ZFS分区扩容

ZFS分区扩容
使用虚拟机时需要进行磁盘的动态扩容

扩容本地分区

查看磁盘分区情况

$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 120G 0 disk
├─sda1 8:1 0 512M 0 part /boot/grub
│ /boot/efi
├─sda2 8:2 0 2G 0 part [SWAP]
├─sda3 8:3 0 2G 0 part
└─sda4 8:4 0 65.5G 0 part

扩容sda4

parted /dev/sda resizepart 4 100%

partprobe

扩容zpool
查看zpool状态，得到zpool名称以及加入到zpool的硬盘名称：
root@mint-vm:/home/mint# zpool status
pool: bpool
state: ONLINE
config:

NAME                                    STATE     READ WRITE CKSUM
bpool                                   ONLINE       0     0     0
  c93fe93f-09d3-6245-aafb-7d6ad98fbd05  ONLINE       0     0     0

errors: No known data errors

pool: rpool
state: ONLINE
config:

NAME                                    STATE     READ WRITE CKSUM
rpool                                   ONLINE       0     0     0
  4af7ba7e-639e-b841-9306-c7edb9c55c0a  ONLINE       0     0     0

errors: No known data errors

得到zpool的名称为rpool, 当前挂载的硬盘为4af7ba7e-639e-b841-9306-c7edb9c55c0a.

然后执行扩容命令：

zpool online -e rpool 4af7ba7e-639e-b841-9306-c7edb9c55c0a
