Today on Linux using vim edit file save times the following error

E514:write error (File system full?)

Looking at the error, the disk is full, so use DF-HL to view the disk usage

$ sudo df-hl
filesystem                         Size  Used avail use% mounted on
/dev/mapper/vg_myserver-lv_root    50G   43G  4.6G  91%/
tmpfs                              7.8G  268K  7.8G   1%/dev/shm
/dev/sda1                          477M   61M  391M  14%/boot
/dev/mapper/vg_myserver-lv_home    1.8T  1.7T     0 100%/home

From the results, it is true that the/home disk is full.

But at this point, when I use the root user to write a file in/home, there is no error.

Checked for a long time, the original is Linux in each partition will retain a part of the root user space, which is dedicated to the root users and their groups to use, other users are not available, the general default is 5% of the total block of data.

This reserved space can be viewed using the following command

$ sudo tune2fs-l <device> | grep Reserved

Like what:

$ sudo tune2fs-l/dev/sda1 | grep Reserved


$ sudo tune2fs-l/dev/mapper/vg_rhserver33-lv_home | grep Reserved

Reserved block Count:23551078
Reserved GDT blocks:      911 Reserved blocks
uid:      0 (user root)
Reserved blocks GID:      0 ( Group Root)

OK, I know the problem, then we clean up the disk space, clean up some disk space, finally I can continue to write data.
