Hi guys,
I have a little storage box. It has an IDE with the OS on (Debian
Lenny) and four SATA discs in a software RAID5. Every now and then,
one disc (sdb) fails. The first time it happened, I replaced it, but
the replacement does the same. When this happens, I fail it, remove it,
add it, it rebuilds, and run absolutely fine for several more month.
The second line from the log is what I'm wondering about. Is this
simply a faulty cable or is there more to this?
