Topic: is my software RAID ok?

[kyle coburn]

after installing raidmonitor a few weeks ago, i decided to do a check just to make sure it is working.
[root@KC-Web root]# /usr/local/bin/raidmonitor -v
and nothing happens...
so i did
[root@KC-Web root]# /usr/local/bin/raidmonitor -i
and then again i do
[root@KC-Web root]# /usr/local/bin/raidmonitor -v
still nothing i just get a new prompt


when i view mdstat i get this:
Personalities : [raid1]
read_ahead 1024 sectors
md2 : active raid1 sdb1[0] sda1[1] 263040 blocks [2/2] [UU]
md0 : active raid1 sdb6[1] sdb5[0] 11136 blocks [2/2] [UU]
md1 : active raid1 sdb7[1] sda5[0] 909184 blocks [2/2] [UU]
unused devices:

the reason i am checking is becuse in phpsysinfo i get this for my filesystem config:
                                      Free            USED           Size
/       ext2 /dev/md1  67% 246.24 MB   583.27 MB   873.90 MB
/boot ext2 /dev/md0  55% 4.15 MB      5.83 MB      10.53 MB
Totals :                    67% 250.39 MB  589.10 MB    884.42 MB

i have 2 identical SEAGATE ST32550N 2.1gb drives installed with software raid from the first day, why does it show that i only have 884mb total, i should have 2.1gb total. RIGHT??


Thanks for your time

What does this say:

fdisk -l /dev/sda
fdisk -l /dev/sdb

Are you taking full advantage of your available space?  IE, are the partitions using 100%

My only other guess would be the BIOS has incorrectly identified these drives, or your SCSI card is having issues supporting drives over 1024MB.

Is this an older system?

here is the output from these compands, thanks for your help:

[root@KC-Web root]# fdisk -l /dev/sda

It seems the partitions are hosed..both disks should have the same partition structure.  I notice /dev/sbd has two additional RAID partitions, that aren't being used.  When you installed E-Smith, did anything go arwy?  Were your disks clean?  Did you create any additional partitions?

[kyle coburn]

no, nothing went wrong disks were wiped clean and formated. and checked I choose software raid, i guess i will just cope for now untill the next major SME upgrade i will try a fresh install. everything works fine. ill check my bios settings before my next install.  Will making a boot disk work with the next version of the SME server say 6.0? Will it restore my current settings? All i would have to do then is backup my ibay and primary data correct?


thanks for everyones advise
