== Ikt to Mox (2020) home directories ==

You're responsible for moving your home directories from Ikt to Mox. To do so, follow these instructions:

=== 1. on IKT: prepare your homedirectory ===

First, go through and delete the things you don't want in your home directory. the program ncdu is installed on ikt and it will show you detailed information of what is taking up space. go through and recursively delete thing you don't want. if you want to archive things on cold storage, you can do that too by putting compressed tar files in /com/STAGING-cold_storage (we're strongly encouarged to ensure that each file is more than 100MB).

There are likely many hidden files as well. You can see those with "ls -a".

=== 2. on IKT: make a tarball of your home directory ===

You will need to make a tarball of your home directory and store it in <code>/com/STAGING-bbcp</code>

{{note}} change every instance of "'''<YOURUWNETID>'''" to your NetID (e.g., "makohill") before running the instructions below

<syntaxhighlight lang='bash'>
$ ssh login2.hyak.uw.edu
$ cd /usr/lusers
$ tar cvf /com/STAGING-bbcp/<YOURUWNETID>_ikt_homedir.tar <YOURUWNETID>
</syntaxhighlight>

=== 3. on IKT: copy the file over to your new homedirectory on MOX ===

<syntaxhighlight lang='bash'>
$ cd /com/STAGING-bbcp
$ hyakbbcp <YOURUWNETID>_ikt_homedir.tar mox1.hyak.uw.edu:/usr/lusers/<YOURUWNETID>/
</syntaxhighlight>

=== 4. on MOX: unpack you new data ===

Run the following:

<syntaxhighlight lang='bash'>
$ cd /usr/lusers/<YOURUWNETID>
$ tar xvf <YOURUWNETID>_ikt_homedir.tar --transform 's/^<YOURUWNETID>/ikt_homedir/'
$ rm ~/<YOURUWNETID>_ikt_homedir.tar
</syntaxhighlight>

This will create a new directory called <code>ikt_homedir</code> in my home directory on mox. I'll then go through and move out the things from <code>ikt_homedir</code> into <code>../</code> your new home dirctory. 
Or just leave them there if you want.
