I wanted to add a level of redundancy to our mail server so I purchased the Raidstation3 kit from DPT which includes an external 3 bay drive enclosure and a PCI raid controller. I populated the controller with 64 megs of ram and popped in 3 Ultra2 10,000rpm Seagate Cheetah drives. I built the raid and mounted the two partitions as /var/mail and /var/spool/mail. I now get strange unresponsive timeouts from the machine at random times.. this is what iostat looks like when the machine is unresponsive, sometimes up to 10 seconds at a time. This was not happening before installing this RAID so it leads me to believe that the file system is the problem. tty da0 da1 da2 cpu tin tout KB/t tps MB/s KB/t tps MB/s KB/t tps MB/s us ni sy in id 0 76 0.00 0 0.00 0.00 0 0.00 64.00 1 0.06 5 0 1 15 79 What does the KB/t mean, it seems that it never gets past 64 and when it hits 64 the machine becomes unresponsive. Any suggestions or pointers would be appreciated. Thanks. GVB To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
