Services that run on a Synology are constantly being updated. Software updates for the binaries and other artifacts can quickly and easily be updated. To do so, open the Synology web interface and then open Package Center. From Package Center, click Update for each or Update All to upgrade all services at once, as seen below.You will then be prompted to verify that you want to run the update. Any services that are being updated will restart and so end users might find those services unresponsive or have to log back in after the service comes back online.

Data Domain
Data Domain appears to be the next casualty of the swift consolidation of IT vendors. NetApp and EMC continue in what has become a bidding war in the acquisition of Data Domain. NetApp began the bidding at $1.5 Billion and it has slowly eked its way up to $1.9 Billion. What are they buying? Something they both already claim to have a really good solution for, data de-duplication. While this acquisition is not as big of a deal as other recent buyouts it is worth noting. NetApp and EMC are becoming bitter rivals and the technology and research and development that each is looking to acquire via Data Domain would…

Finding Disk Speeds on a NetApp
On a NetApp you can determine the disk speeds for drives in your Filer using the following command: storage show disk –a This will show all of the disks. Each disk has a unique identifier within the NetApp, indicated by a numeric sequence typically starting with a 2a, 2b, 3a, 3b, etc. You can obtain detailed information about each disk by showing disk with the unique identifier in the command. You can also see a listing of disks by volume using the following command (they will appear in the RPM column): vol status -r This will show a variety of statistics, including the disk type, speed, etc. The vol command…

NetApp Failovers
Each controller of a NetApp FAS will typically have two network interfaces. Provided I have two storage controllers (and I usually do) I typically prefer to setup a NetApp in an automated failover scenario. A NetApp active/active configuration consists of two storage nodes) whose controllers are connected to each other either directly or through switches. The nodes are connected through a cluster adapter or an NVRAM adapter, which allows one node to serve data to the disks of its failed partner node. Each node continually monitors its partner, mirroring the data for each other’s nonvolatile RAM (NVRAM). Before configuring the filers for an active/active clustered failover, first verify that the…

The NetApp Halt Command
When shutting down a NetApp Filer, you should use the halt command. The halt command flushes file system updates (eg – flushing memory to disk) out to disks and clears NVRAM, which helps to make sure the system comes back online properly and no data is lost during the process (’cause you know, data loss is kinda’ bad on your storage devices, right). Flags that can be used with the halt command include -d, -t and -f, which sets a dump string (dirty shut down, only use this if a standard shutdown doesn’t work), an interval for the shutdown to occur (in minutes) and prevents other node from taking over…
