• Puppet, Nagios, Munin on cPanel based hosts

  - by WinkyWolly

  I've been managing 20-30~ cPanel based hosts over the past year with Puppet, Nagios and Munin for general monitoring / trending however a lot of the methods I've had to use to deploy / manage things such as configurations a pain. For those of you who aren't familiar with cPanel - it adds a few things to yum exclude such as perl*, ruby* and so forth. This causes issues with me being able to bootstrap monitoring on a new server via Puppet (well via the Package type) due to a bunch of conflicts with installing via Yum. Now I could create a custom RPM for everything and remove certain dependencies from the spec file however I would like to avoid this if possible. Does anyone have any proposed functional ways to manage this sort of environment? Currently I install Puppet, Facter and Munin via RPM's and force install using --nodeps and such (since they're installed, just no the ones Yum wants). Nagios I installed manually from source at this time (likely will create RPM's however I want to tackle this general issue first).

• Optimal way to make MySQL backups for fairly large databases (MyISAM / InnoDB)

  - by WinkyWolly

  Currently we have one beefy MySQL database that runs a couple of high traffic Django based websites as well as some e-commerce websites of decent size. As a result we have a fair amount of large databases using both InnoDB and MyISAM tables. Unfortunately we've recently hit a wall due to the amount of traffic so I've setup another master server to help alleviate reads / backups. Now at the moment I simply use mysqldump with a few arguments and it's proven to be fine.. until now. Obviously mysqldump is a slow quick method however I believe we've outgrown its use. I now need a good alternative and have been looking into utilizing Maatkits mk-parallel-dump utility or an LVM snapshot solution. Succinct short version: I have a fairly large MySQL databases I need to backup Current method using mysqldump is inefficient and slow (causing issues) Looking into something such as mk-parallel-dump or LVM snapshots Any recommendations or ideas would be appreciated - since I have to re-do how we're doing things I rather have it done properly / most efficient :).

• MCollective alternative?

  - by WinkyWolly

  I really want to run MCollective on my fleet of servers however there are a large number of untrusted users on each machine which makes using MCollective not ideal in my eyes. I'm aware that there is some things you can do to take precaution but I'm not familiar enough with ActiveMQ / want something that's a bit more mindful of similar environments to mine outside the box. I'm looking for a fact collection like tool essentially. (Tagging under puppet / server since no mcollective tag and I don't have enough reputation to create a new one)

• Colocation and HSRP setup

  - by WinkyWolly

  My colocation provider has setup HSRP for us and has provided us 2 drops (plugged into 1/1/1 and 1/1/2) from their routers as well as a /29 with 2 HSRP IP's and the rest of the /29 usable for the switch. I know that HSRP should be pretty much plug and play as long as the ports are in the same VLAN. However I'm confused as to how to the IP setup should work. Currently I've assigned port 1/1/1 the full /29 however I think this is incorrect because if I were to unplug it port 1/1/2 wouldn't work as it has no IP assignment. What's the proper way to do this?

• Using FlashCache on /var on startup

  - by WinkyWolly

  I would like to have FlashCache cache my /var partition however I can't seem to get it to play nice upon bootup (IE: not really sure how to do it). I'm not sure if I need to modify the initramfs/use DKMS or if I can do it in user-land during bootup. The issue I'm running into is /var mounts early and therefore the device is busy (whether it by generally by syslogd). I'm positive this can be resolved by modifying the initramfs although I simply haven't fiddled with it enough to get it working. They have instructions on how to boot your root partition however I'm not sure if these instructions would apply to my use case. Any help / pointers in the right direction would be absolutely splendid.

• Accountability in a cloud infrastructure (Amazon, etc)

  - by WinkyWolly

  I was curious how companies such as Amazon would handle some sort of investigation that needed to look into data potentially stored on one of their on-demand nodes. What typically happens to data in an environment like this after the VM is destroyed (literally what happens on the disk / FS)? Would it actually be possible to recover data from a destroyed node? Just a curiosity :)

• Python CLI tool - general parsing question

  - by WinkyWolly

  If possible I would like to use the following structure for a command however I can't seem to figure out how to achieve this in Python: ./somescript.py arg <optional argument> -- "some long argument" Would it be possible to achieve this in a feasible manner without too much dirty code? Or should I just reconsider the syntax (which is primarily preference). Thanks!
