System I/O error on reconstruct after nuking cyrus.* files

[Rick Kunkel]

Hello all,

Is this normal?  I swear to have seen people suggesting trashing cyrus.* 
files and running reconstruct on the user, but I'm having no luck.  In 
this case, that was not what was attempted, but the end result is the 
same.  The cyrus.* files are gone.  See for yourself...

reconstruct: System I/O error

I have tried about ever possible combination of things I can think of, to 
no effect.  Somewhere I saw touching new files with the same names and 
permissions, but that just generates an "Invalid Mailbox" error.  Also, if 
I move cache files from another directory in there and run reconstruct, 
everything works, but the existing messages in the directory can't be 
seen.  Does anyone have any suggestions?

Thanks,
