OK - last Sunday for the third Sunday in a row in August : my TrueNAS server was offline / powered off / shutdown…
It’s a HP N40L - 16 GB ECC RAM and 4 x 4 TB HDD zpool in RAIDZ+1 (i.e. like RAID 5) which gives me about 11 TB of capacity… The system comes with Dual Core AMD Turion CPU - it boots off a single SATA SSD (256 GB)…
No SMART issues or alerts… I’ve no idea what’s causing it… There was a scheduled job to “scrub” the zpool weekly - but didn’t co-incide with each outage… Nothing in any logs to indicate why… I can’t even diagnose the exact time it went offline / powered down…
So - I’ve disabled the scrub task - and - I now have a scheduled task (it uses cron - but you can’t see the crontab in the FreeBSD shell) on Thursday morning at 2:00 am to reboot… Then I also have cronjobs on my Pi4 system that uses the TrueNAS storage to restart the daemon that uses the storage, and same thing with JellyFin - about 3 am…
That worked fine overnight last night (this morning).
So - I’ll have to check if it’s still up (TrueNAS) on Sunday morning… Fingers crossed…
I might then change the scheduled scrub task to enabled but run on maybe Friday morning before sparrowfart (Aussie-ism for “dawn”)… See how I go…
Damn - I really should invest in a spare power supply for this box… That’s the mostly like thing to fail next - touch wood : those 4 x 4 TB (WD Green - i.e. 5400 RPM) have been going since late 2019 with no issues (previously had 2 x Seagate 3TB drives fail in it within two years). I can lose one HDD and retain functionality… Annoyingly - that AI bubble also seems to have affected spinning platter HDD prices too! It shouldn’t have… I reckon it’s price gouging, raising prices across the board…
