Home Server Notes

gistfile1.txt

Installed Debian stable from netinstall on a USB stick created with unetbootin.

Selected btrfs on a raw partitian, and a small swap partitian. I chose
to try btrfs out for the first time on this system because I want compression
(8Gb internal SSD). I also want the parity checks so that, hopefully, the system
can run for years without any corruptuion of any of the important files. I figured
it would be a good first use because I can easily do a bare-metal backup of the SSD, 
being that it's only 8gb, to another machine.

Deselected standard desktop, and just installed SSH and standard utilities.

Note: on this computer, the usb drive is the "first hard drive" so you must remove it 
after the installer is started so that GRUB is installed on the acutal hard drive
instead.


Added backports for wheezy http://backports.debian.org/Instructions/

Updated to latest kernel in backports because it's recommended for btrfs. I
would have done the same for btrfs-tools, but it isn't in backports (note, 
this will have to be manually updated in the future.:

     apt-get -t wheezy-backports install linux-image-3.12-0.bpo.1-686-pae


## Disk Compression
Before enabling disk compression, this is the disk usage:

    root@shack:/home/jay# btrfs fi df /
    Data: total=1.48GB, used=1021.06MB
    System, DUP: total=8.00MB, used=4.00KB
    System: total=4.00MB, used=0.00
    Metadata, DUP: total=376.62MB, used=65.06MB
    Metadata: total=8.00MB, used=0.00

I then changed the system's fstab line to the following to enable compression and ssd tweaks:

    UUID=24c3026b-b3cd-4b99-be1f-437d2cea5e4e /               btrfs   noatime,ssd_spread,compress     $

and rebooted (rather than remounting). To defragment all the files:

    find / -type f -exec btrfs filesystem defragment -v -czlib '{}' +

Note that the command normally posted around the internet:

    btrfs filesystem defragment -r -v -clzo /

doesn't actually compress all the files, just the root index. There are of course errors 
for non-regular files, but when it's done, I have halfed the install size (neat!):


    root@shack:/home/jay# btrfs fi df /
    Data: total=1.48GB, used=564.89MB
    System, DUP: total=8.00MB, used=4.00KB
    System: total=4.00MB, used=0.00
    Metadata, DUP: total=376.62MB, used=64.95MB
    Metadata: total=8.00MB, used=0.00


## Now, prepare the system to run Ownclud
