I have set up a RAID5 array using 4 disk partition. All disks are 2TB. When the RAID5 array was initially syncing it was too slow. So I did a
echo 32768 > /sys/block/md2/md/stripe_cache_size
and then it was quiet fast. But still it took a days time to finish syncing. Now I want am doing a
dd if=/dev/zero of=/dev/md2 bs=1024k
onto the RAID5 array and it is like a day over and yet it has not finished. Will this take too much time am I doing some thing wrong.
I have an identical machine with the similar details. But that's quiet faster.
UPDATE: I have added my hdd partitioning details.
