Bob2 Posted July 29, 2021 Share Posted July 29, 2021 I'm hoping unRAID has this by default (or a checkbox) so that I can avoid buying a synology as they're looking pricey & I already have a spare i7 computer and a load of old drives I'd love to set up as a NAS! I found this interesting article online about silent bitrot: https://louwrentius.com/scrub-your-nas-hard-drives-regularly-if-you-care-about-your-data.html It's an outdated article though, so I'm wondering if unRAID devs have now released an update to include regular BTRFS scrubbing? Thanks Quote Link to comment
Turnspit Posted July 29, 2021 Share Posted July 29, 2021 Ypu, scrubbing is possible. And with a little script, it should be possible to be automated. Quote Link to comment

Thanks As stated, you can run a simple script via User Scripts to detect bit-rot on BTRFS devices (in the array it can detect it but not fix them automatically). The cache pools can be fixed. But, your article isn't exactly a fair comparison. A URE in a traditional RAID environment (synology) is catastrophic, because if you exceed your redundancy you've lost every single file. Worst case with Unraid is you will only ever lose a portion (probably a single file corrupted) if a URE happens and you've exceeded your redundancy. Quote Link to comment
