by customers.

cluster/tier correct promotion cycle calculation

2015-11-07T21:44:38+00:00

This is a backport of 12480

The tier translator should only choose candidate files for promotion
from the most recent cycle, not a multiple of the most recent cycles.
Otherwise user observed behavior can be inconsistent. Remove related
test in tier.t that is subject to race condition.

tier/ctr: CTR DB named lookup heal of cold tier during attach tier

2015-10-11T01:10:18+00:00

Heal hardlink in the db for already existing data in the cold
tier during attach tier. i.e during fix layout do lookup to files
in the cold tier.

CTR xlator on the  brick/server side does db update/insert of the hardlink on a namelookup.
Currently the namedlookup is done synchronous to the fixlayout that is
triggered by attach tier. This is not performant, adding more time to
fixlayout. The performant approach is record the hardlinks on a compressed
datastore and then do the namelookup asynchronously later, giving the ctr db
eventual consistency
