Re: Remove volume

Hi,

use rbd children to see dependencies 

rbd children <image>@<snapname> for example

Hi Jean,

 

Thanks a lot.

 

I have  the following images in ‘ images’ pool:

--------

 

root@compute:/home/oss# rbd -p images ls

0c605116-0634-4aed-9b3f-12d9483cd38a

9f1a5bdc-3450-4934-99b3-d1b834ad9592

b16aac0e-621f-4f36-a027-39c86d28011f

 

When I try deleting them I get this error:

----------

root@compute:/home/oss# rbd -p images rm 0c605116-0634-4aed-9b3f-12d9483cd38a

2014-03-13 04:28:19.455049 7f751275e780 -1 librbd: image has snapshots - not removing

Removing image: 0% complete...failed.

rbd: image has snapshots - these must be deleted with 'rbd snap purge' before the image can be removed.

 

When I try deleting the snaps , I face the following error:

--------

root@compute:/home/oss# rbd -p images snap purge 0c605116-0634-4aed-9b3f-12d9483cd38a

Removing all snapshots: 0% complete...failed.

rbd: removing snaps failed: (16) Device or resource busy

2014-03-13 04:31:39.512199 7f1ac4134780 -1 librbd: removing snapshot from header failed: (16) Device or resource busy

 

 

How to delete the images ?

 

 

Thanks

Kumar

Hi

 

rbd -p <poolname> rm <imagename>

 

e.g. rbd -p volumes rm volume-55abf0d4-01a7-41d0-9e7e-407ad0db213c
