Parâmetros de alocação de file systems

Em sistemas Solaris, caso se deseje saber com quais parâmetros determinado file system foi alocado, basta emitir o comando

  # mkfs -m <device

Por exemplo:

  # mkfs -m /dev/dsk/c1t0d0s7
  mkfs -F ufs -o nsect=80,ntrack=19,bsize=8192,fragsize=1024,cgsize=16,free=10,
  rps=90,nbpi=2048,opt=t,apc=0,gap=0,nrpos=8,maxcontig=7 /dev/dsk/c1t0d0s7 2090000

O comando mkfs (make filesystem) na maioria dos casos não é utilizado diretamente. O comando utilizado para criar filesystems normalmente é o newfs, que é uma interface para o comando mkfs, que provê alguns valores default para a alocação

Estes parâmetros podem ser modificados de acordo com a característica do filesystem. Este tópico será abordado em dicas futuras.

McAfee-Question : Is Windows a Virus ?

No, Windows is not a Virus. Here's what does that...

1) They replicate quickly - Okay, Windows does that. 2) Viruses use up valuable system resources, slowing down the system as they do so - Okay, Windows does that. 3) Viruses will, from time to time, trash your hard disk - Okay, Windows does that too. 4) Viruses are usualy carried, unknown to the user, along with valuable programs and systems. Sigh... Windows does that, too. 5) Viruses will occasionally make the user suspect their system is too slow (see 2) and the user will buy new hardware to improve speed. Yup, that's with Windows too.

Until now it seems that Windows is a Virus, but there are fundamental diferences :

Viruses are well supported by their authors; they are running on most systems; their program code is fast, compact and efficient; and they tend to become more sophistcated as they mature. So Windows is not a virus. It's a bug.
