Thread: Partitions & Filesystems help

hi, i'm aix background used volume groups containg logivcal voumes filesystems on top. installed ubuntu 11.04 desktop defaults onto pc , want create filesystems. "df -m" shows me looks fs /dev/sda1 has of disk.

code:

bradders@ubuntu-desktop:~$ df -m filesystem           1m-blocks      used available use% mounted on /dev/sda1                36848      4867     30110  14% / none                       368         1       368   1% /dev none                       375         1       374   1% /dev/shm none                       375         1       375   1% /var/run none                       375         0       375   0% /var/lock

an "ls /dev/sd*" shows me available devices.

code:

bradders@ubuntu-desktop:~$ ls /dev/sd* /dev/sda  /dev/sda1  /dev/sda2  /dev/sda5

not sure these thought i'd try , create fs on /dev/sda1 (assumedly) fs, makes sense

code:

bradders@ubuntu-desktop:~$ sudo mkfs.ext3 -l /newfs /dev/sda1 [sudo] password bradders:  mke2fs 1.41.14 (22-dec-2010) /dev/sda1 mounted; not make filesystem here!

so thought i'd try making fs on /dev/sda following;

code:

bradders@ubuntu-desktop:~$ sudo mkfs.ext3 -l /newfs /dev/sda mke2fs 1.41.14 (22-dec-2010) /dev/sda entire device, not 1 partition! proceed anyway? (y,n)

i guess i'm being pretty dumb here. wanted have (in aix terms) whole disk 1 vg, create new filesystems on vg required, allocating necessary space each one. how acheive here? tia

i don't know aix or volume groups sounds me want 1 extended partition many logical partitions in it. tool gparted can it. have unmount partition have run gparted livecd.
