[Lustre-discuss] Understanding lfs output

[Mag Gam]

My departments Lustre's lfs df -i looks like this

UUID                    Inodes     IUsed     IFree IUse% Mounted on
xfs001-MDT0000_UUID   82565322  19073586  63491736   23%

/xfs/engine1/xfs001[OST:3]

filesystem summary:   82565322  19073586  63491736   23% /xfs/engine1/xfs001


Is it safe to say, "
My MDT has "19073586" 19 million inodes free? or should I consider.

However, when I check my inode count on my mds using tune2fs it reports this.
Inode count:              524288000
Free inodes:              505214414

Am I missing something?

TIA
