How to convert a thick file system to thin in celerra
Hello,
We are running out of pool space on our Celerra (DART 6.0.43-1). There are few file systems which are getting full and I have to expand them very frequently, but now we are running out of pool space. Among other options to reclaim space, I was looking at the file systems which are under utilized in our box, but are thick provisioned. Is there any way we can enable virtual provisioning on them and reclaim the space from these file systems to give back to the pool?
Thanks,
Kaustuv

I just tried this in my lab and while it does let you convert a thick filesystem to a thin one, the underlying pool does not get the space back. Basically it will be thin moving forward, so I can advertise a larger filesystem that will only take up the new space as needed, but you can't go back and reclaim the thick space you already have provisioned.

No - not for already fully provisioned file system
Create a new fs and copy the content using client tools

Hello Rainer,
Greetings!
We have similar situation like Deykau's case. As your suggested to create a new fs and copy the content using client tools.
May I know the best client tools for NFS share and CIFS share.
Thank you in advance
Kind regards,
dynamox

You can use this for more details about the tool suggested by Dynamox :

Thanks for the reply!
Could you please share an example or syntax for these emcopy and rsync as I'm not aware of these tools before.
Best regards,

As always – reading the manual / readme and understanding which options make sense for your environment makes more sense than just using settings that you don’t know what they do
The emcopy.zip actually includes a emcopy.txt that lists all the options
