I have an AIX server and its root partition says 100% space used. There was only 2 GB initially allocated. I want to increase its size using chfs. I want to know is this is safe to increase the size or it may have some issues?

  • There's no way to answer that question without understanding the underlying volume group definition, physical volume sizes and space, logical volume config, etc. That's why @JeffSchaller is asking for more information. In one sense, the answer is yes it's safe, AIX will try and will fail gracefully if there isn't sufficient space or there are other constraints, and so it's safe to try. But to know if it will succeed before you execute the command, you (and hence we) need to know more detail. – EightBitTony Nov 28 '17 at 13:18
  • Also note that a true root logical volume on AIX (i.e. the '/' filesystem) shouldn't be very big, and it's usually an indication of a problem elsewhere (core dumps are a good example). – EightBitTony Nov 28 '17 at 13:20
