OpenZFS on OS X

hi all

been using openzfs on Mac mini since 2011 til now with Mac mini m2 pro .....for me super lucky I have rarely have any major issues with my setup .

till recently I realise I can not change any folder icon like I do on my MBP ....I wanted to use the free osx app (add folder icon app) to add an icon on each of my pic folder which I have a missive collection 5 - 6T( few hundreds sub folders) . I wanted to have a thumb view for me easily to find my pic album.

I tested, and it only happen on the zfs file system . I also have a 2T nvme permanent attached to my mini and the folder icon there can be change.

I also use the traditional method (copy pic/png and paste on the the "get info" icon ) but same works on the nvme(formatted using APFS and my local ssd (APFS ofocz). but NOT on the zfs file system .

when I did the copy n paste to change the icon it create a system file Icon? with 0 byte . I check all zfs system folder ownership/permission and I have full access to it .

I can't find any where on the google peoples mentioned this issues ( not on zfs file system)

can any point me to the right direction ?


many thx in advance !

am using zfs-macOS-2.2.2 release with latest macOS Sonoma

i believe changing the folder icon is done using extended attributes, if you're looking for keywords. there have been discussions about issues with extended attributes before on the forums, somewhere

just do some search on this forum by key work "icon" "xattr" ....

yea they mentioned successfully change icons but

A they are based on old Intel Mac so maybe the code are different then my m2 ?
B they are discussing other issues which I have no idea what they talked about ;D sorry

however from what I read from their discussion I figure I try xattr -l my zfsdatatank and it's show :

user@m2pro ~ % xattr -s /Volumes/myzfs/zfs/
org.netatalk.Metadata
org.netatalk.has-Extended-Attributes
com.apple.FinderInfo

also zfs get xattr myzfs/zfs

user@m3pro ~ % zfs get xattr myzfs/zfs
NAME PROPERTY VALUE SOURCE
myzfs/zfs xattr on default

whatever that mean ?

so what should I suppose to change the com.apple.FinderInfo or something ? if anyone know how pls enlighten me

I also wanted to state that ...this 4x disk zfs raidz1 are created by truenas scale and imported into this MacOS. I have been doing that for the last 3 radiz1 and I never had any issues with it ( or I fix it by look at internet )
And .....on smb share of that truenas I also CAN do the folder changing (pic as thumbview)! on zfs file system.

many thx !
