# Generic peer options

# portno_start: Start of port range that will be used by the peer

# portno_end: End of port range that will be used by the peer

# nr_ops: Max number of flying operations. Must be a power of 2.

# log_level: verbosity levels for each xseg peer

#            0 - Error

#            1 - Warnings

#            2 - Info

#            3 - Debug

# Warning: debug level 3 logs A LOT!

# nr_threads: Number of threads of each peer. Currently only blockers supports

# 	      threads with the following tricks:

# 	      a) Threads in file_blocker are I/O threads that block.

# 	      b) Threads in rados_blocker are processing threads. For lock

# 	      congestion reasons, avoid setting them to a value larger than 4.

# file_blocker specific options:

#

# archip_dir: Where archipelago files will reside

# fdcache: Fd cache size

# rados_blocker specific options:

#

# pool: rados pool where objects will reside
