Hi again! Today again met a strange behavior. I asked for a non-existent attribute of an existing node. # crm_attribute --type nodes --node-uname exist.node.domain.com --attr-name notexistattibute --query ; echo $? Could not map name=dev-cluster2-node2.unix.tensor.ru to a UUID 0 That is, to STDERR - swore, but the exit code - 0.
