I ran into this issue while trying to grow a 1TB filesystem to a 1.5TB filesystem. Example: [snip] 2142948448, 2143324800, 2143701152, 2144077504, 2144453856, 2144830208, 2145206560, 2145582912, 2145959264, 2146335616, 2146711968, 2147088320, 2147464672, -2147126272, -2146749920, -2146373568, -2145997216, -2145620864, -2145244512, -2144868160, -2144491808, -2144115456, -2143739104, -2143362752, -2142986400, -2142610048, -2142233696, [snip] Is this something to worry about as far as file system consistency goes, or is it just a cosmetic problem with the printout? Also, how safe is growfs to use. Are there any known problems? /Daniel Eriksson
