Anis Elleuch 0fddf3fe17 Avoid creating tmp directories under .minio/tmp/ to facilitate cleaning (#2187) 2016-07-12 09:38:45 -07:00
Harshavardhana ca1b1921c4 XL: Implement ignore errors. (#2136) 
Each metadata ops have a list of errors which can be
ignored, this is essentially needed when

  - disks are not found
  - disks are found but cannot be accessed (permission denied)
  - disks are there but fresh disks were added

This is needed since we don't have healing code in place where
it would have healed the fresh disks added.

Fixes #2072
