Incorrect free space displayed after filesystem resize

A few days ago I resized the fileystem from 16 GB to 26GB using GParted as the system already had consumed 15GB of the total. The file system was expanded using GParted and there wasn't error and the process finished successfully.

Today I got a "low on disk space" kind of message. When I checked available free space of the filesystem it says 25GB of 26GB used. When I scanned the filesystem using gdmap and filelight, they still show that I have only used 15.4 GB.

I issued df -h and it showed I have used 25GB of 26GB but du -sh gives 4.1G

At the moment I am not sure what is causing this and how can I fix it. Any help would be appreciated.

Thank you.

Re: Incorrect free space displayed after filesystem resize

Please post the actual command output rather than describing it.

See https://bbs.archlinux.org/viewtopic.php?id=57855

Which filesystem are you using?

Also post the output of:

df -i
# parted -l

df -h gave me:

dev             1.9G     0  1.9G   0% /dev
run             2.0G  808K  2.0G   1% /run
/dev/sda8        25G   24G  498M  98% /
tmpfs           2.0G  3.9M  2.0G   1% /dev/shm
tmpfs           2.0G     0  2.0G   0% /sys/fs/cgroup
tmpfs           2.0G   14M  2.0G   1% /tmp
tmpfs           393M   12K  393M   1% /run/user/1000

du -sh gives:

4.1G	.

I am using ext4 filesystem and df -i gives :

Filesystem      Inodes  IUsed   IFree IUse% Mounted on
dev             493463    365  493098    1% /dev
run             502369    452  501917    1% /run
/dev/sda8      1656480 530501 1125979   33% /
tmpfs           502369      7  502362    1% /dev/shm
tmpfs           502369     12  502357    1% /sys/fs/cgroup
tmpfs           502369     44  502325    1% /tmp
tmpfs           502369     24  502345    1% /run/user/1000

and parted -l for the filesystem is:

Number  Start   End     Size    Type      File system  Flags
...

 8      60.5GB  87.7GB  27.2GB  logical   ext4
...

Re: Incorrect free space displayed after filesystem resize

What does "ncdu -x /" show?

Re: Incorrect free space displayed after filesystem resize

Boot from a live medium, mount /dev/sda8 somewhere and see what df/du/ncdu show about it.

Re: Incorrect free space displayed after filesystem resize

A few days ago I resized the fileystem from 16 GB to 26GB using GParted

Sanity check - did you use a live disk (i.e. gparted live) to resize? Is it possible that the filesystem was still mounted when you resized?

I used a live CD to resize the partition and I am fairly sure that I didn't have the filesystem mounted at that time, even if it were, gparted wouldn't work until I unmount it.

Re: Incorrect free space displayed after filesystem resize

Have you run fsck on that filesystem?

Re: Incorrect free space displayed after filesystem resize

Did you try deleting the partition (after backing up important data) and resize it with cfdisk?
