I am a small business owner, and, out of necessity, use
AIX for one of our CAD workstations. There is no networking, we are simply tied to this platform. I have a project that I am currently working on that required an older version of software to be installed, and in doing so, I accidentally deleted something that prevented me from being able to log in under any profile, including root. So, basically I reinstalled
AIX, (which is OK - better for us, even) but I simply don't know my way around all that well. My questions are basic, so I'll just ask them, and leave it up to the user to either answer directly, or point me to a resource. I need answers in layman's terms, however.
1) I need to increase the size of a file system. In this case, I need to update the oslevel, and I was thinking to put the update tar.gz in its own folder under /tmp. However, it tells me that there is not enough space in that file system. I had thought that I needed to do a "chfs -a size=" in order to accomplish this, but it fails every time, citing "not enough space - delete some files and try again".
2) what is the logic of the directories in Unix? (meaning, what files should I put where?) Is /tmp really a temp directory for things like installs? Or is /usr more appropriate?
3) Can I create a file system on an existing folder? (I think that's what mount point is, but not sure)
I'm really lost on the whole file system thing. Basically, all that I need to do is get a program up and running. Preparing
AIX for installation is the hardest part of the job. I have installed the software dozens of times, but only a ground up install once or twice. Either I've forgotten something, or I've got another problem.
Thank you in advance for any help.
