After the addition of Storage Class support, readQuorum
and writeQuorum are decided on a per object basis, instead
of deployment wide static quorums.
This PR updates madmin api to remove readQuorum/writeQuorum
and add Standard storage class and reduced redundancy storage
class parity as return values. Since these parity values are
used to decide the quorum for each object.
Fixes#5378
This adds configurable data and parity options on a per object
basis. To use variable parity
- Users can set environment variables to cofigure variable
parity
- Then add header x-amz-storage-class to putobject requests
with relevant storage class values
Fixes#4997
This change brings public data-types such that
we can ask projects to implement gateway projects
externally than maintaining in our repo.
All publicly exported structs are maintained in object-api-datatypes.go
completePart --> CompletePart
uploadMetadata --> MultipartInfo
All other exported errors are at object-api-errors.go
This PR also does backend format change to 1.0.1
from 1.0.0. Backward compatible changes are still
kept to read the 'md5Sum' key. But all new objects
will be stored with the same details under 'etag'.
Fixes#4312
`disksUnavailable` healStatus constant indicates that a given object
needs healing but one or more of disks requiring heal are offline. This
can be used by admin heal API consumers to distinguish between a
successful heal and a no-op since the outdated disks were offline.
These messages based on our prep stage during XL
and prints more informative message regarding
drive information.
This change also does a much needed refactoring.
This is necessary for calculating the total storage
capacity from object layer. This value is also needed for
browser UI.
Buckets used to carry this information, this patch
deprecates this feature.
It is the bucket and volumes which needs to have this
value rather than the DiskInfo API itself. Eventually
this can be extended to show disk usage per
Buckets/Volumes whenever we have that functionality.
For now since buckets/volumes are thinly provisioned
this is the right approach.
- Move fs-definitions.go and break them into fs-datatypes.go, fs-bucket-acl.go
and fs-utils.go
- Move api-definitions.go to api-response.go, where they should be.
- Move web-definitions to its related handlers.
- limit list buckets to limit only 100 buckets, all uppercase buckets
are now lowercase and work transparently with all calls.
- Change disk.Stat to disk.GetInfo and return back disk.Info{} struct.
- Introduce new ioutils package which implements ReadDirN(path, n),
ReadDirNamesN(path, n)
Remove option of providing Technique and handling errors based on that
choose a matrix type automatically based on number of data blocks.
INTEL recommends on using cauchy for consistent invertible matrices,
while vandermonde is faster we should default to cauchy for large
data blocks.
