When the prefix field is not provided in the remote source of a yaml
replication job, the code fails to do listing and makes replication
successful. This commit fixes it.
This change adds a consistent nonce to ensure
that multipart uploads are deterministic on a
per-part basis.
Thanks to @klauspost for the work here minio/sio@3cd3734
locks handed by different pools would become non-compete for
multi-object delete request, this is wrong for obvious
reasons.
New locking implementation and revamp will rewrite multi-object
lock anyway, this is a workaround for now.
Currently, the bucket events and replication targets are only reloaded
with buckets that failed to load during the first cluster startup,
which is wrong because if one bucket change was done in one node but
that node was not able to notify other nodes; the other nodes will
reload the bucket metadata config but fails to set the events and bucket
targets in the memory.
when a hung drive is hot-unplugged, the server might go
into a loop where the previous `format.json` is somehow
still accessible to the process, we try to re-init() drives,
but that seems to cause a previous goroutine to hang around
since it is not canceled away when the drive is closed.
Bonus: add deadline for immediate purge routine, to unblock
it if the drive is blocking mutations.
if a user policy is found, avoid reading from the drives
for missing group mappings, group mappings are not mandatory
and conditional.
This PR restores the older behavior while making sure that
if a direct user policy is not found, we would still attempt
to load from the group from the drives.
This commit simplifies and optimizes the decryption of large (multipart)
objects. This PR does two things:
- Re-write the init logic for the decryption reader
- Reduce the number of OEK decryptions
Before, the init logic copied some SSE HTTP request headers to
parse them later. This is simplified to parsing them right away. This
removes some fields from the decryption reader struct.
Further, the decryption reader decrypted the OEK using the client-provided
key (SSE-C) or the KMS (SSE-S3 / SSE-KMS) for each part. This is redundant
since the OEK is the same for all parts. In particular, a KMS call might be a
network request. Now, the OEK is decrypted once for the entire multipart object.
This should improve latency when reading encrypted multipart objects
and reduce requests to the KMS.

Use Walk(), which is a recursive listing with versioning, to check if
the bucket has some objects before being removed. This is beneficial
because the bucket can contain multiple dangling objects in multiple
drives.
Also, this will prevent a bug where a bucket is deleted in a deployment
that has many erasure sets but the bucket contains one or few objects
not spread to enough erasure sets.
Currently, retry healing of a new drive healing does not reset
HealedBuckets means that the next healing retry will skip those
buckets. The commit will fix this behavior.
Also, the skipped objects counter will include objects uploaded
that are uploaded after the healing is started.
sftp sends local requests to the S3 port while passing the session token
header when the account corresponds to a service account. However, this
is not permitted and will throw an error: "The security token included in the
request is invalid"
This commit will avoid passing the session token to the upper layer that
initializes MinIO client to avoid this error.
Sometimes, we need historical information in .healing.bin, such as the
number of expired objects that the healing avoids to heal and that can
create drive usage disparency in the same erasure set. For that reason,
this commit will not remove .healing.bin anymore and it will have a new
field called Finished so we know healing is finished in that drive.
Services are unfrozen before `initBackgroundReplication` is finished. This means that
the globalReplicationStats write is racy. Switch to an atomic pointer.
Provide the `ReplicationPool` with the stats, so it doesn't have to be grabbed
from the atomic pointer on every use.
All other loads and checks are nil, and calls return empty values when stats
still haven't been initialized.
* Allow a maximum of 10 seconds to start profiling operations.
* Download up to 16 profiles concurrently, but only allow 10 seconds for
each (does not include write time).
* Add cluster info as the first operation.
* Ignore remote download errors.
* Stop remote profiles if the request is terminated.
If the site replication is enabled and the code tries to extract jwt
claims while the site replication service account credentials are still
not loaded yet, the code will enter an infinite loop, causing in a
high CPU usage.
Another possibility of the infinite loop is having some service accounts
created by an old deployment version where the service account JWT was
signed by the root credentials, but not anymore.
This commit will remove the possibility of the infinite loop in the code
and add root credential fallback to extract claims from old service
accounts.
move away from map[string]interface{} to map[string]string
to simplify the audit, and also provide concise information.
avoids large allocations under load(), reduces the amount
of audit information generated, as the current implementation
was a bit free-form. instead all datastructures must be
flattened.
