ReadyNAS Pro Business - Freeze
Hi,
My ReadyNAS Pro business running OS6.9.3 froze last night for the very first time - totally inaccessible, unable to 'ping'. When I checked my cabinet, the NAS was still running - fans spinning ...
Certainly there is evidence here of file system corruption, even though the disks are healthy.
It'd be good to make a full backup of your data. Then after that, perhaps try running a scrub using the volume settings wheel (on the volume page). A more conservative approach would be to do a factory reset, set the NAS up again, and restore the data from the backup.
Understood.
Actually I did a factory default 2 weeks ago when I upgraded my CPU to an E7600 to help with Plex transcoding. A few days after that, I then upgraded to 4GB of Crucial PC2-6400 DDR2-800 memory - I'd been running OS6 on the 1GB factory default which came with the ReadyNAS when it was running OS4.
Could the root cause of this problem be related? If so, is it more likely to be one of the memory modules than the CPU?

My guess is that the memory is more likely to be a problem than the CPU. Perhaps run the boot menu memory test for a while - if only to rule it out.
Took some time to do the memory test - turns out my upgraded ReadyNAS Pro Business running 6.9.3 didn't have the necessary memory test files in the flash boot memory, but fortunately MDGM fixed this for me...
So, after removing both modules and cleaning the memory slots and modules with contact cleaner and then reseating them, the memory test past - successfully completed 40+ cycles over a 50+ hours.
Hopefully that will be the end of my problems.
Appreciate your help!
Thanks Stephen - I'd forgotten about that boot menu test :-). The memory was my first suspicion too. Gut feel says I should have 'blown out' the previously unused memory slot before inserting the module - there'll have been a few years of dust in there.
Will have to try it next week though due to lack of opportunity. In the mean time I'll run the disk scrub. Then, before starting the mem test I'll remove the modules clean contacts and reseat them, test and report back.
Trouble with intermittent problems is it takes time to narrow things down, and at the end of the day you're never quite sure. Sound like if the test passes, I should factory default and start again to be sure?
Fortunately this is my backup NAS so nothing is being affected outright right now - not great though!
Really appreciate your help! If anything else comes to mind in the meantime I'd love to hear. Kind regards...
