OK, so everything works as expected on local machine.
Then you share over Samba
A network client accessing it, can read, but not write ?

[hspantera]

Yes . On local machine 100%. Local share can write but not read.. strange . I can see the files . For example I see all my Mkv movies but when I open gives me an error. Don’t play.

[hspantera]

Sorry. On network client that this happens. Can’t read but can write.

[lundman]

Yeah, I'll dig into it tomorrow.
If you are bored, run "FileSpy" as Administrator http://www.zezula.net/en/tools/filespy.html and change it to monitor your ZFS drive, then make the client write problem happen, could be it will give hints.

[hspantera]

No.. no problem in write. Only read.

this is my local zigs drive.

This is my network share on another windows 11 pc on same network

I can see all files and folders . Can write to share but can’t read. If I try to read from voc it show me this error.

very strange. Because I can access.. see what’s in there.. write to it. But can’t read files.

[lundman]

error when dragging to desktop or somewhere to copy?

[hspantera]

Yes.. won’t let me read too

[lundman]

ok thanks. I'll check what FileSpy says tomorrow

[hspantera]

FileSpy info.zip

here is filespy when i try to acess video file on client share

[lundman]

Hmm interesting - it's certainly trying a few times, and something makes it unhappy.

[hspantera]

very strange. but it happens on both windows clients with windows 11 pro workstation installed. same error on both.

[lundman]

Refuse a lock, and
the open-by-id seems to fail.
Could be either of those two, or of course, something completely different

[hspantera]

i have 2 windows clients on same network and they both do exactly the same thing. can see whats inside, can write to the share but cant read or do nothing with existing files.

[hspantera]

Another strange thing that happens

open a folder

then select mkv file

give me an error on vlc can’t read

and if I open again same folder it shows empty. No mkv file. But I go to the original pc and open folder and it’s there. Only on client don’t show. It does this with all files I try to open on client share. Open file. Gives error. Open folder again and it’s empty. But the file still existed on original pc.

[hspantera]

But after a while I open the folder and it shows the file again. But if I try to play gives error and desapears again.

[hspantera]

this is my zpool.

[lundman]

yes it is just that it uses something unexpected to verify the file is there, and ZFS replies incorrectly, so it removes it. Small files, like .nfo/.sfv also fails to read? In case it is a filesize thing

[hspantera]

It opens a small winrar file of file spy for example. But .srt file don’t show on client.
I copy 5 srt files to the original zpool folder and on client don’t show the files.

[hspantera]

.txt file don’t show too.

[lundman]

OK, not a filesize thing. I didn't it was, but worth ruling out.

[hspantera]

Hi. Have a question not related with this problem. I extended my raidz2 with one new hard drive. Has you can see in picture is resizing. It says it will take 4 days. My question is:
Can I export the pool and change all drives to new system and import the pool and continue to resizing from where it lefted when I export it? Thanks

[lundman]

ZFS it supposed to let you do that, and it will continue to resilver. Haven't tried it but the core is the same.

[hspantera]

Ok. I will do it.. after I import in new system I have to execute any command? Or it starts resizing automatically?

[lundman]

Should just start, afaik

[hspantera]

Yes.. worked perfectly.. started resizing automatically. Thanks. What about the bug of share? Did you see anything? Thanks.

[lundman]

OK, so smb works here, but one side is Win10 - so it could be that Win11 has changed something. But in the FileSpy it clearly tries FileFsObjectIdInformation multiple times, so I have implemented that - perhaps it will help.

Can you try:

OpenZFSOnWindows-debug-2.2.3rc2-2-geb5def3b01.exe

from releases.

[hspantera]

Installed and still has same problem..

[lundman]

Rats - can you do a new FileSpy - so we can see how it behaves now?

[hspantera]

FileSpylog.zip

here t is.

[lundman]

Thanks. Looks pretty good, does retry a bunch of times, which sort of suggests it's not happy about something, even if we now have implemented one of the calls.
IOCTL_MOUNTDEV_QUERY_DEVICE_NAME still fail, but I think it is supposed to.
I will have to set up a Win11 client as well, and give it a whirl myself.

[hspantera]

It’s very strange.. it should work. But always same error trying to opening video files.. or some file.. it says “can’t open location file” but I can have access to files.. very strange..

[lundman]

So you can read/write/copy, but not play video?

[hspantera]

More strange is that I open shared zigs folder on other windows 11 pro workstation and I can copy from the shared folder to the local pc that I’m accessing.. just don’t read . But I can copy from shares folder??? How strange is that???

[hspantera]

Yes

[lundman]

oh, you said you can't read, so I've been testing with dragging files from smb to desktop. That reads the files. I can try playing with VLC as well then, make sure they start.

