[lustre-discuss] Error with project quotas on 2.10.6

[Mohr Jr, Richard Frank (Rick Mohr)]

I just recently installed a new Lustre 2.10.6 file system using the RPMS from /public/lustre/lustre-2.10.6-ib/MOFED-4.5-1.0.1.0/el7.6.1810/patchless-ldiskfs-server.  (I had already built and installed MOFED-4.5-1.0.1.0, and I installed e2fsprogs-1.44.5.wc1-0.el7).  I was able to format the MDT and I enabled project quotas using “tune2fs -O project <mdt_device>”.  However, when I tried to mount the MDT, it failed with the following error message in dmesg: 

LDISKFS-fs warning (device dm-3): ldiskfs_enable_quotas:5614: Failed to enable quota tracking (type=2, err=-16). Please run e2fsck to fix.

After a little trial and error, I discovered that if I disabled project quotas then the MDT mounts fine.  From my searching, this looks like the same problem as LU-9418, but that issue claims to have been fixed back in 2017.  Does anyone know if this is a new issue?  Or did I miss something in the documentation?
