RAID 5 and 6 were found to be losing data without a drive going bad. I pulled all my data off to backup and restored it on a freshly built array under XFS. That's not something I enjoy doing too often.
- rodgerd 9y agoYeah, having scrubs corrupt good data is basically the worst-case scenario for an FS whose selling point is checksumming for data integrity. I ran btrfs for several years, and while the features are great (per-subvolume RAID policies, lightweight snapshots, unRAID-style RAID), I got sick of testing my backups regularly. I wouldn't be surprised if that's not uncommon.
