Hello to all.
First sorry my terrible english.
Some time ago we buy a new server on which we have installed SL-45.
The server has the following characteristics:
Super Micro motherboard
2 cpus dualcore Intel Xeon 2GHz
4GB of ram, 250GB of disc.
On that occasion the server had a LSI SATA RAID controller, with the
raid with two disks of 250GB. For some reason that we do not know that
until today, the disc access was very slow, at the point of the machine
go getting increasingly slow until freeze. This happened in a short
time, a matter of minutes after start the nfs server. The only thing I
could find is that, looking at the top, we getting all processors
increased the wa nearly 100% with us less than 10% in all processors. We
remove the raid controller and made the raid via software and the
problem had apparently disappeared. Today, doing some searches through
files, commands such as du and find took too long, turning the wa to
stay near 80% in almost all processors, with the difference that when I
concluded the program, the system returned to normal.
Please send me any suggestion that I continue to research.
Thank you now.
