            Bug ID: 67926
           Summary: Replace role::labs::lvm::biglogs with increasing the
                    default /var partition
           Product: Wikimedia Labs
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW

          Priority: Unprioritized
         Component: General

Bug #67912 showed that role::labs::lvm::biglogs is fundamentally broken: You
can't move around/shadow /var/log in a running system.

I thought about some super-duper OpenStackManager UI where you could specify
the partitioning and during reboots OpenStack would shuffle the files and
volumes accordingly, so that you always have a clean system, when Yuvi pointed
out a far superior solution:

If we increase the size of the default /var partition by (for Tools, other
projects may need more) 2 GByte, we wouldn't have to think about all that
complex stuff, because (at Tools) /var/log is usually less than 2 GBytes big.

With the same step, we might want to set up a separate /tmp partition (could be
even ramdisk) to avoid the problems of people filling that up as well.

This will require a bit of disk space at virt*, and it will not solve all
partitioning needs there are at Labs, but I think it is a quick solution for 90
% that could last a long time.
