[Users] Bug: adding LocalStorage Data Centers

Thu Oct 10 10:14:54 EDT 2013

I'm sorry, I misread the connections for the storage domains..

this is the output of the storageconnections:

<storage_connections><storage
href="/api/storageconnections/b3eca2aa-5983-404f-af06-c7ca10b9fa23"
id="b3eca2aa-5983-404f-af06-c7ca10b9fa23"><type>localfs</type><path>/home/DATA</path></storage><storage
href="/api/storageconnections/87dc99f6-98fe-4828-99da-f228958748c0"
id="87dc99f6-98fe-4828-99da-f228958748c0"><type>localfs</type><path>/data/images/rhev</path></storage><storage
href="/api/storageconnections/84970346-ae22-49cf-8a4c-c1bd27a0b7a4"
id="84970346-ae22-49cf-8a4c-c1bd27a0b7a4"><address>managementserver32</address><type>nfs</type><path>/var/lib/exports/export</path></storage><storage
href="/api/storageconnections/1179a3b3-8f18-4696-bda8-094b7a2f5c35"
id="1179a3b3-8f18-4696-bda8-094b7a2f5c35"><address>managementserver32</address><type>nfs</type><path>/var/lib/exports/iso</path></storage></storage_connections>

So this is one export domain, one iso domain and 2 localfs storage
domains, I suppose our two working ones. So no sign of this 5th
supposed connection?

the fun part: the export domain does not show up any more in the
mangement, so I tried to delete the connection via curl:

curl -X DELETE -H "Accept: application/xml" -u user:password
https://192.168.150.50/api/storageconnections/84970346-ae22-49cf-8a4c-c1bd27a0b7a4
--insecure

and got as response:

so this method does not seem to be allowed?
