bug in /bin/mv !?

[michael]

Hello ,

i think there is a severe bug in the linux "mv" command:

address@hidden:/y/x# mv -v tsm /tsm
`tsm' -> `/tsm/tsm'
`tsm/db' -> `/tsm/tsm/db'
`tsm/db/dbvol01.dsm' -> `/tsm/tsm/db/dbvol01.dsm'
`tsm/db/dbvol02.dsm' -> `/tsm/tsm/db/dbvol02.dsm'
`tsm/db/logvol01.dsm' -> `/tsm/tsm/db/logvol01.dsm'
`tsm/db/logvol02.dsm' -> `/tsm/tsm/db/logvol02.dsm'
`tsm/db/logvol03.dsm' -> `/tsm/tsm/db/logvol03.dsm'
mv: writing `/tsm/tsm/db/logvol03.dsm': No space left on device
`tsm/db/logvol04.dsm' -> `/tsm/tsm/db/logvol04.dsm'
mv: writing `/tsm/tsm/db/logvol04.dsm': No space left on device

Obviously the command /bin/mv did not notice the error given by the
filesystem and proceeded with unlinking the files in the SOURCE !

I consider this as a bug. Could you please check ?

My system is:

Linux roadrunner 2.6.15-28-686 #1 SMP PREEMPT Thu Feb 1 16:14:07 UTC 2007 i686 
GNU/Linux
Ubuntu 6.06LTS

Target and Source Filesystems are both of type xfs. Is this relevant ?
