Storage Formatierung

2013-02-08 @ Disk, Filesystems

Öfters mal gesehen

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1              63  3907029167  1953514552+  83  Linux
Partition 1 does not start on physical sector boundary.

mit parted kann man das dann richten:

Falsch:

(parted) mkpart primary 32.3kb 2000GB
Warning: The resulting partition is not properly aligned for best performance.

Richtig: Bei Blocksize von 512bytes * 2048 Blöcke:

echo $((512*2048))
select /dev/sdd
rm 1
mkpart primary 1048576b 2000GB

Wenns fertig ist sieht das so aus:


## fdisk -l
