Package: bugs.debian.org Severity: minor X-Debbugs-Cc: [email protected] Filesystem scrubbing gets initiated by a number of different mechanisms. We have /etc/cron.d/e2scrub_all as well as systemd's xfs_scrub_all.timer and e2scrub_all.timer. Not only for a newbie it gets difficult to understand what mechanism in particular initiated the scrubbing which seems to be considered a necessary and benevolent task like it was in the last century doing defragmenting FAT filesystems.
Problems in general: 1. Scrubbing is still considered experimental and therefore risky with some filesystems. (See kernel comments and log entries.) 2. In some environments, scrubbing would be considered outright destructive (when working on forensic media, e.g.) 3. It keeps I/O busy for no reason which is unwanted in business environments. Conclusion: The whole scrubbing scheduling by default should be abolished.
