[Monotone-devel] how to recover damaged database?

[Kelly F. Hickel]

While testing the import of our CVS repo, the machine was rebooted.  After the reboot, when I tried to continue importing, I received the message below.  In this instance, I could just start over, but it raises the question of what would happen if we were using this for real? We’d have a daily backup of course, but if this turned out to be unrecoverable, that would be “bad” (I realize that I have no reason to believe it’s unrecoverable, just wondering)….

 

Thanks,

Kelly

mtn: this is almost certainly a bug in monotone.

mtn: discarding debug log, because I have nowhere to write it
