ApacheでSSLの設定をしたのですが、特に複雑な設定もなかったので一発でいけるだろうと思って、ドヤァ!ってブラウザたたいたら、表題のエラーメッセージ。

で、設定を見直すと、、、mod_ssl.soをLoadModuleしてなかった...しにたい...

"/etc/samba/smb.conf" の [global] セクションに以下2行を追記。

wide links = yes
unix extensions = no

(セキュリティ上、新しいバージョンでは、デフォルトでシンボリックリンクを扱えない)

DRBDでセカンダリを切り離したりとか

改めてメモ。

heartbeat等、使ってる場合は、そちらも止めてから。

primary# drbdadm role r0
Primary/Secondary

secondary# drbdadm role r0
Secondary/Primary

secondary# drbdadm down r0

primary# drbdadm role r0
Primary/Unknown

secondary# drbdadm up r0

primary# drbdadm role r0
Primary/Secondary

ちなみに"up"はattachとconnectの両方を実行してくれる。

"down"はその反対で、disconectとdetachの両方を実行してくれる。

OSインストール時のブートパラメータに"resolution"で指定する。

> vmlinuz initrd=initrd.img nomodeset resolution=1024x768

こんな感じで。
