May 9May 9 I've been getting everything set up, haven't started an array yet. I noticed that my backplane LEDs blink off in a 1 second interval, constantly. This does not happen in BIOS -- the LEDs stay continuously on for each drive that's connected. Checked the htop I/O tab to find this entry at the top: PID USER IO DISK R/W DISK READ▽ DISK WRITE SWPD% IOD% Command 4359 root B4 31.75 K/s 31.75 K/s 0.00 B/s 0.0 0.0 /usr/libexec/unraid/emhttpdEvery other process has 0.00 for DISK R/W, Read, and Write. Setting the htop delay to less than one second (ie htop -d 1) shows the emhttpd entry in the list "pulsing" into existence and quickly disappearing at the same moment that the backplane LEDs pulse off.What are these reads for?Other notes: First time using Unraid, haven't been able to find an answer to this yet. I've tried changing the Tunable (poll_attributes). My drives are second-hand SAS drives, and this seems to happen regardless of which ones are plugged in, or how many of them are plugged in. The pulse also seems to correlate with sounds coming from the drives. I've performed a long smartctl test on them overnight and most of them came back as completely healthy. I'm using an LSI HBA card with a Jonsbo N2 case.
