Hello,
I had my server running for a while, but it seems to me that my SSD-cache pool is eating SSDs alive. A lot of wear if I can read the SMART correctly.
I have an issue, when doing IO-intensive work, like downloading, unpacking, etc my whole server is slow as syrup. All this happens in the cache-pool, and I do wonder if this have something to do with my cache-SSDs being ready for replacement.
I'm thinking about moving a lot of my IO-work(for example all the SABNZBD-operations) to my ramdrive. I had great experience of moving all my transcoding to the ramdrive, so I will consider this with my SABNZBD-stuff also.
Some of the symptoms:
Slow response from dockers and web-ui of Unraid
Copy to and from cache-pool at very slow speeds
Low CPU-usage observed
Low RAM-usage observed
I have a INTEL Xeon E5-2630v4 2,20GHz as CPU, so the CPU should not be an bottleneck for this type of work.
Hopefully some of you can read through the logs, tbh, I don't know what to look for. The diagnostics was taken during these problems with slow server, so they hopefully could shed some light on these matters.
Thanks,
Thomas
