Over the last year, the Ceph world drew me in. Partly because of my taste for distributed systems, but also because I think Ceph represents a great opportunity for MySQL specifically and databases in general. The shift from local storage to distributed storage is similar to the shift from bare disks host configuration to LVM-managed […]

Introduction In my last blog post, Internet of Things, Messaging and MySQL, I have showed how to start your own Internet of Things with Particle Photon board.

The system will be quite write intensive, so the main interest is the write performance on capacities close to full-size storage. After some research I picked several candidates (I show […]

Read MoreFor the same customer I am exploring ZFS for backups, the twin server is using regular LVM and XFS. On this twin, I have setup mylvmbackup for a more conservative backup approach. I quickly found some odd behaviors, the backup was taking much longer than what I was expecting. It is not the first time […]
