Enable Ubuntu 19.04 Server to start over LAN (Wake-on-LAN)
History
I decided to suspend the file server during the daytime on weekdays to save electricity, so I have to manually cancel the suspend on a public holiday weekday. This itself is unavoidable, but at least, I want to be able to turn on remotely via LAN from the main machine rather than the power button . So I try the fanction called Wake-on-LAN.

Suspend file server (ubuntu 19.04) only during weekday daytime
Purpose
I am running my file server, but it is not used during the daytime of the weekday. So I’m going to suspend it when I don’t use.

Install ZFS to Ubuntu Server 19.04 and build RAID1
Circumstance
Less than half a year to move the PC to homebrew NAS. Because of lack of budget, My NAS has single HDD,
but now, I want to buy additional HDD and build mirroring to save my dataAt first, i was going to build a raid1 with ext4 and motherboard function, but after research, I decided to install a file system called ZFS. The reasons are following,
- The file system itself supports RAID
- Many useful functions such as transparent compression and snapshots
- It eats cpu and memory, On the other hand, I can think that make good use of my NAS’s specs.
