startup speed-up, currently getFormatErasureInQuorum()
would spend up to 2-3secs when there are 3000+ drives
for example in a setup, simplify this implementation
to use drive counts.
DeleteMarkers do not have a default quorum, i.e it is possible that
DeleteMarkers were created with n/2+1 quorum as well to make sure
that we satisfy situations such as those we need to make sure delete
markers only expect n/2 read quorum.
Additionally we should also look at additional metadata on the
actual objects that might have been "erasure" upgraded with new
parity when disks are down.
In such a scenario do not default to the standard storage class
parity, instead use the parityBlocks present on the FileInfo to
ensure that we are dealing with the correct quorum for READs and
DELETEs.
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
The healing code repeatedly tries to heal a root disk when it is empty
the reason is that connectEndpoint() returns errUnformattedDisk even
if the disk is a root disk. Changing that to returning another error
will avoid queueing the disk to the healing code in each connect disks
iteration.
some upgraded objects might not get listed due
to different quorum ratios across objects.
make sure to list all objects that satisfy the
maximum possible quorum.
This change allows the MinIO server to lookup users in different directory
sub-trees by allowing specification of multiple search bases separated by
semicolons.
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.
Wrong resource is being fetched, since idx is incremented, but mapID is reused.
Regression caused by #13454 - that part didn't optimize anything anyway.
Publish storage functions latency to help compare the performance
of different disks in a single deployment.
e.g.:
```
minio_node_disk_latency_us{api="storage.WalkDir",disk="/tmp/xl/1",server="localhost:9001"} 226
minio_node_disk_latency_us{api="storage.WalkDir",disk="/tmp/xl/2",server="localhost:9002"} 1180
minio_node_disk_latency_us{api="storage.WalkDir",disk="/tmp/xl/3",server="localhost:9003"} 1183
minio_node_disk_latency_us{api="storage.WalkDir",disk="/tmp/xl/4",server="localhost:9004"} 1625
```
