Of course you can have character devices. But that has
nothing to do with partitioning. You partition using
fdisk, then use the tool 'raw' to create a device node
that points of the partitions you want to access as
a raw device.



Cheers,
Tink

Following the instruction of here: http://forums11.itrc.hp.com/service/...hreadId=712867 and here: http://www.walkernews.net/2007/07/02...-in-3-minutes/

I have successfully a few partitions of 8GB but it seems that they are in bloc mode not character mode.

I have created a logical volume of 8GB in character mode but I don't know if it's correct created. I see it's in character mode if I create it this way. But if I first create the 8GB partition and then do the mknod -m 0660 /dev/mapper/vg0-spacexx c 4 64 command it tells me that already exist.

[root@herculetest mapper]# lvcreate -L 8096M -n space15 vg0
Logical volume "space15" created
[root@herculetest mapper]# mknod -m 0660 /dev/mapper/vg0-space15 c 4 64
mknod: `/dev/mapper/vg0-space15': File exists
[root@herculetest mapper]#

so therefor i first do mknod -m 0660 /dev/mapper/vg0-space15 c 4 64 and then lvcreate -L 8096M -n space15 vg0

AM I doing right ? And what about the c 4 64 numbers ? I know they are minor and major number, but the minor/major number of what ? If the partition (logical volume) is 8GB what major/minor number should I use ?

Any advice would be great. I prefer profy advice too

)) I think my head was gonna explode, ) I don't know why I did all that. I thought I needed to do them that way. Anyway, it seems that I only need to create the partitions using fdisk and then to bind them to raw devices in dev/raw/myrawcharacterdevices

Did I understand well ?

Hmmm, I understand that I do need to use LVM so I can extend the partitions in case I want to do that.
Second, I need to use symbolic links to access the partitions, this way if the disk has error I can handle the symbolic links better rather than the disk itself. (Informix says it's recommended to use symbolic links).

I don't know about symlinks, but the raw device bit is essential.

Uhmm, I have created the spaces in dev but after reboot the machine they are gone. I have:



[root@herculetest ~]# cd /dev/vg0/
[root@herculetest vg0]# ls
space01 space11 space22 space32 space42 space52 space62 space72 space82
space02 space12 space23 space33 space43 space53 space63 space73 space83
space03 space14 space24 space34 space44 space54 space64 space74 space84
space04 space15 space25 space35 space45 space55 space65 space75 space85
space05 space16 space26 space36 space46 space56 space66 space76 space86
space06 space17 space27 space37 space47 space57 space67 space77 space87
space07 space18 space28 space38 space48 space58 space68 space78 space88
space08 space19 space29 space39 space49 space59 space69 space79 space89
space09 space20 space30 space40 space50 space60 space70 space80 space90
space10 space21 space31 space41 space51 space61 space71 space81 space99
[root@herculetest vg0]#

80 vg of 8GB and 10 of 16GB

Then I use: raw -q /dev/raw/raw01/ /dev/vg0/space01
raw -q /dev/raw/raw02/ /dev/vg0/space02
raw -q /dev/raw/raw0x/ /dev/vg0/space0x etc...

Then I create the symbolic lynks from raw to dev. Problem is that after I reboot the machine the devices in /dev/raw/rawx are gone. Someone told me I need to create them with raw -q / raw -qa in order to "freeze" them but id dosen't work.

Any hints ?
Thanks

Ok, i've found my problem here: http://www.held.org.il/blog/?p=32

I'm gonna do some tests and if it won't work, I will come back here.

I have one question. Reading this article: http://www.held.org.il/blog/?p=32 I don't know what I really should do.

In /etc/udev/rules.d/60-raw.rules

should I write:

Example 1

ACTION=="add",KERNEL=="sdc1",RUN+="/bin/raw /dev/raw/raw01 %N"
ACTION=="add",KERNEL=="sdc1",RUN+="/bin/raw /dev/raw/raw02 %N"
ACTION=="add",KERNEL=="sdc1",RUN+="/bin/raw /dev/raw/raw0x %N"

or

Example 2

ACTION=="add",KERNEL=="space01",RUN+="/bin/raw /dev/raw/raw01 %N"
ACTION=="add",KERNEL=="space02",RUN+="/bin/raw /dev/raw/raw02 %N"
ACTION=="add",KERNEL=="space0x",RUN+="/bin/raw /dev/raw/raw0x %N"

I asked this question because if I write with space0x instead of sdc1 like in example 2, after I reboot the machine I don't longer see them in /dev/raw (it's nothing, it's all gone - after reboot)

If i write like in example 1 after reboot they are still there, which is good but I don't know if it's right to do it like that.


sdc1 is the 850GB volume in which I have created the spaces (80 of 8GB and 10 of 16GB)
