Let me start by saying that I read absolutely everything regarding this topic (using google), and there is definitely not enough information, especially about the more complicated case when you use 2TB drives and need to create multiple raid5 arrays.
I am using this "manual" http://buffalo.nas-central.org/wiki/Ter ... _and_RAID5
So what I did so far:
installed 4 x 2tb drives, re-flashed with telnet access itimpi.
created several partitions:
sda3 - primary, 650GB size. 650 because I figured with a limit of single filesystem being 2TB, raid 5 on 4 partitions 650GB each will give me 1950GB so slightly below the limit, correct me if I am wrong
sda4 - extended partition, in full remaining size
sda5 - partition created "on extended partition", again 650GB size
sda6 - partition created "on extended partition", again 650GB size
sda7 - partition created "on extended partition", full remaining size
this is how my partition table looks like:
/dev/sda1 1 48 385528+ 83 Linux
/dev/sda2 49 65 136552+ 82 Linux swap
/dev/sda3 66 72930 585280081 83 Linux
/dev/sda4 72930 243201 1367709839 5 Extended
/dev/sda5 72930 155793 665605047+ 83 Linux
/dev/sda6 155794 238657 665605048+ 83 Linux
/dev/sda7 238658 243201 36499648+ 83 Linux
Installed busybox, but after that I am stuck. In manual it says (copy&paste)
"and you will see which nodes are already existing for disc sda. sda6 will probably not exist, so add it. The 755 is the bitmask for the access rights, just enter the same as the other partitions. The same for the 3. The ?? must be replaced by a number matching the highest you find for partitions on this disc increased by 1. Example: sda1 has the number 21, sda2 has 22, sda5 should have 25 and for sda6 you must enter 26.
mknod -m 755 /dev/sda6 b 3 ??"
I am not native english speaker but this above is a gibberish I cannot understand, saying more I do not understand the sense of doing the mknod command in this context. Is this because the created partitions on the extended partition are not visible as devices in my /dev directory?
root@TS-TGLE24:/# ls -al /dev/sda*
brwxr-xr-x 1 root root 8, 0 Jan 30 2003 /dev/sda
brwxr-xr-x 1 root root 8, 1 Jan 30 2003 /dev/sda1
brwxr-xr-x 1 root root 8, 2 Jan 30 2003 /dev/sda2
brwxr-xr-x 1 root root 8, 3 Jan 30 2003 /dev/sda3
brwxr-xr-x 1 root root 8, 4 Jan 30 2003 /dev/sda4
brwxr-xr-x 1 root root 8, 5 Jan 30 2003 /dev/sda5
Anyway I am writing here to confirm that what I did so far is correct and ask what should I use for "??" in the example "mknod" command above
thanks for all support
