Proxmox VEのcephストレージ環境の動作を確認するためESXi上に RAM 16GBの仮想マシンを4台作ってテスト中(+1台 corosync qnetdサーバがいてProxmox VEクラスタの維持に使用)

で、あるタイミングから、各ノード上のosdのdownが多発するようになった

が・・・またしばらくすると、他のosdが落ちる、などしていた

RedHat Ceph Storage 7 トラブルシューティングガイドの「第5章 Ceph OSD のトラブルシューティング」5.1.7. OSDS のフラップ を確認すると、osdに指定されているディスクが遅いから、ということになるようだ。

osd_heartbeat_grace_time というパラメータをデフォルトの20秒から変更すると、タイムアウトまでの値を緩和できるのかな、と思ったのだが、どうやって設定するのかが不明…

ceph.orgのOSD Setting を見ると /etc/ceph/ceph.conf (PVEの場合、 /etc/pve/ceph.conf )に追加すればいいのかな？というところなんだけど、OSD Config Reference , Configuring Monitor/OSD Interaction を見ても osd_heartbeat_grace_time というパラメータが無い…(osd_heartbeat_grace ならあった)

RedHatドキュメントの続きに書いてある「この問題を解決するには、以下を行います。」のところを見ると、「ceph osd set noup」「ceph osd set nodown」を設定して、OSDをdownおよびupとしてマークするのを停止する、とある。

試しにnoup,nodownの療法を設定してみたところ、OSDサービスを起動してもceph osd df treeで確認するとdownのままとなっていた。

まあ、upになったとしてもupのマークを付けないのが「noup」だから当然ですね・・・

そんなわけで、「ceph osd unset noup」「ceph osd set nodown」でdownにしない、という設定を入れてみた

設定を入れると「ceph osd stat」での状態確認で「flags nodown」と表示されるようになる。

root@pve38:~# ceph osd stat
16 osds: 16 up (since 62m), 16 in (since 62m); epoch: e4996
flags nodown
root@pve38:~#

とりあえず、これで一時的なごまかしはできた。

ただ、これは、OSDで使用しているディスクが壊れたとしても downにならない、ということでもある。

なので、「nodown」フラグを設定しっぱなしで使う、というのはとても不適切となる。

ちゃんとした対処を行うためには、具体的に何が問題になっているのかを「ceph health detail」を実行して、具体的にSlow OSD heartbeats がどれくらい遅いのかを確認する

osd.7のログが出てるpve37にログインして /var/log/ceph/ceph-osd.7.log から「no replay from」と「osd.8」でgrep をかけてログを確認

おそらく「Slow OSD heartbeats on front from osd.8 [] to osd.7 [] 2436.661 msec」に相当するあたりがコレなのかな？というところ

oldset deadlineにある時刻と、その前にある時刻の差は20秒なので、 osd_heartbeat_grace もしくは osd_heartbeat_grace_time のデフォルト値 20 が効いてるんだろうなぁ、と推定できる

設定手法について記載を探してみたのだがなかなかない

 Ceph Block Device 3rd Party Integration »  Ceph iSCSI Gateway »  iSCSI Gateway Requirements に下記のような設定例がある

[osd]
osd heartbeat grace = 20
osd heartbeat interval = 5

また、下記のように個別OSDに対して値を設定することも可能であるようだ

ceph tell osd.* config set osd_heartbeat_grace 20
ceph tell osd.* config set osd_heartbeat_interval 5

ceph daemon osd.0 config set osd_heartbeat_grace 20
ceph daemon osd.0 config set osd_heartbeat_interval 5

ceph tellの書式を確認すると「ceph tell osd.* config get osd_heartbeat_grace」で値がとれる模様

root@pve37:~# ceph tell osd.* config get osd_heartbeat_grace
osd.0: {
    "osd_heartbeat_grace": "20"
}
osd.1: {
    "osd_heartbeat_grace": "20"

