Do you mean the cyrus.cache file in those folders? Is a > reconstruct enough to recreate them or doesn't happen automatically. I had a filesystem which had one directory that was totally corrupted inside due to random gremlins (not sure when it happened, but with terabytes of storage, these things do happen occasionally, even with RAID you still get occasional errors on the wire - the research on this really quite disturbing!) I moved it out somewhere else and recreated the meta directory then reconstructed the mailbox. Worked fine. You do need to reconstruct and if you can copy the cyrus.index back in then you'll find that no information (flags, etc) should be lost. I failed over to the replica and took the filesystem offline and ran a full fsck (reiserfsck in this case) which only found the one error on that folder. Ran with rebuild-tree to remove it from the tree (it wasn't deleteable otherwise) and all was good. And yeah - for pretty much anything involving the cache file, reconstruct is your friend. Everything in the cache file is copies of data in the original messages, so reconstruct can rebuild it precisely.
