MAINTENANCE BUG about moosefs

[pkonopelko]

Hi @yinjiawind,

I hope you can understand what I mean. Because My english is not good :)

Don't worry! :)

If I shutdown a chunkserver A with maintenance mode on, the chunk under this chunkserver will not be replication.Then, I shutdown another chunkserver B with maintenance mode off, I found that the chunk under chunkserver A will be replication.

It is like that by design - this is a feature, not a bug. It is well-described / documented in "MooseFS 3.0 User's Manual", paragraph 5.3 "Maintenance mode". You can get this manual from the following website: https://moosefs.com/documentation/moosefs-3-0.html.

Please take a look at the quotation (from the manual I mentioned above). It is in bold in the documentation:

Note: Server(s) in maintenance mode must match currently off (disconnected) servers. If they don’t match, all chunks are replicated.

If you have any questions, please don't hesitate to ask!

Best regards,
Peter / MooseFS Team
