На сервере Centos нет места на диске, но df сообщает, что его много

мой Centos сообщает мне, что у меня не осталось места на диске:

[root@zff isos]# touch test
touch: cannot touch ‘test’: No space left on device

Но df говорит мне, что у меня осталось много места:

[root@zff isos]# df -h

У меня тоже не закончились inodes:

Я не знаю в чем проблема. Любая помощь приветствуется!

ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed.  Mount the filesystem to replay the log, and unmount it before
re-running xfs_ncheck.  If you are unable to mount the filesystem, then use
the xfs_repair -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.
