1032422 - plugins dbs need more RAM

Status: RESOLVED FIXED

(Infrastructure & Operations :: Virtualization, task)

Description

[Brandon Johnson [:cyborgshadow]]

Please allocate an additional 2GB RAM to the plugins virtualized databases.

Please coordinate with the db team when you're free to do the work and we can rotate the servers in the load balancer.

So, I've got these as plugins{1-2}.db.phx1.mozilla.com

Looking at them, I totally see that 2 needs more ram.  But 1 appears comfortable, primarily due to its having twice as much RAM.

$ for i in 1 2 ; do echo "plugins$i:"; ssh root@plugins$i.db.phx1.mozilla.com free -m ; done
plugins1:
             total       used       free     shared    buffers     cached
Mem:          7872       6247       1624          0        357       2185

Swap:         2047          0       2047
plugins2:
             total       used       free     shared    buffers     cached
Mem:          3833       3425        408          0         60        195

Swap:         2047        120       1927

Based on this, I would love to match 2 to 1, bumping it by 4GRAM.  I'm available most anytime between 8am and 5pm Eastern.  Just poke at me on IRC.

Been a couple weeks - haven't heard anything - is this something you still want?

Comment 3

[Chris Knowles [:cknowles]]

Alright, plugins2.db.phx1 now has 8GRAM and matches it's buddy.

Let me know if you need anything else here.

Plugins is a happy cluster.
