Description

Amahi's WebGUI and other tools such as Gparted reports free space on drives while df claims there is no free space. Its no longer possible to write new files at this point suggesting that the drives are indeed full. Heres some outputs that cpg asked for.

the system default "reserved space" is 5%. it can be changed with

tune2fs -m NUMBER /dev/sdxX

remember that the number is a percentage of reserved blocks though. also, i believe it can be changed while the device is mounted.

$ sudo tune2fs -m 2 /dev/sdf1

              vented from writing to the filesystem.  Normally, the default percentage of reserved blocks is 5%.

one thing we could do is show 5% in a different color or something if it's ext4.

The different color approach is a good idea. Question is how useful is this system-reserved space on the storage drives? 5% off a storage drive is quite a big chunk of space users won’t have access to by default (at least when using greyhole, unsure about normal shares). Would it be possible to have Amahi use a lower % for storage drives by default along with the color difference?
