What is the issue?

I mounted a JuiceFS filesystem in /root/.ollama in Linux. And run ollama pull llama3.1, I can see llama3.1 with ollama list.

Then I mounted the same filesystem in my mac ~/.ollama. I can see llama3.1 with ollama list. I can also run it with sudo -i. All work well.

And then I create a model writer with Modelfile in Linux. But I cannot see it in my Mac. I find out the new layer of model writer has 600 permission while others are 644:

When I run chmod 644 on these layers manually, it works well and can see writer in ollama list.

What's the backing store for the juicefs? When you mount the juicefs, are there any ACL or umask related options? What's the umask of the ollama server on your linux machine?

grep Umask /proc/$(pidof ollama)/status

The only files Ollama explicitly sets to 0o600 are private key and history files. Everything else should be 0o644. Please check your mount settings and umask as @rick-github suggested

I checked the umask in linux machine @rick-github @mxyng :

Besides, JuiceFS is an open source distributed file system. I do not set ACL or umask when mounting. umask is default 022.

I do not set ACL or umask when mounting. umask is default 022. ``` root@ollama-5cc94c8c4b-t59zr:/# df Filesystem 1K-blocks Used Available Use% Mounted on overlay 123460788 30699160 87515992 26% / tmpfs 65536 0 65536 0% /dev tmpfs 64771088 0 64771088 0% /sys/fs/cgroup JuiceFS:weiwei-test-tke 10995103093488 50492052 10995052601436 1% /root/.ollama /dev/vda3 123460788 30699160 87515992 26% /etc/hosts shm 65536 0 65536 0% /dev/shm tmpfs 128253988 12 128253976 1% /run/secrets/kubernetes.io/serviceaccount tmpfs 64771088 0 64771088 0% /proc/acpi tmpfs 64771088 0 64771088 0% /proc/scsi tmpfs 64771088 0 64771088 0% /sys/firmware root@ollama-5cc94c8c4b-t59zr:/# root@ollama-5cc94c8c4b-t59zr:/# root@ollama-5cc94c8c4b-t59zr:/# cd root@ollama-5cc94c8c4b-t59zr:~# cd .ollama root@ollama-5cc94c8c4b-t59zr:~/.ollama# root@ollama-5cc94c8c4b-t59zr:~/.ollama# root@ollama-5cc94c8c4b-t59zr:~/.ollama# ls history id_ed25519 id_ed25519.pub logs models root@ollama-5cc94c8c4b-t59zr:~/.ollama# root@ollama-5cc94c8c4b-t59zr:~/.ollama# root@ollama-5cc94c8c4b-t59zr:~/.ollama# root@ollama-5cc94c8c4b-t59zr:~/.ollama# ls -alh total 97G drwxrwxrwx 51 root root 49G Aug 15 15:29 . drwx------ 1 root root 4.0K Aug 15 15:04 .. -rw-r--r-- 1 13556 staff 4.0K Aug 15 10:44 ._logs -rw------- 1 root root 33 Aug 15 15:29 history -rw------- 1 root root 387 Aug 13 15:40 id_ed25519 -rw-r--r-- 1 root root 81 Aug 13 15:40 id_ed25519.pub drwxr-xr-x 4 13556 staff 52K Aug 15 10:44 logs drwxr-xr-x 43 root root 49G Aug 13 15:44 models root@ollama-5cc94c8c4b-t59zr:~/.ollama# root@ollama-5cc94c8c4b-t59zr:~/.ollama# root@ollama-5cc94c8c4b-t59zr:~/.ollama# root@ollama-5cc94c8c4b-t59zr:~/.ollama# umask 0022 root@ollama-5cc94c8c4b-t59zr:~/.ollama# root@ollama-5cc94c8c4b-t59zr:~/.ollama# root@ollama-5cc94c8c4b-t59zr:~/.ollama# root@ollama-5cc94c8c4b-t59zr:~/.ollama# cd models/ root@ollama-5cc94c8c4b-t59zr:~/.ollama/models# ls blobs manifests root@ollama-5cc94c8c4b-t59zr:~/.ollama/models# umask 0022 root@ollama-5cc94c8c4b-t59zr:~/.ollama/models# root@ollama-5cc94c8c4b-t59zr:~/.ollama/models# root@ollama-5cc94c8c4b-t59zr:~/.ollama/models# cd blobs/ root@ollama-5cc94c8c4b-t59zr:~/.ollama/models/blobs# umask 0022 root@ollama-5cc94c8c4b-t59zr:~/.ollama/models/blobs# root@ollama-5cc94c8c4b-t59zr:~/.ollama/models/blobs# root@ollama-5cc94c8c4b-t59zr:~/.ollama/models/blobs# ```

Hi @mxyng @rick-github , I have tried this issue without JuiceFS and just use the local file. And it is reproduced. By the way, I use ollama in kubernetes:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: ollama-host
  labels:
    app: ollama-host
spec:
  replicas: 1
  selector:
    matchLabels:
      app: ollama-host
  template:
    metadata:
      labels:
        app: ollama-host
    spec:
      containers:
      - image: ollama/ollama:0.3.5
        env:
        - name: OLLAMA_HOST
          value: "0.0.0.0"
        ports:
        - name: ollama
          containerPort: 11434
        args:
        - "serve"
        name: load
        volumeMounts:
        - mountPath: /root/.ollama
          name: shared-data
      volumes:
      - name: shared-data
        hostPath:
          path: /root/.ollama
          type: DirectoryOrCreate

The ollama in Linux is 0.3.5 and 0.3.6 in Mac

I digged deeper into the code and found that:

When create a new layer, create a temp file which used 0600:

temp, err := os.CreateTemp(blobs, "sha256-")

func CreateTemp(dir, pattern string) (*File, error) {
	if dir == "" {
		dir = TempDir()
	}

	prefix, suffix, err := prefixAndSuffix(pattern)
	if err != nil {
		return nil, &PathError{Op: "createtemp", Path: pattern, Err: err}
	}
	prefix = joinPath(dir, prefix)

	try := 0
	for {
		name := prefix + nextRandom() + suffix
		f, err := OpenFile(name, O_RDWR|O_CREATE|O_EXCL, 0600)
		if IsExist(err) {
			if try++; try < 10000 {
				continue
			}
			return nil, &PathError{Op: "createtemp", Path: prefix + "*" + suffix, Err: ErrExist}
		}
		return f, err
	}
}

And then

os.Rename(temp.Name(), blob)
