inode64 mount option added after data exists

inode64 mount option added after data exists

[Ivan.Novick]

Hi all,

Quick question about the inode64 mount option.

Is it safe to add this mount option to a file system that was already created and wrote lots of data without it.

Will it still work as intended in this case (use 64 bit inodes)?

Cheers,
Ivan

Yes.

Yes, for newly created inodes and data.

Cheers,

Dave.

When you have the existing files/dirs, would it help to take an existing 
dir "$path/old", create a new dir "$path/new", and then do

cd $path/old
find . -type f -exec "ln {}  ../new/" \;
rm *
mv ../new/* .

to get the inodes created in the new space? This could be necessary in 
case the first 1TB is full, and no more inodes can be created. I'm just 
not sure if that would be enough.
