create missing .minio.sys/config, .minio.sys/buckets during decommission (#14497) 2022-03-07 16:18:57 -08:00
Harshavardhana 7e803adf13
do not attempt force delete on bucket (#14452) 
caller needs to ask explicitly for force delete
otherwise, the force delete might end up deleting
an existing bucket with data.

fixes #14445

remove errCh usage from HealObjects() simplify it (#14414) 
errCh is not needed instead, rely on errs slice to
capture and return errors instead.

most probably fixes #14247

Klaus Post 60cd513a33
Fix leaked healing goroutines (#14322) 
Only the first `listAndHeal` would ever be able to write on errCh, blocking all others infinitely.

Instead read all errors but return the first non-nil, if any.

The intention appears to be that this should cancel on any error, 
so that part is kept. 

Regression from #13990

Refactor replication resync to be an active process (#14266) 
When resync is triggered, walk the bucket namespace and
resync objects that are unreplicated. This PR also adds
an API to report resync progress.

fix: allow danging objects to be purged properly deleteMultipleObjects() (#14273) 
Deleting bulk objects had an issue since the relevant versionID
is not passed through the layers to ensure that the dangling
object purge actually works cleanly.

This is a continuation of quorum related error returned by
multi-object delete API from #14248

This PR ensures that we pass down correct information as
well as extend the scope of dangling object detection.

remove FIFO bucket quota, use ILM expiration instead (#14206) 2022-01-31 11:07:04 -08:00
Harshavardhana 5a9f133491
speed up startup sequence for all operations (#14148) 
This speed-up is intended for faster startup times
for almost all MinIO operations. Changes here are

- Drives are not re-read for 'format.json' on a regular
  basis once read during init is remembered and refreshed
  at 5 second intervals.

- Do not do O_DIRECT tests on drives with existing 'format.json'
  only fresh setups need this check.

- Parallelize initializing erasureSets for multiple sets.

- Avoid re-reading format.json when migrating 'format.json'
  from really old V1->V2->V3

- Keep a copy of local drives for any given server in memory
  for a quick lookup.

add more directory marker tests and fix a bug (#13871) 
ListObjects() should never list a delete-marked folder
if latest is delete marker and delimiter is not provided.

ListObjectVersions() should list a delete-marked folder
even if latest is delete marker and delimiter is not
provided.

Enhance further versioning listing on the buckets

Harshavardhana dcff6c996d
fix: do not list delete-marked objects (#13864) 
delete marked objects should not be considered
for listing when listing is delimited, this issue
as introduced in PR #13804 which was mainly to
address listing of directories in listing when
delimited.

This PR fixes this properly and adds tests to
ensure that we behave in accordance with how
an S3 API behaves for ListObjects() without
versions.

Improve listing consistency with version merging (#13723) 2021-12-02 11:29:16 -08:00
Harshavardhana 21c868a646
fix: do not ignore delete-marker directories in ListObjects() (#13804) 
Following scenario such as objects that exist inside a
prefix say `folder/` must be included in the listObjects()
response.

```
2aa16073-387e-492c-9d59-b4b0b7b6997a v2 DEL folder/
a5b9ce68-7239-4921-90ab-20aed402c7a2 v1 PUT folder/
f2211798-0eeb-4d9e-9184-fcfeae27d069 v1 PUT folder/1.txt
```

Current master does not handle this scenario, because it
ignores the top level delete-marker on folders. This is
however unexpected. It is expected that list-objects returns
the top level prefix in this situation.

```
aws s3api list-objects --bucket harshavardhana --prefix unique/ \
     --delimiter / --profile minio --endpoint-url http://localhost:9000
{
    "CommonPrefixes": [
        {
            "Prefix": "unique/folder/"
        }
    ]
}
```

There are applications in the wild such as Hadoop s3a connector
that exploit this behavior and expect the folder to be present
in the response.

This also makes the behavior consistent with AWS S3.

add delete-marker proactively in DeleteObject() (#13795) 
single object delete was not working properly
on a bucket when versioning was suspended,
current version 'null' object was never removed.

ignore swapped drives instead of throwing errors (#13655) 
- add checks such that swapped disks are detected
  and ignored - never used for normal operations.

- implement `unrecognizedDisk` to be ignored with
  all operations returning `errDiskNotFound`.

- also add checks such that we do not load unexpected
  disks while connecting automatically.

- additionally humanize the values when printing the errors.

Bonus: fixes handling of non-quorum situations in
getLatestFileInfo(), that does not work when 2 drives
are down, currently this function would return errors
incorrectly.

fix: simplify loading IAM users to avoid using regular ListObjects() (#13392) 
- avoids relying in listQuorum from the underlying listObjects()
  and potentially missing entries if any.

- avoid the entire merging logic etc, listing raw set by set
  and loading whatever is found is cleaner when dealing with
  a large cluster for IAM metadata.

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.

fix: improve bucket deletes we were leaving behind few files (#13364) 
bucket deletes should purge entire bucket metadata
appropriately, use rename() to move the metadata files
to trash folder,

for dangling buckets instead of doing recursive deletes,
rename such buckets to trash folder as well.

Bonus: reduce retry duration for listing to 200ms

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.

fix: multi-pool setup make sure acquire locks properly (#13280) 
This was a regression introduced in '14bb969782'
this has the potential to cause corruption when
there are concurrent overwrites attempting to update
the content on the namespace.

This PR adds a situation where PutObject(), CopyObject()
compete properly for the same locks with NewMultipartUpload()
however it ends up turning off competing locks for the actual
object with GetObject() and DeleteObject() - since they do not
compete due to concurrent I/O on a versioned bucket it can lead
to loss of versions.

This PR fixes this bug with multi-pool setup with replication
that causes corruption of inlined data due to lack of competing
locks in a multi-pool setup.

Instead CompleteMultipartUpload holds the necessary
locks when finishing the transaction, knowing the exact
location of an object to schedule the multipart upload
doesn't need to compete in this manner, a pool id location
for existing object.

healObject() should be non-blocking to ensure

listObjects optimized to handle max-keys=1 when prefix is object (#13000) 
Some applications albeit poorly written rather than using headObject
rely on listObjects to check for existence of object, this unusual
request always has prefix=(to actual object) and max-keys=1

handle this situation specially such that we can avoid readdir()
on the top level parent to avoid sorting and skipping, ensuring
that such type of listObjects() always behaves similar to a
headObject() call.
