Generally seen with cached diskpools and files that grow with compression...
TSM pre-allocates based on listed size by the OS and in the case of cached
diskpools, frees that amount of cached space to take the file.
If you have compression yes and compressalways yes AND if a file grows
during compression, then you will see the failure such as listed below...
To avoid such situations use "compression yes" and "compressalways no" and
that will generally prevent this problem.
