** Also affects: ubuntu Importance: Undecided Status: New ** Tags removed: intel-kernel-19.04 ** Tags added: intel-kernel-19.10 ** Description changed: Description There is a call trace during fio testing of IMSM RAID 5 array. Call trace is attached. How reproducible: always (after few hours of fio testing) Steps to Reproduce: 1. Create IMSM RAID5 with 4 disks: mdadm -C /dev/md/imsm0 -n 4 -e imsm /dev/nvme0n1 /dev/nvme1n1 /dev/nvme2n1 /dev/nvme3n1 mdadm -C /dev/md126 /dev/md/imsm0 -n4 -l 5 -c 64 -f 2. Increase number of RAID5 threads: echo 4 > /sys/block/md126/md/group_thread_cnt 3. Trigger fio: fio --time_based --name="fio_check=16=16=4kb=100" --filename=/dev/md126 --rw=randrw --rwmixwrite=100 --bs=4kb --direct=1 --do_verify=0 --eta=never --iodepth=16 --ioengine=libaio --runtime=600 --ramp_time=600 --refill_buffers --numjobs=16 --group_reporting --randrepeat=0 --thread --unified_rw_reporting=1 --cpus_allowed=2-17 --cpus_allowed_policy=split --disable_lat=1 --disable_slat=1 --disable_bw=1 --stonewall --norandommap --minimal --output=results_16_16_4kb_100.log Target Kernel: TBD - Target Release: 19.04 + Target Release: 19.10 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1801282 Title: [VROC]Call trace during IO on IMSM RAID 5 (fio performance check) To manage notifications about this bug go to: https://bugs.launchpad.net/intel/+bug/1801282/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
