Dear list,
we are in the process of copying the whole content of a 1.6.7 Lustre FS
to a 1.8.7 Lustre FS. For this I precreated all individual directories
on the new FS to set striping information based on the #bytes/#files
ratio. Then we used a parallel rsync to copy all directories over. All
of this worked fine. Now, on the old FS the user data consumed 63 TB
while on the new FS 'df -h' reports only 56 TB as used. I'm sure we
copied all dirs and all rsyncs finished successfully.
Is this difference expected if one moves from 1.6->1.8? Or did I miss
something?
Regards, Michael
