I guess GFS2 has some caching problems then..

This means that dovecot.index file said that transaction log is  
synced up to offset 284, but when Dovecot was trying read the  
dovecot.index.log file, it found data only up to offset 104. So  
either GFS2 said that the file ended at offset 104, or it decided to  
return old data from cache. I guess it's the latter, because the log  
file reads are done without locking.

Probably the easiest way is to just put the index files into local disk.
