Title: Disk Size
Post by: riggers5 on January 16, 2005, 11:25:40 AM

I have migrated SME6.01-1 from Raid1 40GB HDDs to raid1 80GB HDD.  after running raidmonitor and veiwing mdstat it shows:
Personalities : [raid1]
read_ahead 1024 sectors
md2 : active raid1 hda3[0] hdc3[1]
      522048 blocks [2/2] [UU]
     
md1 : active raid1 hda2[0] hdc2[1]
      77417152 blocks [2/2] [UU]
     
md0 : active raid1 hda1[0] hdc1[1]
      208704 blocks [2/2] [UU]
     
unused devices: <none>

but running df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/md1               36G   13G   22G  36% /
/dev/md0               99M   14M   79M  15% /boot
none                  250M     0  250M   0% /dev/shm

So is the system using the full 80GB or not?

Filesystem Size Used Avail Use% Mounted on
/dev/md1 36G 13G 22G 36% /
/dev/md0 99M 14M 79M 15% /boot

99M total boot = 14M used + 79M free (plus rounding & raid overhead)
36GB total data = 13G used + 22G free (plus rounding & raid overhead)

How did you migrate?  If you used Ghost or similar you may not have expanded the partitions to fill the physical disk capacity.

Originally I tried doing a backup and restore onto a fresh installation, afetr a number or failed attempts I gave up on that and tried ghosting, which worked well apart from not resizing the partitions as you said.  I then tried mondo archive which did resize the partitions, but none of the run level 7 services would start, so I was unable to connect to restor the /home backup I had created (as per how to).  I then tried ghost again, ghosting each individual partition to the partitions mondo archive had made (/boot 200MB, /swp 512MB / remainder).

Am i misreading the mdstat file or is that showing the larger partition sizes compared to df?

is it possible to resize the partition after ghosting?

.. easy to do under Windows but not sure about Linux ext3 partitions (on a RAID!).

I would imagine it is possible but I can't quite recall the package I was thinking of ... if my memory returns I will let you know.
