpool 372G 257G 115G - - 64% 69% 1.00x ONLINE - |

Scrub did not show the errors. After deleting unused zvols, the guests
started to work and pool looks like this,
|
|

|# zpool list vmpool
NAME     SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP 
HEALTH  ALTROOT
vmpool   372G   197G   175G        -         -    56%    53%  1.00x
