It’s not recommended and can destroy your databases.
And the actual problem is using NTFS on Linux. Do not do that.
Even if you figure out how to revert:
- it will be killed anyway because NTFS is way slower than ext4 on Linux, thus have a higher RAM usage.
- you likely lose your databases due a wrong scheme.
- your ingress likely would be stopped because the software version would be 2 version behind.
I would recommend to convert your NTFS to ext4. Stop the node, backup data, format disk to ext4 and restore data back.
You can also backup your data online: How do I migrate my node to a new device? - Storj Docs, so the downtime would be minimized.
You can do that gradually on the same disk in edge case, but requires a lot more knowledge.
I can describe, how to do, but you may lose data on any point. if you decide to go this dangerous way, I would recommend to do not use GParted for that, use LVM instead. See Moving from Windows to Ubuntu and back
The backup-restore is much more robust method.
