Sheepdog storage image migration/creation bug

[Toshik]

Hello!

I have encountered strange bug in storage migration system (or gui?)

I have VM with two HDD:
vm-500-disk-1
vm-500-disk-2

I have migrated "vm-500-disk-1" to sheepdog storage, now I click on "vm-500-disk-2" and start migration.
Here is error:

[COLOR=#000000][FONT=tahoma]create full clone of drive virtio1 (local:500/vm-500-disk-2.raw)[/FONT][/COLOR]
[COLOR=#000000][FONT=tahoma]TASK ERROR: storage migration failed: sheepdog create vm-500-disk-1' error: Failed to create VDI vm-500-disk-1: VDI exists already[/FONT][/COLOR]

It seems that Proxmox trying to migrate wrong image

Update:

Also I can't create second HDD on sheepdog storage:

sheepdog create vm-112-disk-1' error: Failed to create VDI vm-112-disk-1: VDI exists already (500)

Here I add "vm-112-disk-2", but Proxmox tries to add "vm-112-disk-1"

Re: Live storage migration bug

Did you refresh your hardware tab before trying another storage migration?

Re: Live storage migration bug

Yes, I have refreshed it. Tried other VMs with 2 HDD configuration - same error
Tried other cluster nodes - same error

Re: Live storage migration bug

Is there any way to "hotfix" this behavior?

Hi,

I can't reproduce it here, it's working fine.
(sheepdog 0.6 - last pve).

Can you post the result of "collie vdi list" command ?

Re: Live storage migration bug

I can confirm this problem, pve 3.0, sheep 0.6.

The bug is when the storagename is != 'sheepdog'.
Patch are sent to the mailing, if you can't wait, try to rename your storage as 'sheepdog' as workaround.
