Fastdfs Unable to upload file problem description and Solutions

Today, the development of feedback, found that there are two groups in the Fastdfs can not upload files, simply tested the following:

Fdfs_upload_file/etc/fdfs/storage.conf/root/1.jpg

will return to me n00~n02,n04,n06~n10 but lack of n03,n05

Through Fdfs_monitor and monitoring (23000 ports) are no problem, so specifically compared to the difference between N02 and n03,n05:

Because at that time when learning Fastdfs, vaguely remember Fastdfs there is a default reserved space for a configuration option, locate this is found in the tracker configuration file Reserved_storage_space = 50G this option, It is important to note that this is the space reserved by total, not the space reserved by the individual path.

You can also see the description of this option in the configuration file:

# Reserved storage space for system or other applications.

# If the free (available) space of any stoarge server in

# A group <= reserved_storage_space,

# no file can be uploaded to the this group.

Solution:

1. Modify the tracker configuration file to reduce the parameters: Reserved_storage_space = 20G (can only be resolved temporarily, not a permanent solution)

2. Expansion, new storage server group, space expansion
