RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description xiagao 2020-08-27 10:39:46 UTC 
Description of problem:
Boot up vm with virtio-fs device,do fio testing in the shared file system(Z:), after a while fio tesing failed and can't access Z:

Version-Release number of selected component (if applicable):
qemu-kvm-5.1.0-2.module+el8.3.0+7652+b30e6901.x86_64
kernel-4.18.0-232.el8.x86_64
seabios-1.14.0-1.module+el8.3.0+7638+07cf13d2.x86_64
virtio-win-prewhql-189

How reproducible:
100%

Steps to Reproduce:
1. start virtiofsd daemon on host
#/usr/libexec/virtiofsd --socket-path=/tmp/vhostqemu2 -o source=/home/virtiofs_test3 -o cache=none -d

2. boot up win1032 guest with virtiofs device.
-m 4096 \
-object memory-backend-file,id=mem,size=4G,mem-path=/dev/shm112,share=on \
-numa node,memdev=mem \
-chardev socket,id=char0,path=/tmp/vhostqemu2 \
-device vhost-user-fs-pci,chardev=char0,tag=myfs2,bus=pci.7 \

3. install winfsp tool and virtiofs driver in guest
4. copy winfsp-x86.dll(winfsp program provided) and virtiofs.exe to the same dir
5. run virtiofs.exe in the dir.
virtiofs.exe -d -1 -D -
6. open computer in guest and see a new virtioFS(z:) volume is shown.
7. run fio testing 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

Actual results:
1) fio testing stopped after a while.
2) could not open Z:

Expected results:
fio testing success on shared dir.

Additional info:
1. virtiofsd log on host

Which version of fio is it? Where do I download it?

I got the following results:

Gal, do you have admin permission to run fio command? Seems it need admin permission.

Yes, I have admin privileges. Or do you mean that you run fio from an Administrator command prompt?
Comment 10 Gal Hammer 2020-12-29 13:28:10 UTC 
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.
Comment 11 menli@redhat.com 2021-01-06 12:47:33 UTC 
Test on following build, not reproduce this issue.

Do you mean with the same virtio-fs driver version?

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.
Comment 15 menli@redhat.com 2021-01-14 02:22:17 UTC 
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?

Comment 16 menli@redhat.com 2021-01-14 11:37:19 UTC 
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

To where do you add the queue-size parameter?

AFAIK the memory dump doesn't include anything useful. I download the check again.

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.

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
Menghuan

sorry, the code freeze date is 02-17, so if the bug can fixed before freeze date ,ITM 16 should be okay.

The root cause for this bug shoud be 'queue-size=1024', without this parameter， will hit the issue described above.
-device vhost-user-fs-pci,chardev=char0,tag=myfs

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.
Comment 38 Viktor Prutyanov 2022-04-21 16:14:44 UTC 
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.
Comment 39 Viktor Prutyanov 2022-04-23 19:59:34 UTC 
The issue seems to be fixed in virtio-win 0.1.217
Comment 40 Viktor Prutyanov 2022-04-23 20:03:19 UTC 
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.
