ReadyNAS Pro 6 has become unstable and regularly hangs
My ReadyNAS Pro has started hanging after running fine for many years.
Currently running firmware 6.9.2 but have had the same problem with the last few versions released.
I've tried disabling the four apps I have running, as well as turning off features such as the scheduled snapshotting.
But still, since around November 2017, I've found my ReadyNAS will just freeze and needs the power button holding down to shut it off and then press again to start it up.
What sort of things can cause this hanging in the ReadyNAS Pro and what logs can I check to look for any clues?

Start by downloading the log zip file, and look in volume.log.
Look at the SMART stats for the disks and make sure those look healthy.
Then scroll down and look at the space usage in /dev/md0. That is normally around 20%. Let us know what you are seeing there.
Thanks for the pointers Stephen.
volume.log shows all disk SMART info as passed/healthy, and no errors or retry counts for any of the disks. I don't claim to understand what most of the info in the volume.log is about.
I'm using RAID5 if that is of importance, using 4 disks.

/dev/md0 4.0G 717M 3.0G 20% /What services do you have enabled?
As I have the exact same issue since some months, but my /dev/md0 shows more than 20% I wonder if that is giving a hint and possible action to try?
