No, there isn't any "new version".
This is the error message I had:

chunk_readcrc: file:/mnt/chunks/chunk0/chunk//01/chunk_00000000006639E9_00000001.mfs
- read error: Success (errno=0)

but /mnt/chunks/chunk0/chunk//01/chunk_00000000006639E9_00000001.mfs
doesn't exist in any version. Probably it was replicated with a new
chunk name

# find /mnt/chunks/ -name 'chunk_00000000006639E9_*'
#


> If there is lot of other things to do (replication of other undergoal chunks for example) then yes. Such chunk should be treated in the same way as any other undergoal chunk. Did you check the GOAL/VC table on the Info tab in mfs.cgi? Did you have "yellow" chunks? If not then maybe system created valid copy, but didn't remove damaged chunk.

Honestly, i've not looked at CGI page because I was seeing in the log
multipe "chunk_readcrc", thus, CRC mismatch was still detected.
If CRC is detected, I think that MooseFS still haven't replicated
(fixing the CRC) the chunk.

This is a test cluster, no other operations where running.
