Goodbye, Tumblr
I've retired all my Tumblr blogs, in light of the Yahoo purchase and recent censorship concerns.
I'll be doing all my writing on Rubenerd.com, where I'm also importing all my posts.
Cheers, Ruben

Super.
Today I learned about mdadm
mdadm is a tool for managing Linux Software RAID arrays.
It can create, assemble, report on, and monitor arrays.
It can also move spares between raid arrays when needed.
It can be found at http://www.kernel.org/pub/linux/utils/raid/mdadm/ or any of the kernel.org mirrors.
There is a git repository at http://neil.brown.name/git/mdadm or git://neil.brown.name/mdadm.
FAQ and other documentation can be found at http://www.linuxfoundation.org/collaborate/workgroups/linux-raid
It can also slice, and dice. Except the opposite.
Xen virt-install with cdrom boot images
If you just supply the minimum options:
virt-install paravirtualized guests cannot install off cdrom media
It must default to PV mode. For HVM, use this surprising option:
virt-install [..] --hvm [..]

Disable QEMU SDL in Packer
Assuming your builders type is qemu, you may have seen this:
Qemu stderr: Could not initialize SDL(No available video device) - exiting
One solution in the Packer json was to disable graphics:
qemuargs: [ "-nographics" ]
Alternatively, start it headless:
"headless": "true"
If you've set the following, you'll be able to VNC remotely instead. When porting back to Xen, change your /etc/ttys so you can use the serial console as well.
View Packer errors
Building a Packer image (how's that name for terrible Google juice):
==> qemu: Error launching VM: Qemu failed to start. Please run with logs to get more info.
So how do we run with logs? From Debugging Packer:
Packer has detailed logs which can be enabled by setting the PACKER_LOG environmental variable to any value
So in that case:
export PACKER_LOG=1
You can also define a logfile instead:
export PACKER_LOG_PATH="/var/log/packer"

Errors with scp
If you want to run scp on a non-standard port, you use the -P flag. So I did this:
scp file.img.xz -P 99999 [email protected]:/dest/path/
And what did I get?
ssh: connect to host example.com port 22: no route to host
Why was it ignoring my hypothetically impossible port 99999? Oh, wait.
scp -P 99999 file.img.xz [email protected]:/dest/path/

Checking running servers with netstat
A useful set of flags is the delightful "plunt"
# netstat -plunt
For example, on a PostgreSQL box with custom ports:
Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1077/sshd tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN 2288/postgres tcp6 0 0 :::22 :::* LISTEN 1077/sshd tcp6 0 0 ::1:5432 :::* LISTEN 2288/postgres
Find PostgreSQL data dir from PostgreSQL
Assuming you can access your database:
postgres=# SHOW data_directory
On Debian Wheezy with the official PostgreSQL repo, the default will show:
data_directory ------------------------------ /var/lib/postgresql/9.3/main (1 row)
Too easy :).

PostgreSQL invalid listen_addresses
So now when I restarted Postgres:
Error: Invalid line 603 in /etc/postgresql/9.3/main/postgresql.conf: \ >listen_addresses="localhost,10.0.1.2"
See the bug? Yes, double quotes instead of single. From postgresql.conf:
listen_addresses='localhost, 10.0.1.2'
It's been a long Monday!
PostgreSQL invalid IP mask
Getting the following error when trying to start Postgres:
UTC LOG: invalid IP mask "md5": Name or service not known
Turns out, it's because I forgot to define the subnet mask for the allowed IP, which meant the security setting was being interpreted. Weird behavior, I would have expected it to search after a backslash.
An example for pg_hba.conf:
host replication postgres 10.0.1.10/24 md5
And an example of my bad one:
host replication postgres 10.0.1.10 md5
