Everyone,
I am putting together a new mail server for our firm using a SuperMicro with Centos 7.0. When performed the install of the os, I put 16 gigs of memory in the wrong slots on the mother board which caused the SuperMicro to recognize 8 gigs instead of 16 gigs. When I installed Centos 7.0, this error made the swap file 8070 megs instead of what I would have expected to be a over 16000 megs.
I am using the default xfs file system on the other partitions. Is there a way to expand the swap file? If not, then is this problem sufficiently bad enough for me to start over with a new install. I do not want to start over unless I need to.
8G of swap should be more than enough for a 16G system unless you plan to severely over-commit memory.
