Lustre discuss - Dec 2009 - Lustre deactivated ost error verry strange.

i am getting a strange error 
Dec 28 09:50:06 nas-0-1 kernel: LustreError: 137-5: UUID
''work-OST0000_UUID'' is not available  for connect (no target)
Dec 28 09:50:06 nas-0-1 kernel: LustreError: Skipped 3169 previous similar

when i investigate the /proc/fs/lustre directory i find that there is no
work-OST0000 device
there is only a work-OST0001device 
i have deactivated the work-OST0000 device in lctl but is there a way to delete
an ost the documentation is not that clear
root at nas-0-1 lustre]# cd obdfilter/
[root at nas-0-1 obdfilter]# ls
home-OST0002  home-OST0003  num_refs  scratch-OST0002  scratch-OST0003 
work-OST0001  work-OST0002  work-OST0007  work-OST0008
[root at nas-0-1 obdfilter]# 

i have been googling for a way to delete the OST but i cant seem to find one.
