This change co-incides with another patch set which
reduces the writeQuorum requirement. With the
write quorum change it is now possible to support
6 disk configuration.
This patch also supports writing to a temporary file and renaming
rather than appending to an existing file. This helps in avoiding
inconsistent files.
Previously write quorum was set to (no. of disk / 2) + 3. As per new
change, the write quorum is set to (no. of disk / 2) + 2. This helps
to accommodate one more failure of disk.
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.
Remove usage of getFileVersionQuorumMap, instead use listFileVersions
to get the version list and extract higherVersion.
Fixes#1379Fixes#1378Fixes#1377
* xl/ListFiles: return as many objects as requested and take care of eof (#1361)
* xl/ListFiles: fix review comments.
* xl/ListFiles: Add windows filepath translation.
* xl/ListFiles: Use slashSeparator instead of "/". Remove filepath.FromSlash() as golang-windows takes care of it automatically.
* xl/selfheal: selfheal based on read quorum on GET
* xl: getReadableDisks() also returns whether self-heal is needed so that this info can be used by ReadFile/SelfHeal/StatFile.
* xl: trigger selfheal from StatFile.
