![]() Doing that makes it possible to move files between your Mac’s files system and the file system used by the operating system you run as a virtual machine or the cloud storage service you are using. macFUSE bridges that gap – it provides a means for your Mac to access those other file systems. However, not every OS uses the same file system as macOS, and so your Mac doesn’t know how to use the file system used by Windows or other OSes. And your Mac can do the same with files stored on drives it’s connected to, thanks to a file system with strict rules. We can find books easily because we know how the filing system works. Think of a library, where the books are arranged in alphabetical order and by category. They control how files are created, stored, written to, and read from. File systems are one of the most basic building blocks on which operating systems are built. ![]() To understand what macFUSE is, we need to talk about file systems. But what is it, and why is it there? And how do you uninstall it if you no longer need it? Read on to find out. It was likely installed by the virtualization or cloud storage software. It’s nothing to worry about, even if you don’t remember installing it yourself. If you’ve ever installed virtualization software on your Mac or used a tool to allow you to mount cloud-storage drives on your desktop, you may have noticed a pane in System Preferences called macFUSE. But to help you do it all by yourself, we’ve gathered our best ideas and solutions below.įeatures described in this article refer to the MacPaw site version of CleanMyMac X. GitHub if you can verify cat opens the file O_RDONLY.So here’s a tip for you: Download CleanMyMac to quickly solve some of the issues mentioned in this article.So this looks like a bug in FUSE-T at first glance and it might be worth creating a bug here Issues Assuming it is the same on macOS (I don't know if you can use strace but there is bound to be a similar tool) then the O_RDONLY is being translated by FUSE-T into an O_RDWR which is causing the problem. On Linux if I strace cat file.txt I can see cat opens the file with O_RDONLY as it should. 5 09:40:09 DEBUG : /file1.txt: Read: ofst=0, fh=0x0ĥ 09:40:09 ERROR : file1.txt: WriteFileHandle: ReadAt: Can't read and write to file without -vfs-cache-mode >= minimalĥ 09:40:09 DEBUG : /file1.txt: >Read: n=-1ĥ 09:40:09 DEBUG : /file1.txt: Read: ofst=0, fh=0x0ĥ 09:40:09 DEBUG : /file1.txt: Flush: fh=0x0ĥ 09:40:09 DEBUG : file1.txt: WriteFileHandle.Flush unwritten handle, writing 0 bytes to avoid race conditionsĥ 09:40:09 ERROR : file1.txt: WriteFileHandle: Can't open for write without O_TRUNC on existing file without -vfs-cache-mode >= writesĥ 09:40:09 DEBUG : /file1.txt: >Flush: errc=-1 Which then fails when the write only handle is read from. WIthout -vfs-cache-mode we can only read or write not both. We now try to open it with read/write - rclone assumes you want to write here and creates a write file handle. The file1.txt exists 5 09:40:09 DEBUG : /file1.txt: Getattr: fh=0xFFFFFFFFFFFFFFFFĥ 09:40:09 DEBUG : /file1.txt: >Getattr: errc=0 It is included.įrom your first example this appears to be the problem It includes it The rclone config contents with secrets removed. Local for testing with mount The command you were trying to run (eg rclone copy /tmp remote:tmp) Which cloud storage system are you using? (eg Google Drive) The following WORKS: $ rclone mount src/ mnt/ -vv -vfs-cache-mode minimal -log-file minimal_mount.logĪnd the following FAILS (with a different error) $ rclone mount src/ mnt/ -vv -vfs-cache-mode minimal -read-only -log-file minimal_readonly_mount.logĪny vfs cache < full doesn't make sense with read only so I try that too $ rclone mount src/ mnt/ -vv -vfs-cache-mode full -read-only -log-file full_readonly_mount.logįull_readonly_mount.log (12.9 KB) Run the command 'rclone version' and share the full output of the command. When I try to cat a file in the mount, it FAILS: $ cat file1.txt ![]() rclone mount src/ mnt/ -vv -log-file reg_mount.log I created a simple local directory of a few files to try to mount and read as a test. With FUSE-T, if I mount with anything other than miminal cache fails. I decided to try FUSE-T instead of the "regular" FUSE. What is the problem you are having with rclone?
