Here's how it works: # 1) Checks for size 0 .nzb files (plex) # 2) Calls diff to figure out if the parity info is out of sync. # 3) If parity info is out of sync, AND the number of deleted or changed files exceed # X (each configurable), it triggers an alert email and stops. (In case of # accidental deletions, you have the opportunity to recover them from # the existing parity info. This also mitigates to a degree encryption malware.) # 4) If partiy info is out of sync, AND the number of deleted or changed files exceed X # AND it has reached/exceeded Y (configurable) number of warnings, force # a sync. (Useful when you get a false alarm above and you can't be bothered # to login and do a manual sync. Note the risk is if its not a false alarm # and you can't access the box before Y number of times the job is run to # fix the issue... Well I hope you have other backups...) # 5) If parity info is out of sync BUT the number of deleted files did NOT # exceed X, it calls sync to update the parity info. # 6) If the parity info is in sync (either because nothing changed or after it # has successfully completed the sync job, it runs the scrub command to # validate the integrity of the data (both the files and the parity info). # Note that each run of the scrub command will validate only a (configurable) # portion of parity info to avoid having a long running job and affecting # the performance of the box. # 7) Once all jobs are completed, it sends an email with the output to user # (if configured). # # # Inspired by Zack Reed (http://zackreed.me/articles/83-updated-snapraid-sync-script) # ####################################################################### find /mnt/volume/media -name '*.nfo' -type f -size 0 -print0 | xargs -0 /bin/rm -f DO_SYNC=0 CHK_FAIL=0 # Expand PATH for smartctl PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin ## USER DEFINED SETTINGS ## # address where the output of the jobs will be emailed to. # comment it out to disable email output EMAIL_ADDRESS="root" # Set the threshold of deleted files to stop the sync job from running. # NOTE that depending on how active your filesystem is being used, a low # number here may result in your parity info being out of sync often and/or # you having to do lots of manual sync.
