I have a problem with MergersFs plugin. I'm on testing environment. I have 2 disks (1GB each) in MergerFs union. Minimum free space is set to 500 MB and the LFS "least free space" policy is set. First I copied 450 MB test file to the filesystem and it was there (on the first disk). Next I tried to copy another 450MB file to the filesystem but I'm getting "not enough space error".
My understanding of the LFS policy is that mergerfs is copying files the the disk with least free space till it is full or to the "minimum free space limit" if set. When it hits the limit it should place next file on the second drive, but it doesn't happen.
