I really appreciate you help  Eric.

Yes It is. /mnt/celerra is a NFS mountpoint:

pcocol01:~ # mount | grep celerra
212.145.146.8:/FS_AUX/FS_AUX on /mnt/celerra type nfs 
(rw,addr=212.145.146.8)

But, honestly I think It's not a real I/O problem. I can move other 
mailboxes from one partition to another without problem.

[...]
pcocol01:~ # cyradm -u cyrus -pass XXXXXXX localhost
localhost> cm user.movingproblem default
localhost> exit
pcocol01:~ # ls /buzonesdir/user/movingproblem/
cyrus.cache  cyrus.header  cyrus.index
pcocol01:~ # cyradm -u cyrus -pass XXXXXXXX localhost
localhost> renm user.movingproblem user.movingproblem part3
localhost> exit
pcocol01:~ # ls /mnt/celerra/user/movingproblem/
cyrus.cache  cyrus.header  cyrus.index
[...]

Also I don't see any NFS error or warning in log files.

?????????

Thank you again.
