How to continue failed playbook on several hosts ?

Hello all,

some time ago I wanted to run quite lengthy playbook on several (over 100 …) nodes. These nodes are not really similar so I wasn’t surprised that on many of them
this particular playbook failed (to make it worst: it failed on different tasks …). So at the end I was left with several servers with partially run playbook.

tasks on these particular nodes” ?

Best regards
