Thank you Artem.
Do you know if the lustre filesystem can work properly with these errors
and without enable this feature?
Regards.

Hello Fernando,
The option is enabled by command:
tune2fs -O large_dir <ldiskfs_partition>
BUT, this feature is still in testing, so I do not suggest use it in
production.
Also, current Lustre FS e2fsprogs don’t support this feature. Now it available
only for EXT4 since E2fsprogs 1.44.0 (March 7, 2018) and linux 4.13.
I hope this feature will be enabled in WC e2fsprogs which will be released with
Lustre FS 2.12.
Best regards,
Artem Blagodarenko.

Dear all.
We have a lustre system with combined mds + mdt ldiskfs and several osts with
zfs and ldiskfs.
I have these errors in our mds server log:
LDISKFS-fs warning (device dm-4): ldiskfs_dx_add_entry:2618: inode 30544460:
comm mdt01_047: index 2: reach max htree level 2

How can I enable the large directory feature in our lustre filesystem to solve
these errors?
I can't see references to this feature in the lustre documentation. Is it
related with the LU-1365?
Regards.