とはいえ、set時の出力に「(not observed, change may require restart)」とあるとおり、ceph-osdの再起動が必須であるようだ

/etc/pve/ceph.conf に変更したパラメータは反映されてない模様なので、 osd.4～osd.7があるサーバを再起動してからもう一度値を確認してみたら、20に戻っていた。

root@pve38:~# ceph tell osd.* config get osd_heartbeat_grace

/etc/pve/ceph.conf の最後に下記を追加

[osd]
        osd heartbeat grace = 30

設定後、再起動してから確認すると、想定通り30になっているのを確認。そもそも、osd_heartbeat_grace についてはceph tellコマンドでの設定変更後、再起動しないでも大丈夫、というやつなんでは？

Proxmox VEクラスタをUPSで停止する手法のメモ(調査段階

Check
Facebook にシェア
このエントリーをはてなブックマークに追加

Proxmox VE環境でcephによるストレージ領域を作成して、物理的にディスクを共有していない状態で複数サーバ間を1ファイルシステムで運用できる環境についての試験中。

Proxmox VEクラスタをUPS連動で停止する場合の処理について確認しているのだが、公式ドキュメントにそのまま使えるようなものがないので、情報を集めているところ・・・

Proxmox VE公式ドキュメント:Shutdown Proxmox VE + Ceph HCI cluster
これはceph側の処理だけかかれていて、ceph側を止める前には仮想マシンを停止しなければならないのに、そこについて触れていない。

Proxmox VEフォーラムを探す
Clean shutdown of whole cluster (2023／01／16)
Shutdown of the Hyper-Converged Cluster (CEPH) (2020/04/05)

ここらのスクリプトが使えそうだが、仮想マシン/コンテナを停止するのは「各ノードで pvenode stopallを実行」ではなく、「APIを使ってすべてを停止する」が推奨される模様。

ここから試験

「pvesh get /nodes」でノードリストを作って、「ssh ホスト名 pvenode stopall」で仮想マシンを停止できるか試してみたが、管理Web上は「VMとコンテナの一括シャットダウン」と出力されるのだが、仮想マシンの停止が実行されなかった。

3.11.3. Bulk Guest Power Management を見ると止まっても良さそうなんだけど・・・

pvesh コマンドを調べるとこちらでも停止させることができる模様なので下記で実施

for hostname in `pvesh ls /nodes/|awk '{ print $2 }'`; do for vmid in `pvesh ls /nodes/$hostname/qemu/|awk '{ print $2 }'`; do pvesh create /nodes/$hostname/qemu/$vmid/status/shutdown; done; done

実行例

root@pve36:~# for hostname in `pvesh ls /nodes/|awk '{ print $2 }'`
> do for vmid in `pvesh ls /nodes/$hostname/qemu/|awk '{ print $2 }'`
>   do
>     pvesh create /nodes/$hostname/qemu/$vmid/status/shutdown
>   done
> done

これで、停止することを確認

root@pve36:~#

“stopped” となってない行があればまだ停止していない、ということになるので「pvesh get /nodes/pve36/qemu –noborder –noheader|grep -v “stopped”」の出力結果があるかどうかで判断できそう

また、これらはqemu仮想マシンについてのみなので、lxcコンテナについては含まれないので、そちらについても対応する

停止

for hostname in `pvesh ls /nodes/|awk '{ print $2 }'`; do for vmid in `pvesh ls /nodes/$hostname/lxc/|awk '{ print $2 }'`; do pvesh create /nodes/$hostname/lxc/$vmid/status/shutdown;done;done

仮想マシンが止まったかを判断するには、すべての仮想マシンの状態が”stopped”になっているか、で判定するなら下記

for hostname in `pvesh ls /nodes/|awk '{ print $2 }'`; do  echo "=== $hostname ===";    flag=0;  while [ $flag -eq 0 ];  do    pvesh get /nodes/$hostname/qemu --noborder --noheader|grep -v "stopped" > /dev/null;    flag=$?;    echo $flag;  done; done

