This volume/pool has been working for months ok.
Now when migrating to other node will go comatose.
NW6.5sp3+ problem looks similar to TID10074467

One node loads the pool fine, it just won't migrate - so the script is ok.
Tried NSS /poolrebuild=poolname but it didn't help.
Interestingly enough, I couldn't run NSS /poolrebuild either from the
suspect node.
However, we have lots of pools that migrate ok.
Any ideas before Backup - blow away - recreate?
