Hi,
I came across a situation where I had to increase a filesystem that was 100% full and received this error:
[root]/tmp[common]:chfs -a size=+5000M /tmp
0516-634 lquerypv: /tmp directory does not have enough space,
delete some files and try again.
0516-788 extendlv: Unable to extend logical volume.
Is there a way to override this if I am unable to delete files in the file system to create some space?
I assume /tmp will be simply needed for this operation. If the files can not be deleted, can you move/copy them to another place or just compress them?
Else I would boot box in maintenance mode and try it then, if the current workload/situation allows it.
I suspect chfs uses /tmp to operate, so if it is full you cannot use the command.
Clear out /tmp (and see why it's full because that is the root of the problem) then try again.
You may not need to increase the size if you work out why it is full / what causes the problem...
