MySQL on XFS

Thu, 11 Apr 2013 00:00:00 +0000

XFS handles database workloads better than ext4 – better concurrent I/O, more efficient metadata operations for tables-heavy schemas, and delayed allocation that improves write throughput. The obvious approach is to change MySQL’s datadir in the config. The less obvious approach is bind mounts, which keep every path where the system expects it.

Setup

Install XFS utilities alongside MySQL:

sudo apt-get install -y xfsprogs mysql-server

Create the filesystem on the dedicated volume:

Linux on vnykmshr
