<html><head><style type="text/css"><!-- DIV {margin:0px;} --></style></head><body><div style="font-family:times new roman,new york,times,serif;font-size:12pt">havent had much success with testing the hard drives, tried mhdd & seatools with no luck yet.<br>
<br>
Meanwhile i recreated RAID, all shows up OK for now.<br>
<br>
Previously the msgs shown were:<br>
<br>
end_request: I/O error, dev cciss/c0d2, sector 0<br>
end_request: I/O error, dev cciss/c0d2, sector 0<br>
end_request: I/O error, dev cciss/c0d2, sector 1
<br>
<br>
That seems to indicate that the problem is with the disc or array. It
is unable to read the beginning of the device.<br>
So is I do a - dd if=/dev/random of=dev/cciss/c0d2 , that should fail
and therby confirm that the drive or array has issues...do i make any
sense here?<br>
<br>
thanks<br>
