14 years agoA rewrite of LUClusterVerify
Iustin Pop [Thu, 18 Mar 2010 10:33:42 +0000 (11:33 +0100)]
A rewrite of LUClusterVerify

Per issue 90, current cluster verify is very very brittle. It's one of
the oldest pieces of code, with only additions without cleanups over the
last years.

Among its problems:

- data initialization interspersed with verification of RPC results,
  leading to non-initialized data for some branches
- due to the above, we order strictly some checks and we have the case
  where a bad node time result will skip checking of node volumes
- many many local variables, with each new check adding a new dict,
  leading to a spaghetti of dicts in the main Exec function
- monolithic code, both Exec() and _NodeVerify() do a lot of
  independent checks

This patch does an imperfect rewrite, but at least we gain:

- a clear infrastructure for adding more checks (the new NodeImage
  class, with it's clear and documented fields), and removal of most
  per-node dicts from the Exec() function
- the new NodeImage object should allow better type safety, e.g. by
  allowing pylint to check the actual object attributes rather than
  strings as dict keys
- a-priori initialization of data fields, eliminating the need to
  introduce dependencies between checks
- per-result-key status field, allowing elimination of duplicate error
  messages (where we want)
- split of most independent checks into separate functions, for greater
  clarity

The new code, being new will probably introduce for the short term more
bugs than it removes. However, it should offer a much better way for
extending cluster verify in the future.

Implement conversion from plain to drbd

This patch adds a new mode to instance modify, the changing of the disk
template. For now only plain to drbd conversion is supported, and the
new secondary node must be specified manually (no iallocator support).

The procedure for conversion works as follows:

- a completely new disk template is created, matching the count, size
  and mode of the instance's current disks
- we create manually (not via _CreateDisks) all the missing volumes
- we rename on the primary the LVs to the new name
- we create manually the DRBD devices

Failures during the creation of volumes will leave orphan volumes.
Failure during the rename might leave some disks renamed and some not,
leading to an inconsistent instance.

Once the disks are renamed, we update the instance information and wait
for resync. Any failures of the DRBD sync must be manually handled (like
a normal failure, e.g. by running replace-disks, etc.).

Switch burnin to cli.JobExecutor

Burnin has a custom job executor, because of its need to retry some job
series.

While we cannot replace all of it, at least the execution we can switch
to cli.JobExecutor, to take advantage of the recently-introduced
out-of-order waiting.

Add a partition function to split a list in two

This is similar to the Haskell function, except that the signature is
reverse to match the 'any' and 'all' Python functions.

Fix cluster verify with simulate-errors

In simulate errors mode, the test "ntime_diff is not None" will be
ignored, and thus a None value will try to be formatted as %.01f. We
workaround this by formatting it before, and then only using %s, which
can format a 'None' value.