Previously, we checked if we had a quorum on the DataDir value.
We are removing this check, which allows reading objects with different
DataDir values in a few drives (due to a rebalance-stop race bug)
provided their eTags or ModTimes match.
Since a lot of operations load from storage, do remote calls, add a 10 second timeout to each operation.
This should make `mc admin info` return values even under extreme conditions.
- optimize writing part.N.meta by writing both part.N
and its meta in sequence without network component.
- remove part.N.meta, part.N which were partially success
ful, in quorum loss situations during renamePart()
- allow for strict read quorum check arbitrated via ETag
for the given part number, this makes it double safer
upon final commit.
- return an appropriate error when read quorum is missing,
instead of returning InvalidPart{}, which is non-retryable
error. This kind of situation can happen when many
nodes are going offline in rotation, an example of such
a restart() behavior is statefulset updates in k8s.
fixes#20091
during rebalance stop, it can possibly happen that
Put() would race by overwriting the same object again.
This may very well if done "successfully" it can
potentially proceed to delete the object from the pool,
causing data loss.
This PR enhances #20233 to handle more scenarios such
as these.
Rebalance-stop can race with ongoing rebalance operations. This change
prevents these operations from overwriting objects by checking the source
and destination pool indices are different.
this allows for de-duplicating the callers when called
concurrently, allowing for bucketmetadata reads to be
single call. All concurrent callers will get the same data
as the first one.
Fix a regression in #19733 where TTFB metrics for all APIs except
GetObject were removed in v2 and v3 metrics. This causes breakage for
existing v2 metrics users. Instead we continue to send TTFB for all APIs
in V2 but only send for GetObject in V3.
allow multipart uploads expiration to be dyamic
It would seem like the new values will take effect
only after a restart for changes in multipart_expiration.
This PR fixes this by making it dynamic as it should have
been.
deadlines per moveToTrash() allows for a more granular timeout
approach for syscalls, instead of an aggregate timeout.
This PR also enhances multipart state cleanup to be optimal by
removing 100's of multipart network rename() calls into single
network call.
context deadline was introduced to avoid a slow transfer from blocking
replication queue(s) shared by other buckets that may not be under throttling.
This PR removes this context deadline for larger objects since they are
anyway restricted to a limited set of workers. Otherwise, objects would
get dequeued when the throttle limit is exceeded and cannot proceed
within the deadline.
epoll contention on TCP causes latency build-up when
we have high volume ingress. This PR is an attempt to
relieve this pressure.
upstream issue https://github.com/golang/go/issues/65064
It seems to be a deeper problem; haven't yet tried the fix
provide in this issue, but however this change without
changing the compiler helps.
Of course, this is a workaround for now, hoping for a
more comprehensive fix from Go runtime.
- ReadVersion
- ReadFile
- ReadXL
Further changes include to
- Compact internode resource RPC paths
- Compact internode query params
To optimize on parsing by gorilla/mux as the
length of this string increases latency in
gorilla/mux - reduce to a meaningful string.
the main reason is to let Go net/http perform necessary
book keeping properly, and in essential from consistency
point of view its GETs all the way.
Deprecate sendFile() as its buggy inside Go runtime.
For a non-tiered object, MinIO requires that EcM (# of data blocks) of
xl.meta agree, corresponding to the number of data blocks needed to
read this object.
OTOH, tiered objects have metadata in the hot tier and data in the
warm tier. The data and its integrity are offloaded to the warm tier. This
allows us to reduce the read quorum from EcM (typically > N/2, where N -
erasure stripe width) to N/2 + 1. The simple majority of metadata
ensures consensus on what the object is and where it is
located.
When a drive is in a failed state when a single node multiple drives
deployment is started, a replacement of a fresh disk will not be
properly healed unless the user restarts the node.
Fix this by always adding the new fresh disk to globalLocalDrivesMap. Also
remove globalLocalDrives for simplification, a map to store local node
drives can still be used since the order of local drives of a node is
not defined.
kms: Expose API available when bucket federation is enabled
When bucket federation feature is enabled, KMS API will not work, such
as `mc admin kms key list`
The commit will fix the issue by disabling bucket forwarding when this
is a KMS request.
