Hi Darren,
Thanks - IBM basically haven't test clearcase with ZFS compression
therefore, they don't support currently. Future may change, as such
my customer cannot use compression. I have asked IBM for roadmap info
to find whether/when it will be supported.
That is FUD generation in my opinion and being overly cautious. The
whole point of the POSIX interfaces to a filesystem is that
applications don't actually care how the filesystem stores their data.
I agree (*). It is very similar to what EMC did some years ago by
officially stating that while ZFS is supported on their disk arrays ZFS
snapshots are not. Even more "funny".
(*) - however compression is not entirely transparent in such a sense
that a reported disk space usage might not be exactly what application
expects. But I'm not saying it is an issue here - I honestly don't know.
