Hi:

 

[root@localhost /]# mount /dev/lvm_vg/lvm_lv /nas/

[root@localhost /]# xfs_freeze -f /nas/

[root@localhost /]# lvcreate  -s -L 40M -n cwd  /dev/lvm_vg/lvm_lv

  Rounding up size to full physical extent 48.00 MiB

  device-mapper: suspend ioctl on  failed: Device or resource busy

  Unable to suspend lvm_vg-lvm_lv (253:0)

  Failed to suspend origin lvm_lv

  libdevmapper exiting with 2 device(s) still suspended.

 

 

 

 

Why?

 

Thanks
