XigmaNAS

I added an additional SATA disk in my server for backups, added the disk normally in the manager, formatted it to UFS, and when I tried to mount it it showed "Operation not Permitted" error in the logs.

After searching for the error I found a post suggesting to do "sysctl kern.geom.debugflags=0x10". After doing that I was able to mount the disk manually, but if I reboot the server the mount will fail again.

Is there any way of fixing this error without messing with kernel variables / sysctl?

there are a sysctl.conf tab in webGUI since 9.1.0.1.847 and newer version to add sysctl kern.geom.debugflags=0x10 from webGUI and makes changes permanent in enbeded install ( and in full install too)

Thanks Raúl for your answer,

I understand I can modify the sysctl so the system will let me mount the disk in the future, but I was wondering if there was anything I can do to fix the underlying problem (possible geometry error).

First, because I will prefer not to modify that variable (it is there to protect from something) and also because I dont want to have problems mounting that disk in another machine (i.e. a Linux box with UFS support) in case I need to recover data.

I want to use the sysctl modification only as last resort.

Same thing happened to me, somehow the boot sector of my 16Gb. Apacer SSD got corrupted, even a second one I keep for backup sake crashed.
After expirencing the same error as eiger3970 I tried to format them both as FAT32, hoping they would be fit again to be able to install N4F again.
With the help of "Universal USB Installer" utility:

I could download the mintlinux ISO and install it on an USB drive to install N4F again to one of the Apacers.

After the initial setup I restored my backup of the config, and started restoring OBI.
With help of the "tools" -> "command" option, find below.

Install OBI:
fetch https://raw.github.com/crestAT/nas4free ... er/OBI.php && mkdir -p ext/OBI && echo '<a href="OBI.php">OneButtonInstaller</a>' > ext/OBI/menu.inc && echo -e "\nDONE"


Manual installation of Plex when OBI fails:
fetch https://raw.githubusercontent.com/JRGTH ... nstall.php && mkdir -p ext/plex-install && echo '<a href="plex-install.php">Plex Extension Installer</a>' > ext/plex-install/menu.inc && echo -e "\n=> Done!"
