On my iphone SE I have, in the files app, a connection to an smb server. This always allowed my to place places on that server.
Since updating to ios 18 however, the folders on this server are read only, preventing me from creating new files.
The server itself, as well as the credentials, are not changed.
Is there a solution for this?
Thank you.
iPhone SE, iOS 18
I seem to have found a workaround. Try this at your own risk and make backups of configfiles you change! Make sure you know what you are doing.
Somewhere in your config on your server (perhaps in /etc/samba/smb.conf) there is probably a
[global]
section.
In that section, see if there is a line that starts with
vfs objects =
If it is not, add this line:
vfs objects = streams_xattr
If it is, add
streams_xattr
to that line
Restart samba service
Reconnect your ios device to the smb server

Just installed iOS 18.1.1 and it still isn’t fixed!!! Why is this going unnoticed? Surely many businesses have been affected by this!!
Not fixed in ios 18.0.1
Same problem on iPad Air — this seems to be a Files app issue. No problems copying files from iPad to SMB server with File Browser app.
I'm having the same issue on iOS 18
Same here, iPhone SE connecting to QNAP over SMB.
Same here, iPhone 12 connection to FRITZ.NAS SMB.
I can confirm that this issue occurs with iPadOS 18.0 (22A3354) when attempting to connect to any SMB server (tested with Windows 10, Windows 11, and Windows Server 2016). For security reasons, I cannot share the full capture file, but as shown, the tree connect response grants full access, whereas file openings are restricted to read-only.
what worked for you?
Today I called the AVM Hotline and they gave me a precious hint:
if you access your drive via the Safari Interface of your iPhone, then you will be able to write/modify. It works for me, see screenshot. Also they are working on a fix.
Me too. Also, smb://192.168.x.x not opening in shortcuts. Don’t want to use Linux. I want to access to my shared folders with windows. Btw from MacOs I can write. Only iOS read only
All of my samba folders on WD PR4100 are vfs objects = catia fruit streams_xattr
and they are all read only.
Consistent with other solutions, I've remedied this using the streams_xattr VFS Object.
My QNAP ships with a limited set of modules, but I've confirmed that the following commands work in my scenario:
setcfg Samba "VFS Objects" "streams_xattr"
setcfg global "VFS Objects" streams_xattr
setcfg global "VFS Objects" streams_xattr -f /etc/config/smb.conf
This third command doesn't persist across a Samba service restart (or QNAP restart) but takes effect immediately; the share must then be reconnected on all affected devices.
If you tend to restart your QNAP often or would struggle to replicate this as needed, this is probably worth dumping in a script or cron job.
then try here:
you‘ll be directed to your USB overview; click then on your drive, the NAS overview shall open
This works!!! Huge Thanks!!!
files/folders on smb server read only since ios 18
