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.
- bucket metadata does not need to look for legacy things
anymore if b.Created is non-zero
- stagger bucket metadata loads across lots of nodes to
avoid the current thundering herd problem.
- Remove deadlines for RenameData, RenameFile - these
calls should not ever be timed out and should wait
until completion or wait for client timeout. Do not
choose timeouts for applications during the WRITE phase.
- increase R/W buffer size, increase maxMergeMessages to 30
Depending on when the context cancelation is picked up the handler may return and close the channel before `SubscribeJSON` returns, causing:
```
Feb 05 17:12:00 s3-us-node11 minio[3973657]: panic: send on closed channel
Feb 05 17:12:00 s3-us-node11 minio[3973657]: goroutine 378007076 [running]:

Feb 05 17:12:00 s3-us-node11 minio[3973657]: created by github.com/minio/minio/internal/pubsub.(*PubSub[...]).SubscribeJSON in goroutine 378010884

```
Wait explicitly for the goroutine to exit.
Bonus: Listen for doneCh when sending to not risk getting blocked there is channel isn't being emptied.
this fixes rare bugs we have seen but never really found a
reproducer for
- PutObjectRetention() returning 503s
- PutObjectTags() returning 503s
- PutObjectMetadata() updates during replication returning 503s
These calls return errors, and this perpetuates with
no apparent fix.
This PR fixes with correct quorum requirement.
To force limit the duration of STS accounts, the user can create a new
policy, like the following:
{
"Version": "2012-10-17",
"Statement": [{
"Effect": "Allow",
"Action": ["sts:AssumeRoleWithWebIdentity"],
"Condition": {"NumericLessThanEquals": {"sts:DurationSeconds": "300"}}
}]
}
And force binding the policy to all OpenID users, whether using a claim name or role
ARN.
disk tokens usage is not necessary anymore with the implementation
of deadlines for storage calls and active monitoring of the drive
for I/O timeouts.
Functionality kicking off a bad drive is still supported, it's just that
we do not have to serialize I/O in the manner tokens would do.
Interpret `null` inline policy for access keys as inheriting parent
policy. Since MinIO Console currently sends this value, we need to honor it
for now. A larger fix in Console and in the server are required.
Fixes#18939.
Allow internal types to support a `Recycler` interface, which will allow for sharing of common types across handlers.
This means that all `grid.MSS` (and similar) objects are shared across in a common pool instead of a per-handler pool.
Add internal request reuse of internal types. Add for safe (pointerless) types explicitly.
Only log params for internal types. Doing Sprint(obj) is just a bit too messy.
