Mounting a 1.5 Tb Hard Drive but showing only 138 Gb: where's the catch?

NiceLittleRabbit · 12-13-2009, 02:22 PM

Hello,

I am pretty newbie to Linux. I have a Debian server up and running and I have tried to add an extra hard drive for backup purposes.

I have created a new (and only) primary partition on my new 1.5 Tb hard drive and set it to type 83 (ext3), all of this using fsdisk. I have written the whole lot onto the hard drive.

When I check the partition table (by running again fsdisk) it tells me there's only one primary partition, type ext3 and 1.5 Tb.

#fdisk /dev/sdd | p

Disk /dev/sdd: 1500.3 GB, 1500301910016 bytes
255 heads, 63 sectors/track, 182401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xde08ed32

Device Boot Start End Blocks Id System
/dev/sdd1 1 182401 1465136001 83 Linux

Then I have created a /backup folder (by typing '#mkdir /backup' as root)

I mount /dev/sdd1 onto /backup:

#mount /dev/sdd1 /backup

I then type

#df -h

And I get:

/dev/sdd1 138G 138G 0 100% /backup

And indeed, there are 138Gb used and I cannot write anything else on the hard drive (Disk is full).

Summarizing, I purchased, installed and formatted a 1.5Tb hard drive, but when mounted only 138Gb are visible/available.

Can anyone help me, please?

Thanks in advance,

Sorry, but no one's able to guess details about your system without you help.
Distro/kernel version/etc?

I believe you may have a BIOS problem. Is this an older motherboard?

You might try using the search function and searching for 137GB. You might want to look through this thread, as well: http://www.linuxquestions.org/questi...ighlight=137gb

Hello,

My motherboard is 1 year old, ASUS P5KPL-AM

Distro: Debian Lenny

Kernel: 2.6.30 handmade (but from the debian kernel .config, did not change much really just wanted to have the hand on it)

I already have several RAID partitions of 500Mb mounted, but all simple partitions I want to mount are 138Gb independent of their real capacity:

Filesystem Size Used Avail Use% Mounted on
/dev/sda1 138G 5.5G 126G 5% /
tmpfs 501M 8.0K 501M 1% /lib/init/rw
udev 10M 760K 9.3M 8% /dev
tmpfs 501M 0 501M 0% /dev/shm
/dev/sdc1 138G 2.8G 128G 3% /save
/dev/md2 459G 390G 46G 90% /home3
/dev/md0 780G 324G 417G 44% /home

/dev/sda1 and /dev/sdc1 are 150Gb partitions, of which only 138Gb are showing.

Please let me know if you need any additional information

Thanks

Hello,

I have checked the BIOS and did not find any HPA restriction.

Hello Worm5252,

Should the quote help me solve this problem?

Thanks

Quakeboy02 · 12-15-2009, 10:52 PM

Did you cut and paste that, or did you type it in manually? This line makes no sense:

Code:

sdd: sdb1 sdb2 sdb3 sdb4

I don't understand how /dev/sdd can have partitions /dev/sdb1 etc. I would think they would be /dev/sdd1, etc. Also, I see that you have a 780G /home so the kernel has no problem with it. Have you tried making the first partition on /dev/sdd something small, say 20GB and then putting the rest on the second partition?

Just trying to get a handle out of what you have and why.

NiceLittleRabbit · 12-21-2009, 05:16 PM

Hello,

Finally the stupidest thing had happened: had forgotten to format the HD

Sorry about that. It certainly does not explain however why it says sdd: sdb1 sdb2 sdb3 sdb4

I did not make those up, just a copy and paste ... I'll keep investigating

Thanks
