When this occurs the following call trace is printed on the console, XFS: Assertion failed: (bip->bli_flags & XFS_BLI_STALE) || (xfs_blft_from_flags(&bip->__bli_format) > XFS_BLFT_UNKNOWN_BUF && xfs_blft_from_flags(&bip->__bli_format) < XFS_BLFT_MAX_BUF), file: fs/xfs/xfs_buf_item.c, line: 331 Call Trace: xfs_buf_item_format+0x632/0x680 ? kmem_alloc_large+0x29/0x90 ? kmem_alloc+0x70/0x120 ? xfs_log_commit_cil+0x132/0x940 xfs_log_commit_cil+0x26f/0x940 ? xfs_buf_item_init+0x1ad/0x240 ? xfs_growfs_rt_alloc+0x1fc/0x280 __xfs_trans_commit+0xac/0x370 xfs_growfs_rt_alloc+0x1fc/0x280 xfs_growfs_rt+0x1a0/0x5e0 xfs_file_ioctl+0x3fd/0xc70 ? selinux_file_ioctl+0x174/0x220 ksys_ioctl+0x87/0xc0 __x64_sys_ioctl+0x16/0x20 do_syscall_64+0x3e/0x70 entry_SYSCALL_64_after_hwframe+0x44/0xa9 The kernel patch "xfs: Set xfs_buf type flag when growing summary/bitmap files" is required to fix this issue.