Tracing syscalls, opening and reading an `xl.meta` looks like this:
```
openat(AT_FDCWD, "/mnt/drive1/ss8-old/testbucket/ObjSize4MiBThreads72/(554O51H/peTb(0iztdbTKw59.csv/xl.meta", O_RDONLY|O_NOATIME|O_CLOEXEC) = 34 <0.000>
fcntl(34, F_GETFL) = 0x48000 (flags O_RDONLY|O_LARGEFILE|O_NOATIME) <0.000>
fcntl(34, F_SETFL, O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_NOATIME) = 0 <0.000>
epoll_ctl(4, EPOLL_CTL_ADD, 34, {events=EPOLLIN|EPOLLOUT|EPOLLRDHUP|EPOLLET, data={u32=3172471557, u64=8145488475984499461}}) = -1 EPERM (Operation not permitted) <0.000>
fcntl(34, F_GETFL) = 0x48800 (flags O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_NOATIME) <0.000>
fcntl(34, F_SETFL, O_RDONLY|O_LARGEFILE|O_NOATIME) = 0 <0.000>
fstat(34, {st_mode=S_IFREG|0644, st_size=354, ...}) = 0 <0.000>
read(34, "XL2 \1\0\3\0\306\0\0\1P\2\2\1\304$\225\304\20\0\0\0\0\0\0\0\0\0\0\0"..., 354) = 354 <0.000>
close(34) = 0 <0.000>
```
Everything until `fstat` is the `os.Open` call.
Looking at the code: https://github.com/golang/go/blob/master/src/os/file_unix.go#L212-L243
It seems for every file it "tries" to see if it is pollable. This causes `syscall.SetNonblock(fd, true)` to be called. This is the first `F_SETFL`.
It then calls `f.pfd.Init("file", true)`. This will attempt to set it as pollable using `epoll_ctl`. This will always fail for files. It therefore calls `syscall.SetNonblock(fd, false)` resulting in the second `F_SETFL`.
If we set the `O_NONBLOCK` call on the initial open, we should avoid the 4 `fcntl` syscalls per file.
I don't see any way to avoid the `epoll_ctl` call, since kind is either `kindOpenFile` or `kindNonBlock`, so "pollable" will always be true. However avoiding 4 of 6 syscalls still seems worth it.
This should not have any effect, since files will end up with "nonblock" anyway.
allow non-inlined on disk to be inlined via
an unversioned ReadVersion() call, we only
need ReadXL() to resolve objects with multiple
versions only.
The choice of this block makes it to be dynamic
and chosen by the user via `mc admin config set`
Other bonus things
- Start measuring internode TTFB performance.
- Set TCP_NODELAY, TCP_CORK for low latency
removes contentious usage of mutexes in LRU, which
were never really reused in any manner; we do not
need it.
To trust hosts, the correct way is TLS certs; this PR completely
removes this dependency, which has never been useful.

Bonus: use `x-minio-time` as a nanosecond to avoid unnecessary
parsing logic of time strings instead of using a more
straightforward mechanism.
- Also, fix failure reporting at the end.
- Also, avoid parsing report objects when listing or resuming jobs, this
does not cause any bugs, it is only printing, not useful errors.
add unit test for v3 metrics for all its exposed endpoints
Bonus:
- support OpenMetrics encoding
- adds boot time for prometheus
- continueOnError is better to serve as
much metrics as possible.
```
curl http://localhost:9000/minio/metrics/v3/cluster/usage/buckets
```
Did not work as documented, due to the fact that there was a typo
in the bucket usage metrics registration group. This endpoint is
a cluster endpoint and does not require any `buckets` argument.
When creating the async listing, if the first request does not return within 3
minutes, it is stopped, since it isn't being kept alive.
Keep updating `lastHandout` while we are waiting for the initial request to be fulfilled.
When a fresh drive healing is finished, add more checks for the drive listing
errors. If any, re-list and heal again. Although this is an infrequent use
case to have listPathRaw() returning nil when minDisks is set to 1, we
still need to handle all possible use cases to avoid missing healing
any object.
Also, check for HealObject result to decide of an object is healed in the
fresh disk since HealObject returns nil if an object is healed in any
disk, and not in the new fresh drive.
In regular listing, this commit will avoid showing an object when its
latest version has a pending or failed deletion. In replicated setup.
It will also prevent showing older versions in the same case.
Also, sort the error map for multiple sites in ascending order
of deployment IDs, so that the error message generated is always
definitive order and same.
