iSCSI Disk not removable 🙁

 

I created an iSCSI Disk thru the gui and after some tests I cleaned the content and destroyed it from the xenserver. After this, I stopped it in petasan gui and tried to delete it. Since then it is listed as 'detached' and remove actions just result in this loglines in /opt/petasan/log/PetaSAN.log (every 10 seconds):

25/12/2019 23:51:42 ERROR Cannot get image meta object from rbd header.
25/12/2019 23:51:43 ERROR Get ceph image size image-00001 error
25/12/2019 23:51:43 ERROR error opening image image-00001 at snapshot None
Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/PetaSAN/core/ceph/api.py", line 709, in __get_image_size
size = int(math.ceil(float(rbd.Image(ioctx, image).size()) / float(1024 ** 3)))
File "rbd.pyx", line 2755, in rbd.Image.__init__
ImageNotFound: [errno 2] error opening image image-00001 at snapshot None

Any ideas how to resolve this?

Many thanks in advance!

 

We could reproduce this. Note the image does eventually get deleted, the larger the image the longer it takes (each 4M object/sector requires 1 iop ). We will fix the logs + status showing pending delete..we will have an update for this fix.

Thanks for your input.

A general question: We are currently evaluating petasan and will have more questions than usual as a long time user. We plan to have your commercial support in the future, in the case we decide to use petsan in production. We already saw your commercial support offerings on petasan.com, but we are unsure how to do it while evaluating. We know that this is the major time for questions, so we would like to pay for it. Is it possible to buy support for e.g one month or so until we decide the final usage in production? At petasan.com it seems to be only available in terms of 12 month. Could you make an 'special' offer for a limited time? So both side have a good value?

Many thanks in advance!

There is on online update 2.4.1 which fixes the 'detached' status seen during image deletion.
