[ZODB-Dev] FileStorage database unrecoverable?

[Greg Czajkowski]

Hi Tim
Yes, I have installed 2.2.2 

BTW. To report on some other issues, after
fsrecovering and packing the database I get
POSKeyError exceptions from time to time, pack
unavailable exceptions, and appropriate already
packing exceptions. Im not worried about the packing
errors as I have "designed" them in. I just hope the
POS errors don't affect any loss of data.

Pack unavailable
