Hi All,
I've got a degraded RAID5 which I'm trying to add in the replacement
disk. Trouble is, every time the recovery starts, it flies along at
70MB/s or so. Then after doing about 1%, it starts dropping rapidly,
until eventually a device is marked failed.
When I look in dmesg, I get the following...

I've no idea what to make of these errors. As far as I can work out,
the HD's themselves are fine They are all less than 2 months old.
The box is CentOS 5.1. Linux space.homenet.com 2.6.18-53.1.13.el5 #1

Any suggestions on what I can do to stop this issue?
Steve.
