What is Scrutiny? An application that monitors SMART statistics on HDDs and SSDs. This is useful to monitor the health of an array of disks like what unraid handles. As someone who’s had disks silently start failing and loosing data without notice (like unraid dropping the disk out of the pool), an application like this will be extremely useful.Continue reading “Installing Scrutiny on Unraid”
Like many, I had issues with sqlite database corruption on Unraid. I found while researching it that it had to do with file locks in the fuse file system unraid uses to merge disks. I found the best way to circumvent this is to use the cache disk for those databases and map them directly. My docker mappings now point to /mnt/cache/share instead of going /mnt/user/share. This solved the issue better than the 6.8.0rc5 fixes. This avoids the system in question completely and solved the stability issues for me.
I started my original NAS build with inexpensive quality consumer components, but by now its become a strange chimera of enterprise and consumer gear. The main goals: low power, quiet, high storage density
With the focus, the main decision was on a case, 8 hdd’s were the minimum number of bays, and having a few 5.25″ bays allowed me to use a 5×3 cage to add more hdd bays. From some research, it can also be found that another stack of hdd cages can be added to the case with relative ease, bringing the total number of disks held to ~21.
