Hi all,
I hope you can help with a couple of questions below as we're wanting to reclaim some white space from our filers but I've got various bits of info from other sources so would like a bit of clarification;
1 - Using the tool I keep reading you can release xx% of your free space, so does this mean if I think I can reclaim 25% of my total storage of 4TB, then can I run the command with the -y 25 and reclaim 1TB or will it reclaim 256GB (i.e. 25% of 1TB)? Can this reclamation process keep being done until I get close (not all I understand) to reclaiming the white space?
2 - I have taken the warnings of not trying to reclaim 100% of free space because you can fill up your storage during the process so can I tell vmkfstools to use an external HDD/Storage area to run the reclamation? i.e. old server with several large HDDs all formatted to required protocol.
As for everything else recommended or advised we are ready to go, we're all just a bit unsure of how often this can be done, how close to the full size we can go and very importantly the last part above - Can we use an external source to do the work of the white space reclamation, i.e. like a page file swap system?
Many thanks for any help you can provide,
Daiman
