This whitespace different is thought to be breaking
the build.
The differences in white space are hypothesized to happen
because trailing whitespace is chomped by some people's
editors but not others.
The trailing whitespace is enough of a difference to make
hack/verify-api-references-docs.sh think that the
docs are not different.
I think this is not caught by presubmits because different
versions of diff are doing different things with trailing
whitespace, even though `-Bw` flags are passed.
This enables use of software or hardware transports viz. be2iscsi,
bnx2i, cxgb3i, cxgb4i, qla4xx, iser and ocs. The default transport
(tcp) happens to be called "default".
Use of non-default transports changes the disk path to the following format:
/dev/disk/by-path/pci-<pci_id>-ip-<portal>-iscsi-<iqn>-lun-<lun_id>
- PeriodSeconds - How often to probe
- SuccessThreshold - Number of successful probes to go from failure to success state
- FailureThreshold - Number of failing probes to go from success to failure state
This commit includes to changes in behavior:
1. InitialDelaySeconds now defaults to 10 seconds, rather than the
kubelet sync interval (although that also defaults to 10 seconds).
2. Prober only retries on probe error, not failure. To compensate, the
default FailureThreshold is set to the maxRetries, 3.
