Out of disk space on AIX
“Help, old SCSI disks for my 90s pSeries cost a fortune and things keep failing because we’re out of space. I keep pruning but it’s not enough. df shows I’m out of room everywhere.”
Never fear, you probably have loads of space. A default install allocates about half the hard disk. Run “lsvg” to find some free “PPs” you can dynamically add to volumes (like partitions, but logical rather than linear slices of the disk). Then “chfs -a size=+1G /opt” will sort you out.
I felt so silly after discovering that today. A bit like the day I found I could roll halfway through a TL upgrade because it mirrors your disks and keeps half the space aside for fancy tricks like that.
