Harshavardhana d65101a8c8 XL: Implement strided erasure distribution. (#1772) 
Strided erasure distribution uses a new randomized
block distribution for each Put operation. This
information is captured inside `xl.json` for subsequent
Get operations.

Harshavardhana 34e9ad24aa XL: Introduce new API StorageInfo. (#1770) 
This is necessary for calculating the total storage
capacity from object layer. This value is also needed for
browser UI.

deprecates this feature.

   appropriately.

Harshavardhana 553fdb9211 XL: Bring in support for object versions written during writeQuorum. (#1762) 
Erasure is initialized as needed depending on the quorum and onlineDisks.
This way we can manage the quorum at the object layer.
 2016-05-28 15:15:53 -07:00
Harshavardhana cae4782973 XL: explicit deleteObject is not needed after rename failure. (#1760) 
Reason is renameObject() does deleteObject() upon writeQuorum
failure if not keeps the successfully renamed parts if we have
reached readQuorum.

Krishnan Parthasarathi 584813e214 Used MINIO_PROFILE_DIR for saving profile information of a minio server (#1722) 
To specify the directory where profiling information should be saved
  ```
    export MINIO_PROFILE_DIR=/path/to/profile/dir
  ```
By default, profiling information would be saved in a directory created
using ioutil.TempDir, which would be displayed in stdout on starting the
minio server.

Harshavardhana e4240aa58f XL/objects: Initialize format.json outside of erasure. (#1640) 
Fixes #1636

New format now generates a UUID and includes it along with
the order of disks. So that UUID is the real order of disks
and on command line user is able to specify disks in any order.

This pre-dominantly solves our dilemma.

Andreas Linz f5dfa895a5 Exit with error code if minio server fails to start (#1704) 
This commit replaces the call to `errorIf` with `fatalIf`, so that the
minio server exits with an non-zero exit status if something fails, e.g.
the port was already openend by another process.

Krishnan Parthasarathi 2f05aacbf2 Stop profiling on exit of main goroutine (#1670) 
* Stop profiling on exit of main goroutine

Previously, profiling was stopped since Stop() method was called on exit of cli.BeforeFunc.
This lead to profiling to be stopped prematurely.

* Moved profiling switch statement to a separate func
