Hey folks,

due to a variety of reasons, I am running a single, master mysqllvm64
instance (c1.xlarge) - in fact it's actually slaved to an external
machine and until we can move all our stuff to the cloud, we won't add
any more slaves to the actual farm. Farm id is 1395.

In the meantime, I am crossing my fingers and trying to figure out a
way of saving the mysql data frequently. Apparently, as it's a single
instance and no slaves are running, scalr won't do backup. Only
bundling is possible right now.

I had set the bundling frequency to 2 hours (the snapshot takes about
30 minutes to upload) and it seemed to be working fine when out of the
blue Saturday night, I noticed the mysql server had essentially gone
away. The mysqld process had died but I couldn't even kill it no
matter how many "kill -9"s I did. In my experience, this kind of stuff
usually happens when the file system is hosed - I suspect /mnt/mysql-
data to be gone. I issued a reboot command - however, scalr terminated
the instance and started a new one.

After a couple of hours of work, I was able to get the new instance up
and running from the last available bundle. However, I noticed another
possible bug - the static IP assigned by scalr to the previous master
was not being attached to the new one. Yet, scalr definitely knew I
had enabled the elastic ip option for the role. In the end, I had to
attach the static IP manually.

Right now, my farm, still running at one instance, has a bundling
interval of 24 hours. I wonder if very frequent bundling can lead to
file system corruption. Anyone else experienced anything similar?

Finger crossed ...
