xfs_freeze

[陈文东]

Hi:

[root at localhost /]# mount /dev/lvm_vg/lvm_lv /nas/
[root at localhost /]# xfs_freeze -f /nas/
[root at 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
