Thread: Some assistance with tune2fs

-

i'm looking assistance tune2fs here. created single 2 tb partition on 2 tb hard drive. when mount anywhere, say, /mnt/media , issue df -h /dev/sdb1 see this:

/dev/sdb1 1.9t 28g 1.8t 2% /mnt/media

realize because ext4 reserves 5% of blocks default.

unmount /dev/sdb1 , issue: tune2fs -m 0 /dev/sdb1 see this:

tune2fs 1.42.2 (9-apr-2012)
setting reserved blocks percentage 0% (0 blocks)

of course, think, success! reboot machine measure, remount drive, , issue df -h /dev/sdb1 again see 28 gb or 2% of drive still filled.

tune2fs -l /dev/sdb1 shows me this:

block count: 488378368
reserved block count: 0
free blocks: 480664949

seems suggest don't have reserved blocks, still being used. empty hard drive have partitioned it.

if issue df -h /dev/sdb1 while unmounted see this:

udev 1.8g 0 1.8g 0% /dev

don't believe matters much.

running du -sh /mnt/media reveals there nothing on drive:
8.0k /mnt/media/

can me figure out what's going on here? why still have 28 gb reserved/used when told not reserve anything. hard drive storage space only. / , /home on drive entirely don't feel need 28 gb reserved.
