nas: Clean stale background appended files (#14295) 
When more than one gateway reads and writes from the same mount point
and there is a load balancer pointing to those gateways. Each gateway 
will try to create its own temporary append file but fails to clear it later 
when not needed.

This commit creates a routine that checks all upload IDs saved in
multipart directory and remove any stale entry with the same upload id
in the memory and in the temporary background append folder as well.

fs: Retry listing if no marker (#14221) 
Retry listings, when no next marker is returned and the result isn't truncated.

This can happen when an object is queued, but no info can be fetched.

Fixes #14190

remove FIFO bucket quota, use ILM expiration instead (#14206) 2022-01-31 11:07:04 -08:00

cached diskIDs are not needed for scanner healing (#14170) 
This PR removes an unnecessary state that gets
passed around for DiskIDs, which is not necessary
since each disk exactly knows which pool and which
set it belongs to on a running system.

Currently cached DiskId's won't work properly
because it always ends up skipping offline disks
and never runs healing when disks are offline, as
it expects all the cached diskIDs to be present
always. This also sort of made things in-flexible
in terms perhaps a new diskID for `format.json`.
(however this is not a big issue)

This is an unnecessary requirement that healing
via scanner needs all drives to be online, instead
healing should trigger even when partial nodes
and drives are available this ensures that we
keep the SLA in-tact on the objects when disks
are offline for a prolonged period of time.

MakeBucket: Delete leftover buckets on error (#13368) 
In (erasureServerPools).MakeBucketWithLocation deletes the created 
buckets if any set returns an error.

Add `NoRecreate` option, which will not recreate the bucket 
in `DeleteBucket`, if the operation fails.

Additionally use context.Background() for operations we always want to be performed.

---------                     -------

```

Furthermore allow `inspect` to do direct decode from `mc`, for example:

```
λ mc admin inspect --json local2/testbucket/nyc-taxi-data-10M.csv.zst/*|inspect -json
Output decrypted to inspect.5f0643b2.zip
```

- Correct error, forward non-EOF errors.
- Add some extra safety. Log FNF when no files.
- Add `xl-meta` zip support.
For `xl-meta` multiple inputs output object with names as key.
Automatically switches `xl-meta` to single-line output when multiple objects.
Add double-star wildcard support to xl-meta input.

feat: add dynamic usage cache (#12229) 
A cache structure will be kept with a tree of usages.
The cache is a tree structure where each keeps track 
of its children.

An uncompacted branch contains a count of the files 
only directly at the branch level, and contains link to 
children branches or leaves.

The leaves are "compacted" based on a number of properties.
A compacted leaf contains the totals of all files beneath it.

A leaf is only scanned once every dataUsageUpdateDirCycles,
rarer if the bloom filter for the path is clean and no lifecycles 
are applied. Skipped leaves have their totals transferred from 
the previous cycle.

A clean leaf will be included once every healFolderIncludeProb 
for partial heal scans. When selected there is a one in 
healObjectSelectProb that any object will be chosen for heal scan.

Compaction happens when either:

- The folder (and subfolders) contains less than dataScannerCompactLeastObject objects.
- The folder itself contains more than dataScannerCompactAtFolders folders.
- The folder only contains objects and no subfolders.
- A bucket root will never be compacted.

Furthermore, if a has more than dataScannerCompactAtChildren recursive 
children (uncompacted folders) the tree will be recursively scanned and the 
branches with the least number of objects will be compacted until the limit 
is reached.

This ensures that any branch will never contain an unreasonable amount 
of other branches, and also that small branches with few objects don't 
take up unreasonable amounts of space.

Whenever a branch is scanned, it is assumed that it will be un-compacted
before it hits any of the above limits. This will make the branch rebalance 
itself when scanned if the distribution of objects has changed.

TLDR; With current values: No bucket will ever have more than 10000 
child nodes recursively. No single folder will have more than 2500 child 
nodes by itself. All subfolders are compacted if they have less than 500 
objects in them recursively.

We accumulate the (non-deletemarker) version count for paths as well, 
since we are changing the structure anyway.

fix: improve NewObjectReader implementation for careful cleanup usage (#12199) 
cleanup functions should never be cleaned before the reader is
instantiated, this type of design leads to situations where order
of lockers and places for them to use becomes confusing.

Allow WithCleanupFuncs() if the caller wishes to add cleanupFns
to be run upon close() or an error during initialization of the
reader.

Also make sure streams are closed before we unlock the resources,
this allows for ordered cleanup of resources.

lock: Always cancel the returned Get(R)Lock context (#12162) 
* lock: Always cancel the returned Get(R)Lock context

There is a leak with cancel created inside the locking mechanism. The
cancel purpose was to cancel operations such erasure get/put that are
holding non-refreshable locks.

This PR will ensure the created context.Cancel is passed to the unlock
API so it will cleanup and avoid leaks.

* locks: Avoid returning nil cancel in local lockers

Since there is no Refresh mechanism in the local locking mechanism, we
do not generate a new context or cancel. Currently, a nil cancel
function is returned but this can cause a crash. Return a dummy function
instead.

 2021-04-27 08:24:44 -07:00
Krishnan Parthasarathi c829e3a13b Support for remote tier management (#12090) 
With this change, MinIO's ILM supports transitioning objects to a remote tier.
This change includes support for Azure Blob Storage, AWS S3 compatible object
storage incl. MinIO and Google Cloud Storage as remote tier storage backends.

Some new additions include:

 - Admin APIs remote tier configuration management

 - Simple journal to track remote objects to be 'collected'
   This is used by object API handlers which 'mutate' object versions by
   overwriting/replacing content (Put/CopyObject) or removing the version
   itself (e.g DeleteObjectVersion).

 - Rework of previous ILM transition to fit the new model
   In the new model, a storage class (a.k.a remote tier) is defined by the
   'remote' object storage type (one of s3, azure, GCS), bucket name and a
   prefix.

* Fixed bugs, review comments, and more unit-tests

- Leverage inline small object feature
- Migrate legacy objects to the latest object format before transitioning
- Fix restore to particular version if specified
- Extend SharedDataDirCount to handle transitioned and restored objects
- Restore-object should accept version-id for version-suspended bucket (#12091)
- Check if remote tier creds have sufficient permissions
- Bonus minor fixes to existing error messages

Various improvements in replication (#11949) 
- collect real time replication metrics for prometheus.
- add pending_count, failed_count metric for total pending/failed replication operations.

- add API to get replication metrics

- add MRF worker to handle spill-over replication operations

- multiple issues found with replication
- fixes an issue when client sends a bucket
 name with `/` at the end from SetRemoteTarget
 API call make sure to trim the bucket name to 
 avoid any extra `/`.

- hold write locks in GetObjectNInfo during replication
  to ensure that object version stack is not overwritten
  while reading the content.

- add additional protection during WriteMetadata() to
  ensure that we always write a valid FileInfo{} and avoid
  ever writing empty FileInfo{} to the lowest layers.

remove GetObject from ObjectLayer interface (#11635) 
This commit removes the `GetObject` method
from the `ObjectLayer` interface.

The `GetObject` method is not longer used by
the HTTP handlers implementing the high-level
S3 semantics. Instead, they use the `GetObjectNInfo`
method which returns both, an object handle as well
as the object metadata.

Therefore, it is no longer necessary that a concrete
`ObjectLayer` implements `GetObject`.
