Hi-- I've had the following problems... we're currently running with 3x18 GB 10k Segate drives and an Asus p2b-ds <http://www.asus.com/products/motherboard/pentiumpro/p2b-ds/spec.html>; with onboard scsi card. The drives are divided into 3 partitions /usr /var / and a RAID 5 of 26 GB. I was able to recover by just doing vinum start on the stale drive, but it brought the system down, and i need to make sure this doesn't happen again. Does anyone have any suggestions? Is this a CAM or vinum problem? or should I look to hardware. Here's the standard list. What problems are you having? Using lftp, I was in the midst of ftping a 50 MB or so file to the raid directly. After about 5% was done, the entire box froze. As it is remote, I don't know if the drives were accessing, but all open ssh sessions just stopped, i could ping and nmap the box, but when I tried to initiate an ssh, they would just open, and sit there. I've previously been able to copy a couple of hundred MB back and forth, with seemingly no problems. That was a few days ago. Which version of FreeBSD are you running? > uname -r 3.4-STABLE Have you made any changes to the system sources, including Vinum? No, everything is unchanged.
