November 30, 20196 yr I recently added a second SSD to my cache pool. I was wondering what the recommended frequency for running btrfs balance/scrub is? Is this something I need to do weekly/monthly?
November 30, 20196 yr btrfs-scrub(8) recommends around once a month, but less is fine. https://github.com/kdave/btrfsmaintenance is a really nice set of scripts for other distros, but you can look at the timers and etc to figure out what a good frequency is. Follwing this, btrfs-scrub & btrfs-balance are run monthly.
November 30, 20196 yr Author Thanks, thats helpful. I've got them both set up to run monthly via the User Scripts plugin
December 1, 20196 yr Community Expert Full balance isn't really needed on latest kernels, except if adding new devices and wanting to redistribute data.
