Store Bitcoin Core data (blockchain) on a different harddrive

StartOS Support
1

Hello everybody,

i just start with startOs on a VM, i want to install bitcoincore on a separate drive /dev/sdb1. So i mount it manualy there /mnt/bc but when i change /etc/fstab to mount it permanently the /etc/fstab keep deleting the mount that i previously do. Any idea what is causing the cleaning of /etc/fstab ?

For the next part i will follow this tuto:

Thanks everybody!

There’s no supported way to point different services to different drives. All data goes on one partition or drive, and the OS goes on another partition or drive.

Since StartOS is immutable and changes you make outside the standard options in the GUI do not persist across reboots, you’ll have to search this forum to see how you’d use

/usr/lib/startos/scripts/chroot-and-upgrade

to persist changes, and use fstab.

BUT.

There seems to be an obvious solution here that you might be missing. If this instance of StartOS in the VM is going to be used for just Bitcoin, why not use the VM to point the entirety of the data drive/partition to another physical drive? That’s already default behavior and just a question of tweaking the VM settings.

Thanks StuPleb for the answer.
i wanted to split the data on HDD and the os on nvme but too tricky for just a few second win at reboot ^^.
I just put the all the vm on the HDD, gona replicate it, will be enough.
I am impress how StartOS seems way more stable on hyperV than Umbrel, i had so much trouble on UmbrelOS with the virtualization.
Can’t wait to find out all the details how startOS works.
