- etskinner 8y agoThey just don't use Raid 5/6
- rleigh 8y agoThat's by far from the only failure case to worry about. In addition to random dataloss, the most frequent failure cause I dealt with was complete unbalancing making the filesystem read-only. This happened every ~48 hours of continuous use! I've not read that this is fixed yet, but I haven't used it in the recent past due to this making it unsuitable for production use.
