Bug ID: 1733935
Summary: Open fd heal should filter O_APPEND/O_EXCL
Product: GlusterFS
Version: mainline
Status: NEW
Component: disperse
Assignee: bugs at gluster.org

Description of problem:
Problem:
when a file needs to be re-opened O_APPEND and O_EXCL
flags are not filtered in EC.
- O_APPEND should be filtered because EC doesn't send O_APPEND below EC for
open to make sure writes happen on the individual fragments instead of at
the
end of the file.
- O_EXCL should be filtered because shd could have created the file so even
without O_EXCL open should succeed.
Fix:
Filter out these two flags in reopen.
