Today, if we perform an xfs_growfs which adds allocation groups, mp->m_maxagi is not properly updated when the growfs is complete. Therefore inodes will continue to be allocated only in the AGs which existed prior to the growfs, and the new space won't be utilized. This is because of this path in xfs_growfs_data_private(): xfs_growfs_data_private xfs_initialize_perag(mp, nagcount, &nagimax); if (mp->m_flags & XFS_MOUNT_32BITINODES) index = xfs_set_inode32(mp); else index = xfs_set_inode64(mp); if (maxagi) *maxagi = index; where xfs_set_inode* iterates over the (old) agcount in mp->m_sb.sb_agblocks, which has not yet been updated in the growfs path. So "index" will be returned based on the old agcount, not the new one, and new AGs are not available for inode allocation. Fix this by explicitly passing the proper AG count (which xfs_initialize_perag() already has) down another level, so that xfs_set_inode* can make the proper decision about acceptable AGs for inode allocation in the potentially newly-added AGs. This has been broken since 3.7, when these two xfs_set_inode* functions were added in commit 2d2194f. Prior to that, we looped over "agcount" not sb_agblocks in these calculations.
