Incorrect number of file hard links
It requires a reboot into single user mode to repair and will return if fish is used. Another user has confirmed the issue. If I build and install from macports this does not occur, but I've noticed that they are at version 2.
If I download the pre-build app from fishshell. I am happy to further research and debug the problem if anyone has tips on how to tackle this. I am a developer but it's been awhile since I've worked in the c world. I can reproduce this using similar methodology: Install yosemite, xcode, homebrew etc but not fish: no disk errors brew install fish 2. Following the same process with fish 2. Then the errors return. We don't remove it on shutdown I can't remember the semantics right now, but it may not be safe to do so.
Right there with you. Thought I had hardware issues, replaced my SSD, ran memory tests but everything checked out. I think zanchey may be on to something. It is. Among other things, it prevents you from performing many common disk-modifying operations, such as installing Boot Camp or resizing partitions. Some of these can be performed within system recovery, but importantly, some can't if for instance you are using CoreStorage volumes , because as soon as you fix the errors and reboot into normal mode, errors return.
I myself experienced this hard link error on my macbook air, at the time i didn't tie it into fish and since I've repaired it has shown up again. Both have ssd drives, so if fish is responsible for this it isn't a sure thing to happen. Im also running 2.

I too have isolated this down to fish, version 2. Command Line Developer Tools, Homebrew and bash. The results are consistent between having Core Storage enabled and reverting the volume to its native type. On a side note, having this in config. Thanks for this investigation niclasgelin.

My laptop died; I should be able to take a closer look next week when the replacement arrives. No problem ridiculousfish. After spending a couple of hours suspecting the SSD being up for early retirement I wanted to at least share my findings. But it keeps coming back even when removing fish.
It's driving me crazy.

This happens on a FileVault enabled disk and running Yosemite. You could do the same while waiting for a fix. I'm running version 2. Any downside?

It would need testing on Ubuntu, as the Yama security module does its best to block it - I did try that initially and I'm pretty sure it doesn't work. Good idea zanchey. I'd love to find some simple repro steps for filling a bug against OS X. It looks like that particular command doesn't trigger it, but a similar one might. I'll file a bug. This doesn't seem to reproduce with ordinary files, e. Filed at bugreporter. I'd be happy to roll a 2.
If there's no old versions installed then the link never gets touched. I hate the idea of leaving a minor version with a serious bug like this - it means that when we regress issues we'll corrupt our filesystem. Maybe the thing to do is to commit a simple fix to 2. I'm not sure I understand correctly though: the bug happens in 2.
Should I downgrade to 2. Or is it fixed in master and should I build from master? The problem is solved in the Master branch? Is there a specific set of commits with the fixes? Super User is a question and answer site for computer enthusiasts and power users. It only takes a minute to sign up. I'm on OSX, have a folder '4' and two links pointing to it:.
When I follow 'Current' in folder it leads to a completely different location the path I copied all the stuff from. I'd like 'Current' to point on the folder '4' at the new location. If you want the path to move when you move the link, then you can use a relative path. Just bear in mind that it stores the relative path and only resolves it from the link's current location when you try to access it.
A hardlink is similar to a symlink, in that it still points to a file, but it is limited to the current file system, but also it is faster. A hardlink points to a specific inode on the disk, instead of another location in the filesystem. You cannot have relative hardlinks.
You can consider a basic filesystem as a collection of hardlinks to locations on disk, one per file. Creating additional hardlinks just creates additional pointers to the same file. They are considerably faster because the system knows exactly where on disk the file it needs is a symlink has to be resolved, and then that new file has to be looked up and resolved , but because of this it's limited only to inodes on the current filesystem.
The filesystem automatically tracks the number of hardlinks pointing to a particular inode, and simply deletes the inode when that count reaches 0. The -n and -f options unlink and remove the original 'Current' and allow creation of the new one -s for soft link.
