Zabbix applianceにHDDを追加

Zabbix applianceをVMware ESXi 6.7に導入してサーバ，ネットワーク機器の監視をはじめました｡

Zabbix applianceをVMware ESXi 6.7にセットアップ

一通りの設定を終えてHDDの空き容量を見たら1.8GBでした｡

監視端末が少ないとは言え､さすがにこれでは1年も持たないのは見えているので新規HDDを追加しました｡

手順は下記の記事を参考にして下さい｡

Linux LVM HDDの追加(パーティション拡張)

1. 仮想HDDの新規追加

ESXi 6.7のWeb Clientにログインして仮想マシンの編集を行います｡[ハードディスクの追加]から新規に50GBのディスクを追加しました｡




追加後に仮想マシンを起動､あるいは再起動すると/dev/sdbとして認識します｡

2. fdiskでLVMパーティションを作成
Shell

appliance@zabbix:~$ sudo fdisk /dev/sdb Welcome to fdisk (util-linux 2.27.1). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Device does not contain a recognized partition table. Created a new DOS disklabel with disk identifier 0x7c5e81e3. Command (m for help): n Partition type p primary (0 primary, 0 extended, 4 free) e extended (container for logical partitions) Select (default p): p Partition number (1-4, default 1): First sector (2048-104857599, default 2048): Last sector, +sectors or +size{K,M,G,T,P} (2048-104857599, default 104857599): Created a new partition 1 of type 'Linux' and of size 50 GiB. Command (m for help): t Selected partition 1 Partition type (type L to list all types): 8e Changed type of partition 'Linux' to 'Linux LVM'. Command (m for help): w The partition table has been altered. Calling ioctl() to re-read partition table. Syncing disks.

3. 物理ボリューム(pv)を作成
Shell

appliance@zabbix:~$ sudo pvcreate -v /dev/sdb1 Set up physical volume for "/dev/sdb1" with 104855552 available sectors Zeroing start of device /dev/sdb1 Writing physical volume data to disk "/dev/sdb1" Physical volume "/dev/sdb1" successfully created appliance@zabbix:~$ sudo pvscan PV /dev/sda5 VG zabbix-vg lvm2 [9.29 GiB / 0 free] PV /dev/sdb1 lvm2 [50.00 GiB] Total: 2 [59.28 GiB] / in use: 1 [9.29 GiB] / in no VG: 1 [50.00 GiB]

4. ボリュームグループ(vg)に追加

zabbix-vgが59.28GBに拡張されました｡

Shell

5. 論理ボリューム(lv)の拡張
Shell

appliance@zabbix:~$ sudo -l +100%FREE /dev/zabbix-vg/root sudo: +100%FREE: command not found appliance@zabbix:~$ sudo lvextend -l +100%FREE /dev/zabbix-vg/root Size of logical volume zabbix-vg/root changed from 5.29 GiB (1353 extents) to 55.28 GiB (14152 extents). Logical volume root successfully resized.

6. ファイルシステムを拡張
Shell

appliance@zabbix:~$ sudo resize2fs /dev/zabbix-vg/root resize2fs 1.42.13 (17-May-2015) Filesystem at /dev/zabbix-vg/root is mounted on /; on-line resizing required old_desc_blocks = 1, new_desc_blocks = 4 The filesystem on /dev/zabbix-vg/root is now 14491648 (4k) blocks long.

7. サイズの確認

/ が55GBに拡張されました｡

Shell

appliance@zabbix:~$ df -h Filesystem Size Used Avail Use% Mounted on udev 2.0G 0 2.0G 0% /dev tmpfs 396M 5.7M 390M 2% /run /dev/mapper/zabbix--vg-root 55G 3.1G 49G 6% / tmpfs 2.0G 0 2.0G 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup /dev/sda1 472M 111M 337M 25% /boot

これで暫くは大丈夫かな｡
