problem with NAS

[Fernando André <andrefernando@tvtel.pt>]

Hello, I'm having a problem with writing to a nfs share(not nfs4), have 
2 mail servers writing to it, but one of them is taking to long to 
deliver the email locally the other delivers it fine. Think it might be 
related to input to the disks storage but can't determine the exact 
cause, any tips ?

I'm testing the NAS it has a LSI card

02:0e.0 RAID bus controller: LSI Logic / Symbios Logic Unknown device 0411

RAID 3Ware mod. 9650se-24ML

have  a  Intel(R) Xeon(R) CPU            5110  @ 1.60GHz , 1GB Ram ddr2
a 1Gbps switch where the 3 machines are connected

The tests were made by replicating emails to the local machine into 
Maildir format users accounts.

Disks on the NAS are SATAII

Thank you in advance,
Fernando André