すべての仮想マシンの状態で”running”がないことなら

for hostname in pvesh ls /nodes/|awk '{ print $2 }'; do echo “=== $hostname ===”; flag=0; while [ $flag -eq 0 ]; do pvesh get /nodes/$hostname/qemu –noborder –noheader|grep “running” > /dev/null ; flag=$?; echo $flag; done; done

どっちがいいかは悩むところ

Cephの停止についてはRedHatの「2.10. Red Hat Ceph Storage クラスターの電源をオフにして再起動」とProxmoxの「Shutdown Proxmox VE + Ceph HCI cluster 」を確認

Proxmox VE側だと下記だけ

ceph osd set noout
ceph osd set norecover
ceph osd set norebalance
ceph osd set nobackfill
ceph osd set nodown
ceph osd set pause

RedHat側にはこれらを実行する前にcephfsを停止するための手順が追加されている。

ceph fs set FS_NAME max_mds 1
ceph mds deactivate FS_NAME:1 # rank 2 of 2
ceph status # wait for rank 1 to finish stopping
ceph fs set FS_NAME cluster_down true
ceph mds fail FS_NAME:0

ceph fs setで設定しているmax_mdsとcluster_downの値はどうなっているのかを確認

root@pve36:~#

joinableを使えとあるので、この記述は古いらしい

おや？と思って再度探したところRedHatのドキュメントが古かった。RedHat「2.5. Red Hat Ceph Storage クラスターの電源をオフにして再起動」、もしくはIBMの「Ceph File System ・クラスターの停止」

ceph fs set FS_NAME max_mds 1
ceph fs fail FS_NAME
ceph status
ceph fs set FS_NAME joinable false

IBM手順の方だとmax_mdsの操作は行わずに実施している

Debianベースの商用ディストリビューションeLxr (エリクサー)

Check
Facebook にシェア
このエントリーをはてなブックマークに追加

ITmediaに「CentOS後継の“本命”となるか　ウインドリバーCTOが語る最新Linuxディストリビューションの狙い」という記事が掲載されていた。

RHELベースのディストリビューションかな？と読み進めてみると、組み込み向けでシェアを持ってるWind RiverがDebianベースで出した商用ディストリビューション eLxr Proの宣伝記事だった。

年間いくらのライセンス料金？とページを見てみるも「お問い合わせ」しかなく価格帯不明。

英語版eLxr Proのページを見てみると、もうちょっと内容があってFAQに eLxr project が紹介されていたが価格については見当たらず、StoreにもeLxr関連の記述がない。

記事を探すとZDnet「ウインドリバー、企業向けLinux商用版の国内提供を発表–エッジ領域などに展開」にて、年間7万円から、という記載があった。

　eLxr Server Proおよびサービスは、仮想／物理サーバー1台当たりの年間契約のサブスクリプションになり、サポート内容に応じた2つのメニューをそろえる。標準メニューの「Enterprise」の料金は年間7万円から、Enterpriseの内容に加え高度なSLAに基づく技術サポートや通信事業者レベルのサポートを追加する「Priority」が同15万2000円からとなっている。

RHELのサイオステクノロジーでの価格が年間約13万円~ と比較すると安いけど・・・

本題と外れるが、CentOS の代替としてRHEL系Linuxを選ぶ場合に検討対象となるのは以下になるであろう

・RedHat Enterprise Linux (RHEL)
　まあ、公式ですが、お値段が問題となる
・Alma Linux か Rocky Linux
　現状、どちらにすべき、というコレといったものがないので、好みやサポートを買える場所があるかどうかで選ぶ。例えば下記のような動きとか
　　Rocky Linuxを作る主体のCIQ社はOracleとSUSEとくんでopenELAという団体を作った
　　Alma LinuxはAzure上の認定を取得した
・Oracle Linux
　有償だけど、無償でも十分使える
　Oracle DB/mysql/opensolaris周りのコレまでの事例を見てると、突然無償の範囲が変わりそうなのがちょっと恐い
　Oracle Cloud(OCI)上で動かしたいのでれば、Oracle Linuxにするべき

