Split data on 2 HDDs

Node Operators
1

Good evening everyone,

I wanted to ask a particular question.
I have a 12TB node on a single external HDD, with 11TB of STORJ data.

is it possible to split data from 1 single 12TB HDD into 2 different 6TB HDDs?

Best regards

Hi,
You can merge the 2 hdd into one big virtual disk (raid0) then move data to it, data will be stripped across 2 disk
But it’s not recommended, if one disk dies node will die.

You cannot run more than one drive on a single node. Like Dali44 mentioned, you can string drives together via RAID, but if you want to use more than one drive, you would need to run another node.

And you can’t take half the data off the one node and move it to another node. The data is tied to the identity of the node itself, and you can’t run two nodes with the same identity.

Thanks for your answers.
So isn’t there a way to do a data migration from one node to another?
And if I have to shrink my hdd with a smaller one how should I do?

You could reduce space in your config to under 6TB.
Then move the data to a new HDD and start a second node one the other 6TB HDD.
BUt splitting is not possible, only with Raid 0 but that comes with a risk of one disk failure you lose all data.

Data belongs to a node so you cannot move just it and fill other node. All you can do is move whole node to different device.

And as @pixxel wrote, you can reduce space in config, wait for the deletions to bring it down below that threshold, and then move node to 6 TB disk. Though I don’t know how fast it’s going to be brought to the desired level. If you really need to free up this 12 TB drive “now”, then all you can do is go RAID0/JBOD/LVM, but know the risks.
