On a policy detach operation, if there are no policies remaining
attached to the user/group, remove the policy mapping file, instead of
leaving a file containing an empty list of policies.
Healing dangling buckets is conservative, and it is a typical use case to
fail to remove a dangling bucket because it contains some data because
healing danging bucket code is not allowed to remove data: only healing
the dangling object is allowed to do so.
reference format is constant for any lifetime of
a minio cluster, we do not have to ever replace
it during HealFormat() as it will never change.
additionally we should simply reject reference
formats that we do not understand early on.
GetActualSize() was heavily relying on o.Parts()
to be non-empty to figure out if the object is multipart or not,
However, we have many indicators of whether an object is multipart
or not.
Blindly assuming that o.Parts == nil is not a multipart, is an
incorrect expectation instead, multipart must be obtained via
- Stored metadata value indicating this is a multipart encrypted object.
- Rely on <meta>-actual-size metadata to get the object's actual size.
This value is preserved for additional reasons such as these.
- ETag != 32 length
support proxying of tagging requests in active-active replication
Note: even if proxying is successful, PutObjectTagging/DeleteObjectTagging
will continue to report a 404 since the object is not present locally.
New intervals:
[1024B, 64KiB)
[64KiB, 256KiB)
[256KiB, 512KiB)
[512KiB, 1MiB)
The new intervals helps us see object size distribution with higher
resolution for the interval [1024B, 1MiB).
- HealFormat() was leaking healthcheck goroutines for
disks, we are only interested in enabling healthcheck
for the newly formatted disk, not for existing disks.
- When disk is a root-disk a random disk monitor was
leaking while we ignored the drive.
- When loading the disk for each erasure set, we were
leaking goroutines for the prepare-storage.go disks
which were replaced via the globalLocalDrives slice
- avoid disk monitoring utilizing health tokens that
would cause exhaustion in the tokens, prematurely
which were meant for incoming I/O. This is ensured
by avoiding writing O_DIRECT aligned buffer instead
write 2048 worth of content only as O_DSYNC, which is
sufficient.
Add a hidden configuration under the scanner sub section to configure if
the scanner should sleep between two objects scan. The configuration has
only effect when there is no drive activity related to s3 requests or
healing.
By default, the code will keep the current behavior which is doing
sleep between objects.
To forcefully enable the full scan speed in idle mode, you can do this:
`mc admin config set myminio scanner idle_speed=full`
fixes#18724
A regression was introduced in #18547, that attempted
to file adding a missing `null` marker however we
should not skip returning based on versionID instead
it must be based on if we are being asked to create
a DEL marker or not.
The PR also has a side-affect for replicating `null`
marker permanent delete, as it may end up adding a
`null` marker while removing one.
This PR should address both scenarios.
NOTE: This feature is not retro-active; it will not cater to previous transactions
on existing setups.
To enable this feature, please set ` _MINIO_DRIVE_QUORUM=on` environment
variable as part of systemd service or k8s configmap.
Once this has been enabled, you need to also set `list_quorum`.
```
~ mc admin config set alias/ api list_quorum=auto`
```
A new debugging tool is available to check for any missing counters.
Following policies if present
```
"Condition": {
"IpAddress": {
"aws:SourceIp": [
"54.240.143.0/24",
"2001:DB8:1234:5678::/64"
]
}
}
```
And client is making a request to MinIO via IPv6 can
potentially crash the server.
Workarounds are turn-off IPv6 and use only IPv4
This PR also increases per node bpool memory from 1024 entries
to 2048 entries; along with that, it also moves the byte pool
centrally instead of being per pool.
minio_node_tier_ttlb_seconds - Distribution of time to last byte for streaming objects from warm tier
minio_node_tier_requests_success - Number of requests to download object from warm tier that were successful
minio_node_tier_requests_failure - Number of requests to download object from warm tier that failed
SUBNET now has a v2 of license that is returned in the new key
`license_v2`. mc will start reading and storing the same. (The old key
`license` is deprecated but is still available in SUBNET response to
ensure that the current released version of minio doesn't break)
