November 3, 2025Nov 3 My number 1 disk is full. First is it okay just to leave it? Second after reading a bit here I changed the minimum free space for each disk in the share setting under my data share settings. I set it to something like 500 GB from 98 GB. The drive as it is shows 28.7 KB and. Did I do the correct thing and if so how do I get the system to start spreading the data out to the other drives? All my shares except for ones that stay on ssd drives are set to use all disks. Any help is greatly appreciated. If there is any info needed please let me know.
November 3, 2025Nov 3 Community Expert I would recommend moving some data to other disks, if there's a filesystem problem, a full disk may complicate things.The floor should be set to twice the file you plan to write to that share, more than that is not needed. Also, check that other shares are not writing to that disk.

Therefore it is impossible for unraid to know where the data is placed on those disks. It only knows you had 2TB drive and somewhere in that entire range of 2TBs you had some data. Therefore it is impossible to restore a range of 2TB onto any smaller of a range.16 minutes ago, JorgeB said:I would recommend moving some data to other disks, if there's a filesystem problem, a full disk may complicate things.The floor should be set to twice the file you plan to write to that share, more than that is not needed.

I had it a 98 GB but somehow the disk is full beyond that. I will double check all shares but if I recall they are set the same at 98 GB minimum space and set to utilize all disks. Any thoughts on what would cause it to fill past the 98 GB. To move the files can I just go to the disk and move it to another manually or would it be better to do that from the share itself but still manually?

This setting does not keep 98GB of unused disk (unless all your new files happen to be larger than 98GB and you never write a file smaller than 99GB to unraid).What happens is if you have a 98GB file, unraid will write that file to the disk leaving you with 0GB of space. Which is exactly what happened and why you now have 28.7kb left on that disk.If having this little bit is not something you desire, typically setting the min-free space to something like 200GB is what you should aim to do in the future. Also I would recommend using the "Unbalanced" plugin to "scatter" some files from your full disk to other disks. Edited November 3, 2025Nov 3 by MowMdown

Which is exactly what happened and why you now have 28.7kb left on that disk. I am moving data from the folder on that disk to another that had over 2.5 TB of space. I am doing that from the disk itself. So should I raise the number of the floor will that make it divert to another disk if the disk has below that number?Sorry for the naive question.
November 3, 2025Nov 3 Community Expert If you're manually moving files from diskA to diskB, the share settings will not take effect.The share settings only apply when using unraid's automated tools such as mover or when writing files to a share via FUSE (/mnt/user/...)
