only enable md5sum if explicitly asked by the client, otherwise
its not necessary to compute md5sum when SSE-KMS/SSE-C is enabled.
this is continuation of #17958
If network conditions have filled the output queue before a reconnect happens blocked sends could stop reconnects from happening. In short `respMu` would be held for a mux client while sending - if the queue is full this will never get released and closing the mux client will hang.
A) Use the mux client context instead of connection context for sends, so sends are unblocked when the mux client is canceled.
B) Use a `TryLock` on "close" and cancel the request if we cannot get the lock at once. This will unblock any attempts to send.
data-dir not being present is okay, however we can still
rely on the `rename()` atomic call instead of relying on
write xl.meta write which may truncate the io.EOF.
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
the PR in #16541 was incorrect and hand wrong assumptions
about the overall setup, revert this since this expectation
to have offline servers is wrong and we can end up with a
bigger chicken and egg problem.
This reverts commit 5996c8c4d5.
Bonus:
- preserve disk in globalLocalDrives properly upon connectDisks()
- do not return 'nil' from newXLStorage(), getting it ready for
the next set of changes for 'format.json' loading.
The previous logic of calculating per second values for disk io stats
divides the stats by the host uptime. This doesn't work in k8s
environment as the uptime is of the pod, but the stats (from
/proc/diskstats) are from the host.
Fix this by storing the initial values of uptime and the stats at the
timme of server startup, and using the difference between current and
initial values when calculating the per second values.
globalLocalDrives seem to be not updated during the
HealFormat() leads to a requirement where the server
needs to be restarted for the healing to continue.

where `a/prefix` is an object which does not have `/` at the end,
we do not have to aggressively recursively delete all the sub-folders
as well. Instead convert the call into self contained to deleting
'xl.meta' and then subsequently attempting to Remove the parent.
Bonus: enable audit alerts for object versions
beyond the configured value, default is '100'
versions per object beyond which scanner will
alert for each such objects.
when we expand via pools, there is no reason to stick
with the same distributionAlgo as the rest. Since the
algo only makes sense with-in a pool not across pools.
This allows for newer pools to use newer codepaths to
avoid legacy file lookups when they have a pre-existing
deployment from 2019, they can expand their new pool
to be of a newer distribution format, allowing the
pool to be more performant.
