Issue Details

I recently migrated NI Phar Lap ETS to NI Linux Real-Time operating system (RTOS) of the PXI(e) controller. I had Reliance file system option in NI Phar Lap PXI(e) controller which preserve data in the event of a power loss. Are there any similar file system in NI Linux RTOS PXI(e)  that ensures reliability?

Solution

The default File System of NI Linux RTOS on x86-based controllers (PXI(e) with LinuxRT, cRIO-903x, 904x and 905x series, sbRIO-96x8 and sbRIO-96x9) is ext4. 
The ext4 use journaling filesystem which ensures reliablity.
