[Moosefs-users] Invalid copies of chunks

[Steve W. <st...@pu...>]

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?

Thanks!

Steve
