    Description

      This ticket is for tracking enabling the wide striping feature ("-O large_xattr") by default for newly-formatted ldiskfs filesystems.

      Without this option, the maximum OST stripe count will be limited to 160 stripes, instead of the advertised maximum of 2000 stripes.

            The ea_inode feature has been enabled by default in testing via patch https://review.whamcloud.com/28425 "LU-9846 lod: Add overstriping support" since 2019-06-01.

            Just for future reference, enabling the ea_inode feature caused some OOM issues in the VMs used for review testing for versions 1-7 of the 4315 patch, because ldiskfs is returning ocd_max_easize = 1MB by default.

            The upstream e2fsprogs now has support for the ea_inode feature, with some minor (but backward compatible) changes to the on-disk format, so this feature is much less risky to enable.

            Closing this until such a time that LU-908 is resolved.

            Patch at http://review.whamcloud.com/4315.

            Note that one minor concern about enabling this by default is that this feature is not included in the upstream ext4/e2fsprogs yet due to LU-908, so I'd prefer to limit this to only systems that absolutely need this feature.
