Subject: Re: md raid 5 with xfs copying data through Samba

Michael,

It does the same thing that happens when I cd to the mount point. The
Putty terminal stops responding (not Windows style, just no output,
etc.)

I am running the PROMISE SATA300 TX4 PCI SATA II 4:
http://www.newegg.com/product/product.asp?item=N82E16816102065

Before I was running the Rosewill Rc-209:
http://www.newegg.com/Product/Product.asp?Item=N82E16816132006

I had the same problems with both cards. For the hard drives I'm using
four Seagate Barracuda 7200.10 ST3250820AS 250GB drives. I have an AMD
Athlon 2800+ with 1 GB of ram on a nforce 2 chipset.
