Re: storage pools ceph (bobtail) auth failure in xenserver SR creation

[John Shen <johnshen64@xxxxxxxxx>]

Hi Dave, Thank you so much for getting back to me.

the command returns the same errors:

[root@xen02 ~]# virsh pool-create ceph.xml
error: Failed to create pool from ceph.xml
error: Invalid secret: virSecretFree

[root@xen02 ~]#

the secret was precreated for the user admin that I use elsewhere with no issues (rbd mount, cephfs etc.), and per the ceph documentation, i just set the secret value with this command

 virsh secret-set-value $(cat uuid) --base64 $(cat client.admin.key)

where the key is obtained from

 ceph auth list

and uuid is generated by

virsh secret-define --file secret.xml

# cat secret.xml
<secret ephemeral='no' private='no'>
        <usage type='ceph'>
                <name>client.admin $(cat client.admin.key)</name>
        </usage>
</secret>

I must confess that I've disabled auth in my test environment. Clearly I should
go back and enable it again :-)

The "xe sr-create" call is handled by "xapi" which calls "xapi-libvirt-storage" which
uses the libvirt API directly to create the pool. It _should_ do the same as running

virsh pool-create ceph.xml

Could you try the "virsh pool-create" and see if that works? If it does, then we need
to figure out what the "virsh" CLI is doing that my Pool.create function call isn't. If
it doesn't then there might be some other missing step. Did you have to pre-create
a secret (is that "virsh secret-create"?)

Cheers,
Dave Scott
