[lustre-discuss] lfs_migrate issue

[Ahmed Fahmy]

Good day,

I have been trying to migrate the data one of the OSTs in my lustre file system before removing the OST.

I have used the following command:

lfs find --obd lustre-OST0001_UUID /lustre | lfs_migrate -sy

I believe the data has been copied correctly.


However, when I check the size of the directories that has been participating in the migration process, I notice that the size has increased with a 3 or 4 GB increase, even after removing the OST.

I am not sure what is the reason for this issue and how I can return those directories to their original sizes.

I am using lustre 2.10.1.

Any help would be appreciated.
