Hi,
I've now heard that this problem, of Cloudstack being messed up after
interruption of the NFS shared storage access, is well known. Does anyone
have a fix or work-around?
Kirk, thanks for your help so far.
Both the master and the host servers can mount both primary and secondary
stores, and read and write them. No permissions nor IP access seem broken.
I also checked the log levels on the hosts, and both FILE and com.cloud
were already set to DEBUG. I tried setting them to TRACE, but got no
additional useful info.
On the host, I tried just restarting the cloudstack-agent service. In the
resulting logs, the following snippet occurs. The best interpretation I
can make of it is that "no storage vol with matching
name 'f23a16e7-b628-429e-83e1-698935588465'' is the key issue, and that
should relate to secondary storage, where the templates are stored. But
this uuid doesn't seem to be related to the actual secondary storage pool,
whose uuid is b7fd7b11-c0f7-4717-8343-ff6fb9bff860. The primary storage
pool is uuid 9c6fd9a3-43e5-389a-9594-faecf178b4b9, and it seems to be
properly automatically mounted on all hosts and the master.
** It concerns me that the secondary storage pool does NOT seem to be
automatically mounted. Is it supposed to be? If not, how are the hosts
supposed to find the templates, before a System Router VM can even be set
up?
Below is the relevant host agent.log snippet, and also a dump of the
storage_pool table from mysql.
Thanks in advance for any suggestions.
