Photos app not working on zfs 2.1.0 / M1 Pro / Monterey

Postby ecbaldwin » Sat Dec 04, 2021 2:57 pm

I loaded my Photos library, which had been on a Big Sur Intel-based system, on my new M1 Pro macbook which shipped with Monterey installed. I am unable to import new photos into the Photos app when the library is on a zfs filesystem.

I tried creating a new Photos library both on and off of the ZFS fs. The non-ZFS library does fine but the ZFS-hosted library will not import a photo. I have been able to reproduce this with a fresh Photos library created on my ZFS filesystem and attempted to import a single photo. It never imports it and never fails with an error message. If I try to import the photo a second time, Photos complains that "Another import session is in progress. Please try again when the current task is complete." It will try again if I quit Photos and restart it. But, it is still the same result. It will not import anything.

I tried off, hfs, and apfs for com.apple.mimic. Normally, I have used hfs.

I am a developer but somewhat unfamiliar with Apple development and troubleshooting file systems. Please help me know what I can do to help troubleshoot this issue.

Thanks,
Carl

Following is some information about my installation (the laptop belongs to Emily but I'm trying to troubleshoot on her behalf).

Hi,

I too noticed that a Photo.Library was not happy when hosted on ZFS (TrueNAS) and accessed via SMB using BigSur. I could import, but I found FaceID completely dead etc etc.

I see your normalisation is set to none. Given you're using the mimic attribute, I'd expect macOS to have FormD (HFS' encoding?) enabled. I think this is in the documentation section but only Lundman would know if it's still needed.

Do you have an photos.app related processings thrashing a core and sitting on 100% all the time? I'm also not sure if these background processes are owned by your uid either and so the group permissions might need to be writable.

Am not in front of my Mac to determine the above myself, but figured I'd reply in hope is points you in the right direction.

Cheers,
tangles

Thanks for your reply.

I have not set this before. My other laptop with a Photos library on ZFS does not have this set. According to ZFSPROPS(8), normalization "cannot be changed after the file system is created." Given that this filesystem is about 500G this will be very difficult to try out. I can try to create an empty filesystem with this property set to formD to see if it makes a difference...

okay, I tried creating a new empty filesystem with normalization=formD. It did not make a difference. I still see the same issue with Photos.

> Do you have an photos.app related processings thrashing a core and sitting on 100% all the time?

Not at all. The CPU usage of Photos processes is very very low when I attempt the import.

> I'm also not sure if these background processes are owned by your uid either and so the group permissions might need to be writable.

I would think that the Photos app would create new libraries with the correct permissions. All of the ones that I have seen are 0755 for directories and 0644 for files. If I attempt to change them, do you think I would have to change the top-level directory and all of the directories in the contained hierarchy?

I tried changing the top level to 0777 and restarting Photos on it. No luck.

mmm,

Seems you've ruled all those possibilities out.

I guess the next step is to run gdb to see what read/write calls are being made on APFS, and then perform the identical test using a ZFS pool to see if there's an issue.

A while ago with O3X 1.9.3 and Photos.app 5 on Catalina, we had a similar problem:
https://github.com/openzfsonosx/zfs/issues/747

Back then, the error messages in the Console did point to an ENOTSUP error (error code 45), which in the end was traced back to the use of vnop_renamex not being implemented by that old ZFS version, but used by Photos during import.

I suggest to check the Photos-related error messages in the console, and then raise an issue in Github.

Thank you for the reply. I will take this to a new issue in github.