[hspantera]

I can drag and drop too.. but opening with vlc gives error.. or any player ..

[hspantera]

But another problem.. I have a folder with 10 mkt files.. I drag and drop one.. everything works fine.. but if I go to the other mkv file in that folder gives me an error of “the item it’s not located in this folder anymore” and I can’t xopy any more files from that folder. But if I go to another folder it lets me always copy one file and if I try the second one it always give me that error. Do this in every folders..

[hspantera]

Hello.. still no fix for mapped openzfs file not reading files?

[lundman]

I have not yet found a way to replicate this locally - it just works (unless I misunderstand what the problem is). Trying to think of other ways this can be added. Do you have space for VMs?

[hspantera]

Did you test on windows 11 pro workstation? Or just windows 11 pro?

[lundman]

My VM is https://developer.microsoft.com/en-us/windows/downloads/virtual-machines/

Point me to a version that you know fails?

[hspantera]

This is my windows https://www.microsoft.com/en-us/windows/business/windows-11-pro-workstations

[sskras]

It's not a VM neither an .iso file. The nearest thing I found was the .iso:
https://www.minitool.com/news/download-windows-11-pro-for-workstations.html#download-windows-11-pro-for-workstations-42952

[hspantera]

Im not using vm. Using the version installed on pc. Windows 11 pro workstation.

[hspantera]

Maybe that’s the problem. You can’t replicate windows 11 pro workstation on VM.

Have you tried to replicate that in a VM, and the issue disappeared? That would help testing.

Hi.. I have a problem.. I have this pool

And it’s not phisycal drive 1 in it.
I want to make another zpool but it say that physical disk1 is already a pool enter. But it isn’t. I only have one pool and physical disk 1 it’s not in that pool. How I remove physical disc1 from pool member? Because it don’t belong to any pool.


Can you help me? Because when I try to make a new pool it doesn’t show option to select physical disc 1. And physical disc one don’t belong to the already existing pool. So physical disc one said it’s a pool member but it’s not from any pool. Can I remove it? So I can add it to new pool?

IMO this is a separate issue.

I suggest to copy source of your message (by clicking Edit and then copying all the editable text) and create a new topic in the Discussions tab using the same text.

This issue is about file I/O failures on the mapped drive.

[lundman]

Perhaps zpool labelclear on physicaldrive1 is needed? Or create it without the gui.

[hspantera]

Sorry. But I’m kind of new here and it was just a question. Solved the problem. Didn’t started my pool and all drives where free. So I don’t use the ones that already where assigned to my already created pool and it worked. And I have one more question. You are being so helpful. I’m trying to update napp-it but on newer version I get this error. Can’t do anything. Always give me this error everytime . Think you can help me?

It show me all options but always that error. And I read somewhere that you where realeasing a web gui . It’s already out?

[lundman]

For nappit we might need to invite napp-it's @gea but it is concerning the reddit user is deleted, and the windows.pdf is now 404. Wonder what happened there.

[hspantera]

But old version works ok. Don’t exist other web gui based?

[hspantera]

Sorry to bother again. To update to the rc4 version I have to rename this file to what?

rename …\openzfs.sys to for example …\teste.sys?

[hspantera]

Can’t just uninstall rc3 and install rc4?

[hspantera]

Hi. One question. I have a folder on my zfs pool that I click and it won’t open. And if I try to delete it won’t delete. Any chance of tell me what I can do? It refuses to open and to delete. Only that folder.. I have 3000 folders. Only that one don’t open. If it’s error of the pool what I can do to solve this? Thanks.

[lundman]

Renaming? Best would be to look in cbuf after it failed, but that is difficult if you aren't setup to develop.

[hspantera]

It lets me rename the file. But still don’t let me delete or open folder. Is my pool in danger?

[lundman]

I wouldn't have thought so, I thought maybe it had a name it couldn't translate. I assume you have rebooted to see if that helps.

[hspantera]

Already rebooted. It’s the same. There is some option to force delete?

[hspantera]

I think I’m going to have to find another solution for my media. Using openzfs on windows since the release of stable version and here is my thoughts. Pros- very fast writes. Very fast reads. Cons- with the time it’s going to corrupt a file here Another there Until the pool it’s compromised. Still very buggy on the options like shares and how it delete files. It’s a great filesystem but for windows it’s yet very unreliable. I think it have potential to get the best filesystem in the future but for now it’s very dangerous having a 70terabite storage on openzfs. In any moment it will corrupt on file or a folder and you can’t do nothing about that other than destroy pool and create a new one. Other issue for normal users like me it’s the commands to execute openzfs. Napp-it simplifies a little bit but still not a filesystem that it’s straight forward. Thanks for all support and I will looking for new releases and hope one day it becomes native like NTFS.
