Recommended way to expand capacity

Hi all,

I’m running 900 GB node on Debian 10 minimal server at home with static external IP, with 1 TB HDD for about 2 months, and I have 300 GB left for now.

Can I just add one more HDD to increase capacity?
Or maybe should I replace current HDD with new one with bigger capacity?

Better make separate node, they will share trafik, but if 1 down other is on its own

Did you go for lvm/ext4 install? If so:
pvcreate /dev/sdb1
lvresize …
resize2fs …
restart storage node with new space.
Or :
Create new identity…
Get new auth by email…
Sign tokens…
Open new port on router…
Start second docker process…
Wait 1 month for audit…

First is quicker, second is more resilient

@ andrew2.hart
Do you mean:
option 1: replace HDD with bigger one for the same node
option 2: add another HDD and run another node

i run 15 nodes on windows, works OK

I think you should just add the second disk as more storage to your node BUT I also respect that there is a good and sensible argument for having a separate node for each disk.
At the mo I have both. I have a two disk node that I extended and another that is single larger disk.
Replacing your smaller disk with a larger one is good too. Next you can start a new node with the smaller one and carry on like that. I think this is good and sustainable way to go

Please, avoid using any kind of RAID0 setups - simple LVM without parity, mergefs, JBOD, etc.
With one disk failure the whole node is lost. It will be very unpleasant to have this disaster on month 15


So what I did actually:

There was a lot of data - about 760 GB, so I copied in two steps:

  1. rsync while running node (it takes about 24 hours);
  2. stop node and rsync changes (less than an hour).
