anolis8-5.10-14-rc1内核也存在同样的问题，且xfstests测试套下多个用例都由同一原因导致用例失败，和fio包升级相关，相关用例如下： ext4/301，ext4/302，ext4/303，ext4/304，generic/299，generic/300， 以ext4/301为例，日志如下： # cat /tmp/tone/run/xfstests/results//ext4/301.full Discarding device blocks: done Creating filesystem with 93150720 4k blocks and 23289856 inodes Filesystem UUID: 2ad049e7-c24d-4092-ac6f-192685cef3ba Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968 Allocating group tables: done Writing inode tables: done Creating journal (262144 blocks): done Writing superblocks and filesystem accounting information: done # Common e4defrag regression tests [global] ioengine=ioe_e4defrag iodepth=1 directory=/fs/nvme0n1p2 filesize=126684979200 size=999G buffered=0 fadvise_hint=0 ################################# # Test1 # Defragment file while other task does direct io # Continious sequential defrag activity [defrag-4k] ioengine=e4defrag iodepth=1 bs=128k donorname=test1.def filename=test1 inplace=0 rw=write numjobs=4 runtime=30*1 time_based # Verifier [aio-dio-verifier] ioengine=libaio iodepth=128*1 numjobs=1 verify=crc32c-intel verify_fatal=1 verify_dump=1 verify_backlog=1024 verify_async=1 verifysort=1 direct=1 bs=64k rw=randwrite filename=test1 runtime=30*1 time_based # /usr/bin/fio /tmp/2706909.fio fio: engine libaio not loadable fio: failed to load engine defrag-4k: (g=0): rw=write, bs=(R) 128KiB-128KiB, (W) 128KiB-128KiB, (T) 128KiB-128KiB, ioengine=e4defrag, iodepth=1 ...
