I have a 2TB SSD without OS on it, only data, it is on /dev/sda1. It is full but I have about 100GB that I cannot used on it. I have already extended at maximum with GParted.

df|grep /dev/sda1 returns :

/dev/sda1 1921802432 1824110376 0 100% /mnt/b85107de-9722-4bf5-8e9a-c810fbfb7e76

here is GParted

here is the disk analyser

How to retrieve the unused space ?

Thanks beforehand.

  • The unuse space seems to be in the partition. The only way to use it, is to fill with more data(not best idea) or to shrink partition and make new partition. Partition must be unmounted before you can work on it. 100GBs left on 2TBs drive will read as full(<than 1%). Would leave drive as is, since it probably keeps some GBs free for maintenance and get another drive. – crip659 Dec 07 '20 at 22:21
  • the command sudo tune2fs -m 2 /dev/sda1 solved the problem, it reduced the reserved storage. Maybe 5% is quite high. Thanks a lot – YesWeStillCan Dec 07 '20 at 23:57
