The SPARSEBUNDLE type means the filesystem will grow in 1M pieces, it won't immediately allocate 300GB. 300GB is the limit and you can resize it later if you need to. Stellar has a 256GB drive and right now has 115GB on it. After executing this command, the empty bundle consumed 430M of space. I remember when 430M was a huge amount of space. :-) | The SPARSEBUNDLE type means the filesystem will grow in 1M pieces, it won't immediately allocate 300GB. 300GB is the limit and you can resize it later if you need to.

History
2016-Jan-20 set up as Time Machine
Hardware
Hardware is a MiniITX server that used to be Bellman
The two Seagate Green 2TB drives are now striped because I need space more than reliability for Time Machine.
Changing over from mirror to stripe
It ended up on /dev/md126 (he shrugs).

# Must Haves apt-get install emacs
Netatalk
Installing Netatalk makes Tern visible as an Apple server.

Built deb packages for netatalk from git on bellman and install packages here.
apt-get install mysql-common libcrack2 libmysqlclient18 avahi-daemon dpkg --install libatalk16_3.1.7-1_amd64.deb netatalk_3.1.7-1_amd64.deb emacs /etc/netatalk/afp.conf systemctl enable avahi-daemon systemctl enable netatalk systemctl start avahi-daemon systemctl start netatalk
Contents of afp.conf file
The "valid user" is the name of a user in the local passwd file on Tern.

Time Machine, on the MAC
You have to allow TimeMachine to write to an "unsupported volume" with this command
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
On Stellar only, for some reason I had to manually create a sparse bundle on the server to make it work. Connect to server from Finder. Swift and Plover had no problems creating their own bundles. Then in Terminal,
hdiutil create -size 300G -type SPARSEBUNDLE -verbose -fs HFS+J -volname "Time Machine" /Volumes/Timemachine_Stellar/stellar.sparsebundle
The SPARSEBUNDLE type means the filesystem will grow in 1M pieces, it won't immediately allocate 300GB. 300GB is the limit and you can resize it later if you need to. Stellar has a 256GB drive and right now has 115GB on it. After executing this command, the empty bundle consumed 430M of space. I remember when 430M was a huge amount of space. :-)
