hi!
so, documented in bug-report i have helped by my self. thx for the attention, but another problem came up by this way:

if i try to convert an 2TB volume to an image, cinder crash all the time!

command:
$ openstack image create --volume 3c9414bb-98bd-45d4-9b38-2b073e958f81 --disk-format qcow2 "test - snap - vol - img"

$ tail /var/log/cinder/cinder-volume.log
2019-09-20 14:30:35.202 26339 WARNING oslo.service.loopingcall [req-4435ac18-f021-4784-8fcd-b73d257636a7 - - - - -] Function 'cinder.service.Service.report_state' run outlasted interval by 2.95 sec

in the same way, the complete controller will unavailable and openstack will switch to the other one and bring it to active ... this is not so good :( i realy need this volume/image ...

greez & thx, volker...

Hi Volker:

Would you like running command ‘collect’ in system to collect all necessary logs ?

And then create new bug https://bugs.launchpad.net/starlingx and attached log to bug.

Thanks.

Austin Sun.

Volker,

You still have 1.0 running (2+2+3) and you still have your data, right? You just want to backup your user data & restore it in your new 2.0 deployment? I am hoping that you didn’t lost your data.

Thx. - cindy

hi,

i'm big in trouble... i'm with you from the first hour and run an staringX 2018.10 in production mode (i know, i know, no comment please ;)) so, update to the new starlingX 2.0 version will need to reinstall the complete stack, but i need to backup some VMs first.

based on this dokumentation https://docs.openstack.org/nova/rocky/admin/migrate-instance-with-snapshot.html i got always an zero byte image, at the internet i got some posting that indicate the same problem, but for now, i cant fix it :(

i have an full starlinX install with dedicated storage (2x controller, 2x compute, 3x storage). maybe someone can help me?

greez & thx, volker...
