Hi,
By chance I found this statement in the Linux RAID Wiki:
"Do NOT use [USB devices] as part of your array. They have
a timeout/disconnect mechanism which interacts very
badly with the raid code." [0]
Could someone elaborate further on this? Does "interacts very
badly" mean that there will be potential data loss / data
corruption? Or does "very badly" just mean short, temporary
performance issues / lags upon a disk failure?
Regards, Linus
