ssh-copy-idはスクリプトループ（クラスタ）で異常に動作します。

私はあなたがなぜそれほど長い言葉を広げたのか理解できずsleep、私はあなたのプログラムの流れを正しく追跡したと信じていません。ただし、要件に応じて、以下が必要です。

gui* マシンはすべてにアクセスできる必要があり、Manager* マシンは管理者とワーカーにアクセスできる必要があり、ワーカーは他のワーカーにのみアクセスできる必要があります。

だから

• GUI→GUI管理者ワーカー
• 管理者→管理者ワーカー
• 労働者→労働者

それではそうします。あなたは自分の進捗状況の更新と終了ステータスを追加したいと確信していますが、この基本的な要素が役に立ちます。

#!/bin/bash
#
guis=(gui0)
managers=(manager0 manager1 manager2)
workers=(worker0 worker1 worker2)

# Grab the password
#
IFS= read -rsp "Master password: " sshpass && echo


# First, GUI to everything

    rm -f "$HOME/.ssh/id_rsa" "$HOME/.ssh/id_rsa.pub"
    ssh-keygen -t rsa -b 4096 -f "$HOME/.ssh/id_rsa" -P ""

for dst in "${guis[@]}" "${managers[@]}" "${workers[@]}"
do
    # Using the password we entered at the beginning, copy the keys everywhere
    SSHPASS=$sshpass sshpass -ev ssh-copy-id -o StrictHostKeyChecking=no -i "$HOME/.ssh/id_rsa" "$dst"
done


# Now generate a key on each host in turn
#

    # Ensure the target is clean and then generate a new key

done

do
    for dst in "${workers[@]}"
    do

    done
done


# Now fix up the "authenticity of host" warnings by connecting everywhere
#
for src in "${managers[@]}"
do
    for dst in "${managers[@]}" "${workers[@]}"
    do
        ssh -n "$src" ssh -n -o StrictHostKeyChecking=no "$dst" id >/dev/null
    done
done

for src in "${workers[@]}"
do
    for dst in "${workers[@]}"
    do
        ssh -n "$src" ssh -n -o StrictHostKeyChecking=no "$dst" id >/dev/null
    done
done


# Delete the unwanted key pairs from this host
#
for src in "${managers[@]}" "${workers[@]}"
do
    rm -f "$HOME/.ssh/id_rsa.$src" "$HOME/.ssh/id_rsa.$src.pub"
done


# All done
#

すべてはgui0クライアント（）によって制御され、このプロセス中に管理者またはワーカーは他のコンピュータにファイルのコピーを開始しません。

主な理由は、SSHがホスト（）を知らない~/.ssh/known_hostsため、ファイルに新しいホストを追加するように求められます。もちろん、スクリプトはこれに反応できません。

@roaimaが彼の答えに対するコメントで指摘したように、解決策は簡単です。 ssh ... -o StrictHostKeyChecking=no

私のスクリプトにはいくつかの他の問題があり、これを修正しました（コードを提供した@roaimaのおかげで、いくつかの点も改善しました）。

後でこれを行う必要がある人のために、私の作業スクリプトは次のようになります。