CentOS代替話であがってくるけど個人的にはあまりひかれないディストリビューション
・SUSE Liberty Linux
　CentOS7に対して2028年6月末まで、CentOS9に対して当分の間、パッチを提供する有償サービス
・MIRACLE LINUX
　無償でも使える日本語のRHEL互換。いまはサイバートラスト社で作ってる
　AlmaLinuxの開発にも関与しており、RHEL10の世代ではAlmaLinuxに合流する見込み
　　

それはさておき、eLxr projectの方では、コミュニティ版のインストールイメージが入手できるようになっていた。

というわけで、 eLxr Server version 12 for x86 (12.6.1.0) をESXi環境にインストールしてみた

現状のeLxr 12.6.1.0はSecure boot非対応なようで、有効状態の場合は下記のようなエラーとなって起動できない

Secure bootを無効にして、作業を進めていく

ホスト名関連

パスワードとユーザ

パーテーション設定

最後の質問

上記で「続ける」をクリックしたらインストールが開始された。

そして、インストール終了

再起動

ログイン

標準状態ではopenssh-serverがインストールされていないので、sshログインして使うのであれば「apt install openssh-server」を実行してインストールを行う必要がある。

サポート必要とするDebianがほしいならeLxrを選んでも良い、という気はするが・・・

LLM環境とかGPU関連で使うのであれば、Ubuntuで用意されている追加のレポジトリが前提になってたりもするので、そこら辺がないディストリビューションを使う意義が感じにくいなぁ、と

proxmoxの外部corosyncサーバに使えるかな？と思ったんだけど、レポジトリに corosync-qdeviceがありませんでした

2024/11/05追記

ドキュメントサイトを見直したら「eLxr 12 Quick Start – Adding and Updating Packages」に /etc/apt/sources.list に対してdebianのレポジトリ追加する、

root@elxr:/etc/apt# cat sources.list
deb [trusted=yes] https://mirror.elxr.dev/elxr aria main

追加したあとで、先ほどなかったcorosync-qdeviceを探してみるとdebianのほう起因で出てきた。

proxmox 8.1.4で適当にcephストレージ作ったらWARNINGが出た件の対処

Check
Facebook にシェア
このエントリーをはてなブックマークに追加

proxmox 8.1.4でサーバを３台インストールして、cpehストレージ作ってみるかー、と適当に設定した。

基本は「Deploy Hyper-Converged Ceph Cluster」を見ながらやったんだけど、CephFSを作成するときに、手順だと「pveceph fs create –pg_num 128 –add-storage」と書いてあったんだけど、「pveceph fs create」だけで実行したらどうなるんだろ？と思ってやってみたところ、警告が出た

注:なお、結局のところ、指定しない場合のデフォルト値も128だった。

HEALTH_WARN: 1 pools have too many placement groups
Pool storagepool has 128 placement groups, should have 32

調べてみるとproxmoxのフォーラムに「CEPH pools have too many placement groups」という若干古め(2020年のpoxmox 6.3時代)のものが見つかった。

「pveceph pool ls」で現在の設定を確認

poolによって差がありすぎている？

中国語のページで「ceph使用问题积累」というところがあって「HEALTH_WARN：pools have too many placement groups」と「HEALTH_WARN： mons are allowing insecure global_id reclaim」についての対処方法が載っている。

前者については↑で出てきたproxmoxフォーラム記事を参照元として「ceph mgr module disable pg_autoscaler」を実行してauto scale機能を無効化する、とある

後者については「ceph config set mon auth_allow_insecure_global_id_reclaim false」となっていた。

TOO_MANY_PGSの時の対処としていかが書かれている

TOO_MANY_PGS
The number of PGs in use is above the configurable threshold of mon_pg_warn_max_per_osd PGs per OSD. This can lead to higher memory usage for OSD daemons, slower peering after cluster state changes (for example OSD restarts, additions, or removals), and higher load on the Ceph Managers and Ceph Monitors.

