    I already try to enable data-integrity check after the
verify/resync failed, but it didn't help. the verify/resync was not
correct and there are no "Digest mismatch" messages in kernel logs.

    I now will write a script to verfiy/resync the resource volumes
one by one, to see if all the resources volumes can be verify/synced

   or if you have other ideas need to try at the cluster please tell
me. the cluster is running many testing vms, so the corruption is
affordable for these vms.

   thanks a lot for your help!!
