LUCreateInstance: implement disk adoption mode

This new mode, valid only for the plain template disk, allows creation
of an instance based on existing logical volumes (preserving data),
rather than creation of new volumes and OS creation.

The new mode works as follows:...

ConfigWriter: add an LV reservation manager

This patch adds an LV reservation manager to be used for LV names. Since
we now have four such managers, we create a list for easier release.

Implement replacing cluster certs and keys via “gnt-cluster renew-crypto”

Recent changes to “gnt-cluster verify” made it complain on expiring SSL
certificates. While it was possible to replace the SSL certificates and
other cluster secrets manually before, doing so was cumbersome. Cluster...

cli: Add helper function to stop and start whole cluster

Replacing cluster certificates and keys requires all cluster daemons to be
shut down. This might also be handy for the cluster merger tool, though
the function might need a few more extensions.

bootstrap: Add new function to create cluster certs and keys

The code to generate cluster certificates, keys and secrets is currently
spread over several places. It makes sense to move it to a separate
function as we want to provide the user with the ability to automatically...

utils.CreateBackup: Use human-readable instead of seconds since Epoch

Seconds since the Epoch are not easily readable by a human. Using a
formatted timestamp makes it easier (e.g.
“….backup-2010-03-12_14_02_43.…”). This patch also makes OS logfiles use
this formatted timestamp....

Verify cluster certificates in LUVerifyCluster

When using pyOpenSSL 0.7 or above, LUClusterVerify will start to show a
warning 30 days before a certificate expires. 7 days before the
certificate expires, the warning becomes an error. Once expired,
LUVerifyCluster will always report an error. The latter is also supported...

utils: Add function to extract X509 cert validity

X509 uses ASN1 GENERALIZEDTIME or UTCTIME to store certificate validity.
pyOpenSSL 0.7 and above allow us to retrieve both “notBefore” and
“notAfter” as strings. Parsing them turned out to be a challenge since...
