Q: What causes "Ignore ownership on this volume" to reset?

Asking again because I am really interested in this.

 

"Ignore ownership on this volume" periodically gets unchecked somehow on my internal storage drives, all three of them at the same time, and I want to know what can be possible causes. Nothing unique or any actions on my part come to mind, I only notice because Finder is set to Show All Files so hidden system folders icons will have the red bit on them.

 

Here's the bit that's changing on it's own or by me inadvertently.

    Did you try booting into Recovery (command R) and run the DiskUtility>First Aid on your Macintosh HD(s) ?

     

    You can do more research, but this link Re: Ignore Ownership on this Volume - Won't Stick proposes a terminal command to remove the /var/db/volinfo.database  —I have not tested this.

    Dragging a copy of the file to the desktop by holding the option key may be a good idea

    Hey, cool. I may try that if and when it happens again.

     

    I sort of hate messing with files in the account hidden folders. It creates .ds_store files and they sometimes seem to cause Spotlight to do a never-ending indexing of that folder i.e. /var, /usr, or whatever.

     

    Thanks for the link, something to go on.

    I discovered that after running the Internet Apple Hardware Test (Option-D) with extended option checked, my boot drive had the Ignore Ownership option checked. This is not supposed to be possible on a boot drive, and thereafter the Macbook Pro (Yosemite) would not boot. It would not boot from anything - Hard Drive, Recovery Drive, Internet Recovery, or Install DVD.

    The only way I found to recover it was to remove the Hard Drive, Load it into a USB harness, and switch off the Ignore Ownership option using another Mac. Then after putting the Hard Drive back int the MBP it booted again.
