I see that your disks are not of equal size - I have seen one other report of problems with the RAID-5 driver (in reaidreconf - not the kernel RAID-5 driver) related to disks of different sizes. > Just before the conversion has finished or some times even at > beginning I get and error "raid5_map_global_to_local: disk 0 block ou= t > of range: 488098 (487840) gblock =3D 1464296" or similar and raidreco= nf > aborts. Yep - very similar to that other report. > I'll add below script of the program running as well the used raidt= abs > and listings of partitiontables.

You can run "gprof raidreconf" and see which routines take up the most CPU time :) --=20 =2E............................................................... : jakob@unthought.net : And I see the elder races, : :.........................: putrid forms of man : : Jakob =D8stergaard : See him rise and claim the earth, : : OZ9ABN : his downfall is at hand. : :.........................:............{Konkhra}...............: - To unsubscribe from this list: send the line "unsubscribe linux-raid" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
