Description Nithya Balachandran 2015-12-01 06:10:30 UTC

+++ This bug was initially created as a clone of Bug #1286910 +++

Description of problem:
A newly created file on a tiered volume with distributed-disperse cold tier and dist-rep hot tier has EC xattrs set on it even though it exists on a hot tier.

Version-Release number of selected component (if applicable):


How reproducible:
Every time

Steps to Reproduce:
1. Create a distributed-disperse (2x(4+2)) volume and attach a dist-rep hot tier to it
2. Start the volume and FUSE mount it.
3. Create a file on the mount point. Internally, tier first creates a linkto file on the cold tier and then creates the actual data file on the hot tier.
4. Check the xattrs set on the file on the hot tier bricks

Actual results:
The file has EC xattrs set on it

Expected results:
No EC xattrs should be present on files in non-EC subvols

Comment 5 Bhaskarakiran 2015-12-15 09:09:40 UTC

The ec attrs are no longer set on the hot tier which is a dist-rep vol. Marking this as fixed.
