Hello everyone,
Some months ago I set up a Intel NUC 13 (i5 13th gen, 64 GB) as homelab to run 9 little VMs.
The SSD i mounted is a 2TB Samsung 990 PRO.
Space used on the SSD is 107 GB out of 1.84TB and the vms are 8 Debian and 1 Ubuntu doing really little things (web servers which are used only by me, Asterisk PBX, DNS Server, Reverse Proxy).
CPU usage is always 1 - 1.5 % and memory lower than 16 GB. Also HD usage and I/O are really low.
SSD is a single LVM volume and I have 2 backup tasks running every night.
In something about 5 months the SSD wearout treshold is showing 18% with only 2.5 TB written
I've read of usage problems in ZFS configuration and I can understand them, but I wasn't expecting this on a single disk.
I'd be glad if someone can tell me where I'm wrong, or better if that wearout % is not actually the real one as I'm thinking when reading SMART values.
Thank you
SOLUTION: It seem to be an SSD problem: searching for the specific SSD model: The 990 Pro, I found lots of people with same readings even on Windows.
Hope this will be helpful to someone
