If you’re like me, you spend so much time typing on a computer that a good notebook or journal is one of life’s finer pleasures. I’ve kept a diary of my personal life for close to 30 years now, and I have a shelf full of journals. I’ve found a great many that I enjoy writing in, and choosing a different one each time is part of the fun.
For 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 I saw that, but here it was obvious. So I recorded some metrics, bi from vmstat and percent of cow space used from lvs during a backup. Cow space is the Copy On Write buffer used by LVM to record the modified pages like they were at the beginning of the snapshot.
