I got this message in GParted when seeing information about a partition that is marked with the yellow warning icon in the partition list:
e2label: No such file or directory while trying to open /dev/sda6 Couldn't find valid filesystem superblock. Couldn't find valid filesystem superblock. dumpe2fs 1.42 (29-Nov-2011) dumpe2fs: No such file or directory while trying to open / dev/sda6 Unable to read the contents of this file system! Because of this some operations may be unavailable. The cause might be a missing software package. The following list of software packages is required for ext4 file system support: e2fsprogs v1.41+.
I've checked that e2fsprogs is already the newest version. This is the result of
/dev/sda /dev/sda2 /dev/sda5 /dev/sda7
There's no /dev/sda6, but this is the result of
sudo fdisk -l:

How to address this problem? Please tell me if my information is not enough. I don't know exactly what information is related to or needed to solve this problem. Leak of knowledge about this problem also makes me difficult to google it.
It seems this problem appeared after I tried to make 2 new ntfs partitions when another partition is in use (i.e. current Ubuntu partition). I reproduced the scenario and got this message when creating one of them:
GParted 0.11.0 --enable-libparted-dmraid Libparted 2.3 Format /dev/sda4 as ntfs 00:00:02 ( ERROR ) calibrate /dev/sda4 00:00:00 ( SUCCESS ) path: /dev/sda4 start: 52,854,784 end: 61,239,295 size: 8,384,512 (4.00 GiB) set partition type on /dev/sda4 00:00:02 ( ERROR ) libparted messages ( INFO ) Error informing the kernel about modifications to partition /dev/sda3 -- Device or resource busy. This means Linux won't know about any changes you made to /dev/sda3 until you reboot -- so you shouldn't mount it or use it in any way before rebooting. Failed to add partition 3 (Device or resource busy)
I've rebooted, but there was no change.
