@Veklip As /mnt mount point used in the /etc/rear/local.conf file is part of the / file system (and VG /dev/mapper/vg_sys or /dev/sda3) you cannot mount and reformat the same partition. Please use and external disk (e.g. USB devices or NFS mount point) otherwise you will never be able to re-format /dev/sda3.
If on /mnt file system you mounted another NFS file system, then you forgot to tell me.

@gdha Thanks for reminding me.And I mounted another NFS file system onto /mnt in this case. It stranges me that parted command is ok when I recover on another machine.

@Veklip Any further assistance required?

Closing as no questions nor feedback received

According to "no news is good news"
I assume it is (somehow) "fixed/solved/done".
