Krishnan Parthasarathi bef72f26db xl: Make locking more granular for PutObjectPart requests (#2168) 2016-07-11 17:24:49 -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

Krishnan Parthasarathi 285a94d2c0 Ignored errors in cleanup in commitXLMetadata (#2044) 
Deletion of tmp files where xl metadata was saved before the commit
operation doesn't change the error returned to the caller. So, it is to
be ignored.

Harshavardhana 50d25ca94a XL: Change AppendFile() to return only error (#1932) 
AppendFile ensures that it appends the entire buffer. Returns
an error otherwise, this patch removes the necessity for the
caller to look for 'n' return on short writes.
