I deployed a fastdfs file cluster on five servers, assigned as follows:
tracker1:117.48.231.77
tracker2:117.48.231.99
[group1]
117.48.231.94
117.48.231.88
[group2]
117.48.231.84
you can upload files to the storage of two group.
but the problem now is that if you send a file to [group1], the cluster will only transfer the file to 117.48.231.88, while the file of 117.48.231.94 will not be sent to Synchronize, and the cluster will not send the file to 117.48.231.94. However, according to the file upload mechanism of fastdfs, the storage in [group1] should have a chance to be selected, and the files stored in the two machines should automatically Synchronize after the file is uploaded.
related logs are as follows:
