Hi I run a now 5TB node. It’s built in a Synology NAS with raid 5. I have 2 options and I’d like your input. I can increase the size of the node (I have the space) or I can create a new volume and run a 2nd node on this new volume. Are there any advantages to any of the options? I remember readi…

Its not recommended to use a large raid5 node because auf the growing i/o. Its better and cheaper to use single drives with no raid. i would suggest anything between 3 and 8 tb per disk.

As you have RAID resiliency you have reduced the chance of your node failing due to a disk error, as such I would increase the allocated space for the node. That is what I’ve done… gradually increased the available space for the one node on my RAID6 array.

With the existing setup and scenario, I agree this is the best solution.

Just increasing the size of the existing node is the easiest, plus you don’t need to wait for a second node to finish vetting. Also I really wouldn’t use RAID5.

Well, I already had the NAS in raid5… Anyway, why not? The thing is, if I had 10 nodes of 5TB and one of them crashed, that would be ok… I would just start another one… But I only have one 5TB node. It took 1.5 years to get there. If the disk would crash, I wouldn’t even start all over again… too…

I see the point of raid5 not being that safe. But my NAS has 6 bays and only 3 are occupied. I can still grow the raid5 and somewhen opt into raid6… I believe raid6 is pretty much safe in terms of disk failure (if you use the right disks, meaning Japanese). Maybe not so much in terms of NAS hardware…

I know that this topic has probably been answered a long time ago, but I would like to comment: I personally recommend having one super node with the best possible redundancy and continuously adding disks / increasing disk capacity. That’s right, if one big node fails, you’ve lost everything, that’…

You mean, you have several disk pairs in raid 1 and combine them all in a large volume? That seems a bit overkill… I believe the typical SNO who hates raids have like 10 nodes in 10 separate disks. Sometimes they loose 1 node to disk failure issues, start another one and still have 9 full throttle.…

2nd node or just increase the 1st node?
