[lustre-discuss] Lustre Size Variation after formatiing

[Mannthey, Keith]

MDT with ldiskfs has a large amount of it total space pre-allocated for inodes.  Standard tools don’t see this as “free space” and is very normal for free space to seem odd.

I would suggest you track free inodes on an Ldiskfs MDT as it is more meaningful metric for most users.

Thanks,
Keith

Could you share the command line used to do the actual formatting?

Dear Team,

I am trying install lustre from the pre built RPMs and after installation i am facing LUN size huge variation.

Please find my infra details as below:-

1) CentOS 7.4
2) Lustre version 2.11
3) MDT LUN Size is 6.5 TB (RAID 10) and after formatting using lustre we are getting the size as 3.9 TB, when formatted using XFS is showing accurate.

Thanks,
ANS.
