Hi,
beginning from the start-post if have a question:
How did you use your box? 24/7? Powering down the box anyway?
The errors are not raid related - only FS related. And this seems that you (sometimes?) hard cut the power off your system, or something similar.
Hint:
fsck needs often more runs ...
And what is the recommendation for the 3X3TB drives I have? I need at least 6 GB for storage.
- Backup, Backup and Backup ... then the redundancy is optional
- RAID5 (even it is "only 4 business contiuity" ... it makes this job)
- ZFS-Z1 (more complex than RAID, but also more powerful - very RAM aggressive)
- SnapRAID
- single disks (or LVM) with rsync-construct
- UPS (USV in german)
