Topic: How can I check out the allocation of the two HDs?

[TeNeCo]

Could you please explain how SME hast allocated the HDs during installation?

I have two hds of around 20 GB in the PC but the available space is not the expected 40GB but 20. Has SME arranged the disks in a kind of RAID1?

The following results i have:

Code: [Select]


[root@sme ~]# fdisk -l /dev/hda

Disk /dev/hda: 20.5 GB, 20520493056 bytes
240 heads, 63 sectors/track, 2650 cylinders
Units = cylinders of 15120 * 512 = 7741440 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1          14      105808+  fd  Linux raid autodetect
/dev/hda2              15        2650    19928160   fd  Linux raid autodetect
[root@sme ~]# fdisk -l /dev/hdc
[root@sme ~]# fdisk -l /dev/hdb

Disk /dev/hdb: 20.0 GB, 20020396032 bytes
255 heads, 63 sectors/track, 2434 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hdb1   *           1          13      104391   fd  Linux raid autodetect
/dev/hdb2              14        2434    19446682+  fd  Linux raid autodetect
[root@sme ~]#

Is that really a RAID so that the system can stand the failing of one of the disks?

Log in as admin and look in the console menu re disk management

Alternatively use this command
cat /proc/mdstat


Personalities : [raid1]
md1 : active raid1 hda1[0] hdc1[1]
      104320 blocks [2/2] [UU]

md2 : active raid1 hda2[0] hdc2[1]
      80308864 blocks [2/2] [UU]

You have both your drives on the same controller channel.
It's better if you connect one to Channel1 (Primary master) & the other to Channel2 (Secondary master) in case the drive controller fails in one channel only.
eg hda & hdc

Yes. Please thoroughly read the manual:

When and how is a failing of one of the disks reported?

e-mail to admin@<your domain>

It will also show up on the disk management screen of the console.
