Hey again. So it seems that data-b is always fine (well at least three times in a row) and data-old-a always gives errors.
including e.g: bad extent [3067663679488, 3067663695872), type mismatch with chunk bad extent [3067663876096, 3067663892480), type mismatch with chunk bad extent [3067663892480, 3067663908864), type mismatch with chunk bad extent [3067663908864, 3067663925248), type mismatch with chunk bad extent [3067669348352, 3067669364736), type mismatch with chunk bad extent [3067669430272, 3067669446656), type mismatch with chunk bad extent [3067669659648, 3067669676032), type mismatch with chunk bad extent [3067669790720, 3067669807104), type mismatch with chunk bad extent [3067669807104, 3067669823488), type mismatch with chunk bad extent [3067669823488, 3067669839872), type mismatch with chunk bad extent [3067669872640, 3067669889024), type mismatch with chunk bad extent [3067669921792, 3067669938176), type mismatch with chunk bad extent [3067671805952, 3067671822336), type mismatch with chunk I've started debugging (everything as before) with: (gdb) break cmds-check.c:4387 Breakpoint 1 at 0x42cf2b: file cmds-check.c, line 4387.
