Hi! You need to run mfsfilerepair on the files belonging to these chunks. Kind regards Michał Borychowski MooseFS Support Manager _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Gemius S.A. ul.

Subject: [Moosefs-users] Invalid copies of chunks Hi, Last week I swapped two MooseFS servers so that server A previously running mfs-master started running mfs-metalogger and server B previously running mfs-metalogger started running mfs-master. Somehow in the process I ended up with metadata_ml.mfs.back and metadata.mfs.back files that had problems preventing "mfsmetarestore -a" from working correctly. So I went to a previous metadata file and applied changelogs manually. Now I have 29 chunks that have no valid copies and messages like the following appear in my logs: Sep 18 06:15:04 noro mfsmaster[9008]: chunk 000000000568DC8C has only invalid copies (2) - please repair it manually Sep 18 06:15:04 noro mfsmaster[9008]: chunk 000000000568DC8C_00000001 - invalid copy on (128.210.48.90 - ver:00000002) Sep 18 06:15:04 noro mfsmaster[9008]: chunk 000000000568DC8C_00000001 - invalid copy on (128.210.48.88 - ver:00000002) So my question is: how should I proceed to repair these chunks manually as suggested by the log message?