While the pg_num value for existing pools cannot be reduced, the pgp_num value can. This effectively co-locates some PGs on the same sets of OSDs, mitigating some of the negative impacts described above. The pgp_num value can be adjusted with:

proxmox「Deploy Hyper-Converged Ceph Cluster」のあたりをみると PG Autoscale Modeはwarnで設定されるのが標準であるようだ。

cephのautomated scalingを見ると「ceph config set global mon_target_pg_per_osd 100」で値を設定することが書かれているが、現在値の確認方法が書いてない。

ceph config get <who> <key>というのはわかったのだが、whoの部分がなんなのかがわからなかった。(globalではなかった)

「ceph config dump」を実行したところ、いま標準値から変更されているところであろう設定が出てきて、whoに該当するものとしてmonがあった。であればmon_target_pg_per_osdのwhoはmonだろうと試すと現在値らしきものが確認できた。

root@zstack137:~# ceph config dump
WHO  MASK  LEVEL     OPTION                                 VALUE  RO
mon        advanced  auth_allow_insecure_global_id_reclaim  false
root@zstack137:~# ceph config get mon  mon_target_pg_per_osd
100
root@zstack137:~#

とりあえず、「ceph mgr module disable pg_autoscaler」を実行してみたのだが、変更不可だった

root@zstack137:~# ceph mgr module disable pg_autoscaler
Error EINVAL: module 'pg_autoscaler' cannot be disabled (always-on)
root@zstack137:~#

じゃあ、「ceph osd pool set storagepool pgp_num 32」を実行してpgp_numを128から32に変更してみる

root@zstack137:~# ceph osd pool stats
pool .mgr id 1
  nothing is going on

pool cephfs_data id 2
  nothing is going on

pool cephfs_metadata id 3
  nothing is going on

pool storagepool id 4
  nothing is going on

root@zstack137:~# ceph osd pool get storagepool pgp_num
pgp_num: 128
root@zstack137:~# ceph osd pool set storagepool pgp_num 32
set pool 4 pgp_num to 32
root@zstack137:~# ceph osd pool get storagepool pgp_num
pgp_num: 125
root@zstack137:~# ceph osd pool get storagepool pgp_num
pgp_num: 119
root@zstack137:~#

徐々に変更されていく模様

Windows Updateしたらsamba ADへの接続がおかしくなった

Check
Facebook にシェア
このエントリーをはてなブックマークに追加

sambaで作ったsamba AD環境がある。

最近、新しい仮想マシン作ってドメイン参加したあと、PowerShellで「Test-ComputerSecureChannel」を実行したら「False」と出た。

repairしても状況が変わらない

(ADサーバと該当マシン間の通信がセキュアチャネルを使って行われていないという状態)

いまつかっているsambaバージョンを確認すると4.18.2

# /usr/local/samba/sbin/smbd --version
Version 4.18.2
#

sambaのリリース履歴を見るとNetAppでも問題になったセキュリティ修正関連での修正が出ている。

CVE-2023-34967, CVE-2022-2127, CVE-2023-34968, CVE-2023-34966 and CVE-2023-3347.

直接のバグとしては「Bug 15418 – secure channel faulty since Windows 10/11 update 07/2023」が該当している模様

バグであるならアップデートするしかないな、というわけで、samba 4.18.5へアップデート

展開して、make;make install; systemctl restart samba-ad-dc っと

# /usr/local/samba/sbin/smbd --version
Version 4.18.5
#

で、repairすると、今度は成功しました
