Description Amar Tumballi 2012-04-16 08:35:20 UTC 
Description of problem:
Currently we have a static number of arenas for iobuf allocation. With the current method, the maximum size of buffer allocated through iobuf_get2() is 1MB. But in few cases with CLI (like volume status <VOLNAME> inode, volume profile etc,) we would need bigger buffer to be transferred on wire.


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

CHANGE: http://review.gluster.com/3136 (iobuf: option to provide larger size of buffers) merged in master by Anand Avati (avati)
Comment 2 Raghavendra Bhat 2012-05-24 10:36:36 UTC 
Now larger sized iobufs can be allocated through stdalloc, if the buffer size requested is greater than the maximum available buffer size.
