Raid 1
To create a RAID1 pool (or mirror), simply add the command mirror when creating or adding drives. For example:
sudo zpool create -f [new pool name] mirror /dev/sdb /dev/sdc
sudo zpool add [existing pool name] mirror /dev/sdd /dev/sde
zpool status
zfs list
zpool create -f myraid1 mirror /dev/sda1 /dev/sdb1
root@pve /root# zfs mount -a
模拟
zpool offline myraid1 sda
zpool status myraid1
zpool offline myraid1 sda
mkfs.ext4 /de/sda
zpool online myraid1 sda
zpool replace -f myraid1 sda
zpool online myraid1 sda
