HDD size problem

!! hack-back !! · 09-12-2014, 06:40 AM

i add new hard drives
HDD = 3 TERRA

Code:

root@debian:~# fdisk -l

Disk /dev/sda: 3000.6 GB, 3000592982016 bytes
191 heads, 5 sectors/track, 6136683 cylinders, total 5860533168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0x17b9c867

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1            2048  4294967294  2147482623+  83  Linux

but in df -h its says it is just 2 TERRA

Code:

root@debian:~# df -h

in saidar also the same ... so what is the problem ???

fdisk is used to create and manipulate old-style MBR partition tables, which have a hard partition size limit of 2 Tb.

As you can see from the output form fdisk, the drive reports the number of sectors to be 5860533168, but your partition (/dev/sda1) only covers sectors 2048 - 4294967294. To use the entire drive, you'll have to switch to a GUID partition table (GPT), which also means using a different partitioning tool (like parted).

so i cant use reiserfs ??

!! hack-back !! · 09-12-2014, 07:00 AM

ok i used gdisk+reiserfs

and problem solved
now i have

/dev/sdf1 2.8T 33M 2.8T 1% /cache05

but my next question is , gdisk dont make problem with squid cache ??
thanks.

Squid is an application. It deals with files in a file system, and does not care about partitions or partition types.
