This commit splits the liveness and readiness
handler into two separate handlers. In K8S, a
liveness probe is used to determine whether the
pod is in "live" state and functioning at all.
In contrast, the readiness probe is used to
determine whether the pod is ready to serve
requests.
A failing liveness probe causes pod restarts while
a failing readiness probe causes k8s to stop routing
traffic to the pod. Hence, a liveness probe should
be as robust as possible while a readiness probe
should be used to load balancing.

This patch takes care of loading the bucket configs of failed buckets
during the periodic refresh. This makes sure the event notifiers and
remote bucket targets are properly initialized.
users might use MinIO on NFS, GPFS that provide dynamic
inodes and may not even have a concept of free inodes.
to allow users to use MinIO on top of GPFS relax the
free inode check.
* creating a byte buffer for SFTP file segments
* Adding an error condition for when there are
remaining segments in the queue
* Simplification of the queue using a map
it is possible that ILM or Deletes got triggered on batch
of objects that we are attempting to batch replicate, ignore
this scenario as valid behavior.
sendfile implementation to perform DMA on all platforms
Go stdlib already supports sendfile/splice implementations
for
- Linux
- Windows
- *BSD
- Solaris
Along with this change however O_DIRECT for reads() must be
removed as well since we need to use sendfile() implementation
The main reason to add O_DIRECT for reads was to reduce the
chances of page-cache causing OOMs for MinIO, however it would
seem that avoiding buffer copies from user-space to kernel space
this issue is not a problem anymore.
There is no Go based memory allocation required, and neither
the page-cache is referenced back to MinIO. This page-
cache reference is fully owned by kernel at this point, this
essentially should solve the problem of page-cache build up.
With this now we also support SG - when NIC supports Scatter/Gather

`monitorAndConnectEndpoints` will continue to attempt to reconnect offline disks.
Since disks were never closed, a `MarkOffline` would continue to try to check these disks forever.
Close previous disks.
replace io.Discard usage to fix NUMA copy() latencies
On NUMA systems copying from 8K buffer allocated via
io.Discard leads to large latency build-up for every
```
copy(new8kbuf, largebuf)
```
can in-cur upto 1ms worth of latencies on NUMA systems
due to memory sharding across NUMA nodes.
Fix various regressions from #18029
* If context is canceled the token is never returned. This will lead to scanner being unable to save and deadlocking.
* Fix backup not being able to get any data (hr empty)
* Reduce backup timeout.
Tiering statistics have been broken for some time now, a regression
was introduced in 6f2406b0b6
Bonus fixes an issue where the objects are not assumed to be
of the 'STANDARD' storage-class for the objects that have
not yet tiered, this should be conditional based on the object's
metadata not a default assumption.
This PR also does some cleanup in terms of implementation,
fixes#18070
https://github.com/minio/minio/pull/18307 partially removed the duplicate upload id check.
While I can't really see how ListDir can return duplicate entries, let's re-add it, since it is a cheap sanity check.
This commit changes the container base image
from ubi-minimal to ubi-micro.
The docker build process happens now in two stages.
The build stage:
- downloads the latest CA certificate bundle
- downloads MinIO binary (for requested version/os/arch)
- downloads MinIO binary signature and verifies it
using minisign
Then it creates an image based on ubi-micro with just
the minio binary was downloaded and verified during the
build stage.
The build stage is simplified to just verifying the
minisign signature.
