Which would be better (assuming that someone would come to my aid and repair the file on the master)? Also, assuming I have to use the repaired metadata.mfs file, when the server connects to the chunk servers it’ll presumably see more stuff within the chunks that it has in the database – will it then (a) add the extra data from the chunks, (b) fail to start or even worse (c) delete the extra chunks? >> >> I’m happy to provide whatever files are needed, although they do seem to be in the region of 90 megs so will place them on our download portal as requested. >> >> We have 3 chunk servers, 2 share servers (including one metalogger) plus the master and metalogger. >> >> If anyone could help that’ll be grand. >> >> Cheers, >> >> Richard. >> >> This message (and any associated files) is intended only for the use of the individual or entity to which it is addressed and may contain information that is confidential, subject to copyright or constitutes a trade secret.
