console service should be shutdown last once all shutdown
sequences are complete, this is to ensure that we do not
prematurely kill the server before it cleans up the
`.minio.sys/tmp/uuid` folder.
NOTE: this only applies to NAS gateway setup.
Use a single allocation for reading the file, not the growing buffer of `io.ReadAll`.
Reuse the write buffer if we can when writing metadata in RenameData.
* reduce extra getObjectInfo() calls during ILM transition
This PR also changes expiration logic to be non-blocking,
scanner is now free from additional costs incurred due
to slower object layer calls and hitting the drives.
* move verifying expiration inside locks
A multi resources lock is a single lock UID with multiple associated
resources. This is created for example by multi objects delete
operation. This commit changes the behavior of Refresh() to iterate over
all locks having the same UID and refresh them.
Bonus: Fix showing top locks for multi delete objects
#11878 added "keepHTTPResponseAlive" to CreateFile requests.
The problem is that it will begin writing to the response before the
body is read after 10 seconds. This will abort the writes on the
client-side, since it assumes the server has received what it wants.
The proposed solution here is to monitor the completion of the body
before beginning to send keepalive pings.
Fixes observed high number of goroutines stuck in `io.Copy` in
`github.com/minio/minio/cmd.(*xlStorage).CreateFile` and
`(*storageRESTClient).CreateFile` stuck in `http.DrainBody`.
In the event when a lock is not refreshed in the cluster, this latter
will be automatically removed in the subsequent cleanup of non
refreshed locks routine, but it forgot to clean the local server,
hence having the same weird stale locks present.
This commit will remove the lock locally also in remote nodes, if
removing a lock from a remote node will fail, it will be anyway
removed later in the locks cleanup routine.
Currently in master this can cause existing
parent users to stop working and lead to
credentials getting overwritten.
```
~ mc admin user add alias/ minio123 minio123456
```
```
~ mc admin user svcacct add alias/ minio123 \
--access-key minio123 --secret-key minio123456
```
This PR rejects all such scenarios.
Faster healing as well as making healing more
responsive for faster scanner times.
also fixes a bug introduced in #13079, newly replaced
disks were not healing automatically.
- remove sourceCh usage from healing
we already have tasks and resp channel
- use read locks to lookup globalHealConfig
- fix healing resolver to pick candidates quickly
that need healing, without this resolver was
unexpectedly skipping.
healObject() should be non-blocking to ensure
that scanner is not blocked for a long time,
this adversely affects performance of the scanner
and also affects the way usage is updated
subsequently.
This PR allows for a non-blocking behavior for
healing, dropping operations that cannot be queued
anymore.
Synchronize bucket cycles so it is much more
likely that the same prefixes will be picked up
for scanning.
Use the global bloom filter cycle for that.
Bump bloom filter versions to clear those.
The intention is to list values of sys config that can potentially
impact the performance of minio.
At present, it will return max value configured for rlimit

proceed to heal the cluster when all the
drives in a set have failed, this is extremely
rare occurrence but even if it happens we allow
the cluster to be functional.
A recent regression caused new disks not being re-formatted. In the old
code, a disk needed be 'online' to be chosen to be formatted but the
disk has to be already formatted for XL storage IsOnline() function to
return true.
It is enough to check if XL storage is nil or not if we want to avoid
formatting root disks.

markRootDisksAsDown() relies on disk info even if the
disk is unformatted. Therefore, we should always return
DiskInfo data even when DiskInfo storage API returns
errUnformattedDisk
`mc admin heal` command will show servers/disks tolerance, for that
purpose, you need to know the number of parity disks for each storage
class.
Parity is always the same in all pools.
prefixes at top level create such as
```
~ mc mb alias/bucket/prefix
```
The prefix/ incorrect appears as prefix__XL_DIR__/
in the accountInfo output, make sure to trim '__XL_DIR__'
Objects uploaded in this format for example
```
mc cp /etc/hosts alias/bucket/foo/bar/xl.meta
mc ls -r alias/bucket/foo/bar
```
Won't list the object, handle this scenario.
Ensure that one call will succeed and others will serialize
Example failure without code in place:
