Hi,

I am trying to rename in the same pool.

sudo rbd rename rbdPool1 -p testPool2 rbdPoolTest1 -p testPool2

-Thanks & Regards,

Hi.

You can only rename in the same pool.

For transfer to another pool: rbd cp and rbd export/import.

Hi all,

Whether renaming rbd is allowed?

I am getting this error,

ems@rack6-ramp-4:~$ sudo rbd rename rbdPool1 -p testPool2 rbdPoolTest1 -p testPool2

rbd: mv/rename across pools not supported

source pool: testPool2 dest pool: rbd

ems@rack6-ramp-4:~$

ems@rack6-ramp-4:~$ sudo rbd rename rbdPool1 rbdPoolTest1

rbd: rename error: (2) No such file or directory

2014-12-03 18:41:50.786397 7f73b4f75840 -1 librbd: error finding source object: (2) No such file or directory

ems@rack6-ramp-4:~$

ems@rack6-ramp-4:~$ sudo rbd ls -p testPool2

rbdPool1

ems@rack6-ramp-4:~$

Why its taking rbd as destination pool, though I have provided another pool as per syntax.

Syntax in rbd help:

rbd   (mv | rename) <src> <dest>                  rename src image to dest

The rbd which I am trying to rename is mounted and IO is running on it.

-Thanks & regards,
