FAQ: LeoFS Limits

Features

Operations

  • When you upgrade your LeoFS, you can NOT change the metadata storage as |KVS| - bitcask or leveldb can be used in LeoFS - used by LeoFS Storage. We recommend users to replace bitcask with leveldb by using |leofs_utils/tools/b2l|.

NFS Support

  • NFS implemantation with LeoFS v1.1 is a subset of NFS v3. Authentication, and Owner/Permission management are NOT covered.
  • The ls command may take too much time when the target directory have lots of child. We're planning to provide better performance with LeoFS v.2.0.
  • If you use LeoFS with NFS, you should set the size of a chunked object in LeoFS to 1MB (1048576Bytes) - large_object.chunked_obj_len = 1048576 (leo_gateway.conf), otherwise the efficiency of disk utilization can be decreased.
  • What are the requirements to run LeoFS with NFS?

    • LeoGateway (NFS Server):
      • We've supporeted the targets Debian 6, Ubuntu-Server 14.04 LTS or Higher and CentOS 6.5/7.0 as LeoFS does, but should work on most linux platforms. In addition, We've confirmed LeoFS with NFS works properly on the latest FreeBSD and SmartOS by using NFS Integration Test Tool.
