[SOLVED] Disk usage (free space) discrepancy

I have a strange situtaion regarding disk space utilization in one partition.

The data for the partition is -
Used   : 7.7 GB (1,771 files, 25 subfolders)
Total   : 73.4 GB

but ....
Free   : 57.3 GB (instead of somehing like 65.7 GB)

Some data :
Arch64
The partition is formated with ext4, handles mostly big files and have quite fast turnaround of files on it (there and gone in a day ot two).

Any idea will be helpful.

Ben

Re: [SOLVED] Disk usage (free space) discrepancy

ext4 has the similar rule of reserving 5% of space for super user access as ext2/ext3, see:
http://boncey.org/2006_11_18_reclaiming_ext3_disk_space

Though that doesn't account for all of the "missing" space, I'd guess the journal itself accounts for some.

If you search around the many ext4 threads around here, you'll see that other users have reported the same thing.

Thank you all.

With your help I've found it's an extX thingie and a "tune2fs -m 1 /....." solved the problem (used 1 to be on the safe side).
