Description Krutika Dhananjay 2015-10-08 06:13:30 UTC
+++ This bug was initially created as a clone of Bug #1252263 +++

Description of problem:

Same as subject. Not performing inode_forget()s on individual shards also will lead to memory leaks, given that FUSE (possibly GFAPI as well) have no knowledge of inodes associated with individual shards. It is for sharding translator to clean up these resources.

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

How reproducible:

Steps to Reproduce:

Actual results:

In addition to the above, shard translator will also need to regulate memory consumption by inode_t objects for individual shards of different sharded files, so that too many inode_t objects in memory don't result in the client process getting OOM-killed.
