Or do you mean that you run fio from an Administrator command prompt? I was able to run the test successfully using the latest virtiofs driver and fio 3.25. Can you please try to verify if this bug is still reproducible? Thanks, Gal.

Yes, all the pkg version are the same with comment 0, but not reproduce it. Trying to figure out what's wrong with my steps. Hi Gal, Not reproduce on my side, I notice the reporter got a MEMORY-fio.DMP file on comment3, could you please have a check of the dump to see if something useful when you free? http://fileshare.englab.nay.redhat.com/pub/section2/coredump/virtio-win/bz1873088/MEMORY-fio.DMP Thanks Menghuan I guess it may related to queue-size=1024 if not add queue-size=1024 like '-device vhost-user-fs-pci,chardev=char0,tag=myfs ', although I not hit the behavior like comment 0 , I try to access Z:\ to right click 'fio_data.txt', the guest will hang. fio command on Z: fio.exe --name=stress --filename=Z:\\fio_data.txt --ioengine=windowsaio --rw=write --bs=4K --direct=1 --size=1G --iodepth=256 --numjobs=128 (In reply to menli from comment #16) > I guess it may related to queue-size=1024 if not add queue-size=1024 like > '-device vhost-user-fs-pci,chardev=char0,tag=myfs ', although I not hit the > behavior like comment 0 , I try to access Z:\ to right click 'fio_data.txt', > the guest will hang. > > fio command on Z: > > fio.exe --name=stress --filename=Z:\\fio_data.txt --ioengine=windowsaio > --rw=write --bs=4K --direct=1 --size=1G --iodepth=256 --numjobs=128 reproduce it as comment 3, the root cause is: not add queue-size=1024 with device vhost-user-fs-pci (qemu) qemu-kvm: Failed to read from slave.

Add the queue-size parameter in device vhost-user-fs-pci eg: -device vhost-user-fs-pci,queue-size=1024,chardev=char0,tag=myfs Unable to copy large file . https://github.com/virtio-win/kvm-guest-drivers-windows/issues/527 Track this upstream issue here. reproduce steps: 1. start virtiofsd daemon on host #/usr/libexec/virtiofsd --socket-path=/tmp/vhostqemu -o source=/tmp/virtiofs_test -o cache=always 2. boot up win1064 guest with virtiofs device. -m 4G -object memory-backend-file,id=mem,size=4G,mem-path=/dev/shm,share=on -numa node,memdev=mem -chardev socket,id=char0,path=/tmp/vhostqemu -device vhost-user-fs-pci,chardev=char0,tag=myfs \ 3. install winfsp tool and virtiofs driver in guest 4. run virtiofs.exe virtiofs.exe -D c:\virtiofs-log.txt -d -1 5. on host side： dd if=/dev/zero of=bigfile.bin bs=2048M count=1 6. on the guest: Run copy Z:\bigfile.bin . in cmd.exe Actual result: after step4, file not copy successfully. error message: A device attached to the system is not functioning. 0 file(s) copied. pkg: qemu-kvm-5.1.0-17.module+el8.3.1+9213+7ace09c3.x86_64 seabios-bin-1.14.0-1.module+el8.3.0+7638+07cf13d2.noarch kernel-4.18.0-240.el8.x86_64 virtio-win-prewhql-0.1-191.iso additional info: can not reproduce it with '-device vhost-user-fs-pci,queue-size=1024,chardev=char0,tag=myfs ' Hi Gal， The bug ITM is ITM 16 (Mon 2021-02-22)，(2021-02-12~2021-02-17 Chinese Spring festival)， Could we reset ITM to confirm QE have enough time to verify this bug once bug status change to On_QA?

Thanks, Xiaoling Hi Gal, As the ITR is set to 8.5.0, could you also set DTM? Thanks, Xiaoling Removing from 8.5 for now. Will get back to it when done with more relevant bugs. This issue can be resolved with not changing the queue size when doing stress tests. Hi Xiaoling How to properly install fio.exe? I've downloaded MSI from https://bsdio.com/fio/ and installed it. But when I run 'fio.exe' with any command-line arguments it exits immediately and nothing is written to the console.

Hi, Victor, I use fio-3.1 version. I've run fio-3.1 with command-line from original post and it successfully ended: Run status group 0 (all jobs): WRITE: bw=135MiB/s (142MB/s), 1080KiB/s-1081KiB/s (1106kB/s-1107kB/s), io=128GiB (137GB), run=970196-970595msec After that, volume Z: continues to work normally. It seems that one of our previous fixes fixed this issue too. The issue seems to be fixed in virtio-win 0.1.217 Just found out that virtiofs device should be started WITHOUT queue-size=1024 to reproduce. Run fio test on shared dir inside win2022 guest, and WITHOUT queue-size=1024 in qemu cmd line. The result is pass. Test version: virtio-win-prewhql-0.1-221 So set VERIFIED. |
