RE: Disk Array > 2TB

Got it working.

 

Forget about using parted. I just went and make the filesystem straight into the device.

 

mkfs.xfs –L /home -f /dev/sdb

 

that did the job

 

Now df correctly reports 2.6 TB:

 

/dev/sda3             17580928    698932  16881996   4% /

/dev/sda1               256666      8460    234954   4% /boot

none                    517192         0    517192   0% /dev/shm

/dev/sdb             2685296640       528 2685296112   1% /home

 

Filesystem            Size  Used Avail Use% Mounted on

/dev/sda3              17G  687M   17G   5% /

/dev/sda1             251M  8.3M  230M   4% /boot

none                  506M     0  506M   0% /dev/shm

/dev/sdb              2.6T  528K  2.6T   1% /home

 

xfs_info:

Looks like the problem was with parted.

 

 

I’ve got a system with a 3ware 9000 RAID card with 12 250GB SATA drives.

And another one with two 3ware 9000 RAID cards each with 8 250GB SATA drives.

 

Both are running kernel 2.6.8-1 (521) 686smp (Systems are dual Xeon 2Ghz HT).

 

I’ve got no problem with the 2^nd system. Both arrays are 1.75 TB and running fine. However I’d like to join both disks on a single volume.

 

The 1^st system I cannot get the system to recognize the full 2.5 TB.

 

This is my syslog:

However df (and everything else) reports:

What is going wrong?

How can I manage to join both 1.75TB on a single volume? (volume manager doesn’t support above 2TB does it?)

 

Thanks in advance.
