User defined minimum allowed free space

Not only the minimum. You should specify the allocated space also, but if you would want to overallocate, see my other thread… (link down), you will need also to specify a good minimum.

In my case, running Synologys and Ubuntu servers, I can only use that trick on Ubuntu, because the OS has it’s own NVMe drive.
But Synology copies the DSM (it’s OS) on all installed drives; this way in case of failure of one drive, the machine continues working like nothing happened.
