TrueNas Scale Tips


ENTERPRISE

Recommended Posts

Hello all, 

 

I am still very much a beginner when it comes to TrueNas and it has taken me a while to get to grips with it. However along my journey I have picked up some useful information which I will pop in here. I will continue to add to it as I attain new knowledge! 

 

Moving Datasets

 

You may come across a situation where you would like to move a dataset from one pool to another. In my situation I needed to move a Virtual Machine disk. 

 

To move a file from one storage pool to another, use the following in Shell:

 

Quote

zfs send Apps-VM/VM-HDD/BackupServer-rdkq6a | zfs receive NVMe-Samsung/vm-hdd-backup/BackupServer-rdkq6a

 

Where the red highlighted sections highlighted indicated the file path to the file you wish to move (Pool/Dataset/File), and the blue highlighted indicates the file path you would like to move the file to.
Note the commands in shell are case sensitive, make sure you enter in the file paths exactly as they are.

 

Delete All Pool Snapshots

 

Depending on how many storage pools you have set up Snapshots for, the number of snapshots can quickly build overtime and hurt performance. The threshold at the moment is 10,000 snapshots before you may start to see performance degradation.  TrueNas will generally prune old snapshots automatically depending on the criteria you have set for how long each snapshot should be kept, but if you ever run into trouble there is a quick way to solve the build up.

 

To remove all snapshots for any given storage pool enter the following command in shell:

 

Quote

for snapshot in `zfs list -H -t snapshot -r Tank | cut -f 1` do zfs destroy $snapshot done

 

Where text in red represents the pool name.

 

Error When Upgrading The Plex App 

 

By default, when you install Plex on your TrueNas Scale, it will set the "Advertise IP" to the IP of your TrueNas server. However this has been known to cause issues. If you you have problems upgrading your Plex app, go into the app settings and under "Advertise IP" change the default IP entry, for example 192.168.1.11 and change it to: 

 

Quote

http://192.168.1.11:32400

 

If done correctly, you should have the below.

Useful Utilities

 

-Truetool

 

At the time of writing this, TrueNas Scale is still in its infancy, as such it is missing some functionality. A tool that you can install gives you some extended capabilities for managing your TrueNas Server.  You can read about Truetool and its capabilities here :
