Re: [gpfsug-discuss] Biggest file that will fit inside an inode? 3876!

No, but (I think) TCT uses some of the EA space in the inode to indicate that the data is in the cloud tier. And yes, it does copy the data blocks in the inode to the clod tier if you migrate it. Bob Oesterlin Sr Storage Engineer, Nuance HPC Grid From:

Would you tier an in-inode file to the cloud? I mean, I wouldn't tier an in-inode file out to tape? Simon From: gpfsug-discuss-boun...@spectrumscale.org [gpfsug-discuss-boun...@spectrumscale.org] on behalf of Oesterlin, Robert

[gpfsug-discuss] License question

2016-10-03 Thread Simon Thompson (Research Computing - IT Services)
