I had message internal error in download/upload queue
I moved file node.db4o to backup directory - and now everything
works. But i lost all my download/upload keys. Anybody knows if
there is any chance to get them back? just keys or filenames...
i tried some tools for db4o database but don't work. is it
encrypted or something?
This (node.db4o corruption) should be a known bug. (I mentioned it
here on June 12th). It's kind of hard to duplicate -- for me it
usually occurs when I have more than an average amount of
data/items in my queues and my node.db4o is unusually large (200+
MB vs. a more normal 50MB).
It is caused by either flaky hardware or bugs in db4o itself. Either
way there is little we can do about it apart from regular automated
backups. We will implement that eventually.
I will have to humbly disagree :P. I'm running on top of Software Raid5
(and LVM), so any disk-io bugs (hardware or otherwise) would have been
handled gracefully. (And my smartd daemon would have picked up on it
too.)
Does RAID5 always check the checksums on any read? Mirroring e.g. certainly
does not.
And I don't think a corruption bug this serious would still be in the
wild in something as big and popular as db4o :P.
(*cough*.)
You'd be surprised. :|
