Troubleshooting Boosting the Performance of NFS Transfers A • When the NSS powers up, an SNMP trap sends a notification. • When the Administrator first logs into the configuration pages following the shutdown, a message appears. • An email is sent to the defined email address if the Administrator is set up to receive an email for power loss. . Following an unclean shutdown of the NSS: STEP 1 Do one of the following: • Review/Edit the System Settings Manually: Go through each setting, including the time setting to make sure that nothing has been negatively altered. If you make changes to the settings, we highly recommend that you take a USB backup. • Back up the System Settings from a USB Backup: If you have a valid backup on a USB flash device, it might be easier to restore the system settings from the backup (versus manually going through and checking each system setting). STEP 2 If you attempt either of the above unsuccessfully, restore the configuration settings back to the factory defaults, and then either restore the configuration settings from a USB flash device backup or manually edit the settings. NOTE The factory default administrator password is "admin". Boosting the Performance of NFS Transfers You can substantially improve the NFS performance by increasing the size of read and write buffers on the client. These buffers are sized at 4 KB by default but can be changed at mount time. For example: mount -v -t nfs 192.168.1.1:/mnt/RAIDA/vol1/share1 /mnt/client -o nfsvers=3,rsize=32768,wsize=32768 where: • 192.168.1.1 is the IP address of the NSS system • /mnt/RAIDA/vol1/share1 is the path to the share Linksys Small Business NSS4000 and NSS6000 Series Network Storage System Administration Guide 166
