Create new code paths for multiple subsystems in the code. This will
make maintaing this easier later.
Also introduce bugLogIf() for errors that should not happen in the first
place.
there can be a sudden spike in tiny allocations,
due to too much auditing being done, also don't hang
on the
```
h.logCh <- entry
```
after initializing workers if you do not have a way to
dequeue for some reason.
Add a new function logger.Event() to send the log to Console and
http/kafka log webhooks. This will include some internal events such as
disk healing and rebalance/decommissioning
it is entirely possible that a rebalance process which was running
when it was asked to "stop" it failed to write its last statistics
to the disk.
After this a pool expansion can cause disruption and all S3 API
calls would fail at IsPoolRebalancing() function.
This PRs makes sure that we update rebalance.bin under such
conditions to avoid any runtime crashes.
A continuation of PR #17479 for rebalance behavior must
also match the decommission behavior.
Fixes bug where rebalance would ignore rebalancing object
versions after one of the version returned "ObjectNotFound"
A state is updated with a delete marker, which does not have parity or
data blocks defined, which can cause the integer divide by zero panics.
This commit fixes to avoid panics.
