sambaのDNSでは委任(delegate)ができないようだ

このエントリーをはてなブックマークに追加

PowerScaleシミュレータのSmartConnect動作を見てみようと、samba 4.15.5で作ったActive DirectoryのDNSサーバ機能で名前解決動作を試みて見た。

結果、samba 4.15.5ではWindowsのDNS管理ツールから行う「委任ウィザード」の「ネームサーバーレコード」の登録で「検証エラー」が発生するためうまく動作しなかった。

sa

samba-tool コマンドでNSレコードの登録を行ってみたところ登録ができるが、指定したDNSサーバに聞きに行くわけではない、という動作だった。

同じ操作をWindows Server 2019で作ったActive Directory環境で試すと何も問題が無く設定完了した

IPMIを有効にしたPowerScaleでipmitoolによる電源ON/OFF

このエントリーをはてなブックマークに追加

PowerScale/IsilonではIPMIを有効にする必要性はない。

しかし、UPS連動をちゃんと行おうとすると、IPMI経由で電源ON/OFF制御が行えるようにしておいた方が良い。

IPMIを有効にするあたりのことはDELLコミュニティにある「PowerScale IPMI編」を参考のこと。

使用するipmitoolのコマンドは下記のような感じとなる。

$ ipmitool -I lanplus -H IPアドレス -U admin -L OPERATOR -P パスワード power status
$ ipmitool -I lanplus -H IPアドレス -U admin -L OPERATOR -P パスワード power off
$ ipmitool -I lanplus -H IPアドレス -U admin -L OPERATOR -P パスワード power on

ためしに電源ステータスを確認すると下記の様になった。

$ ipmitool -I lanplus -H IPアドレス -U admin -L OPERATOR -P パスワード power status
Chassis Power is on
$

なお、ipmitool側から接続先のIPアドレスがどのノードであるかを確認する手法はないようなので、事前にPowerScale上で「isi ipmi nodes list」コマンドを実行し、IPMIのIPアドレス一覧を取得しておく必要がある。

isilon-1# isi ipmi nodes list
Lnn  IP Addr      Remote Ipmi Capable
--------------------------------------
1    192.168.1.11 Yes
2    192.168.1.14 Yes
3    192.168.1.12 Yes
4    192.168.1.13 Yes
5    192.168.1.15 Yes
6    192.168.1.17 Yes
7    192.168.1.18 Yes
8    192.168.1.16 Yes
--------------------------------------
Total: 8
isilon-1#

この時注意が必要なのは、IPアドレスがLnnの番号とは関係無く割り当てられているということ。

一度割り当たると、ノード物理交換でも無い限りは割当が変更されないようなので、一度確認しておけばよい感じではある。

PowerScale でアラートの警告をCLIで消す

PowerScale/Isilon/One FSシミュレータをvSphere環境上にたてて放置しておいたら、アラートが上がっている。

One or more drives (location(s) Bay 7, Bay 8, Bay 9, Bay 10, Bay 11, Bay 12, Bay 13, Bay 14, Bay 15 / type(s) HDD, HDD, HDD, HDD, HDD, HDD, HDD, HDD, HDD) are not healthy.

各ノードのBayについて出ている。

[Cluster Management]-[Hardware Configuration]の[Drives]で該当ノードをスロットを確認するとたしかに「Empty」となっている。

sshアクセスして「isi status」の結果をとってみる。

出力の「Lnn」に注目してもらうと見えてくるのですが、isi statusで出ている2,7以外でもこのメッセージは出ていて、それはすでにResolveとしていたりします。

Lnn単位でフィルターするオプションはないようなので、grepします。

「isi status」で確認した時刻「03/15 19:23:19」を使います。

format=csvの時の時刻はunixtimeとなっているのでdateコマンドを使って変換します。ただし、OneFSのdateコマンドはBSD dateなのでオプションの違いに注意する必要があります。
