Thank you!

I created SSH keys within UNRAID and when I SSH into a remote host I get the following messages. The SSH connection is successful but I'm just wondering if I need to do anything with these messages?

I got a UPS Power Failure alert but I did not get a Power Restore alert. Is this because this power outage was too short. ie 9 seconds? Thanks.

I havent had a chance to boot into safe mode. Will give that a go and report back. It still happens usually when a disk spins up or if I browse a large file directory.

By looking at the UNRAID UPS Panel - UPS Load parameter. I've added the switch, my servers idle at 27W each and when the 4 disks are running go up to about 60W. Thanks. I will give the power outage simulation a shot this weekend.

@JonathanM OK. I think I got it now. Mains Power --> Surge Protector 1 --> UNRAID 1 and UNRAID 2 Mains Power --> UPS Power --> Surge Protector 2 --> Dummy load. ie. like light bulbs that draw equivalent Wattage For the 'test', cut the power on Surge Protector 2 with the simulated 'load'. UNRAID 1 and UNRAID 2 does not loose power during the test (Surge Protector 1 does not get switched off). My two UNRAID boxes draw about ~120W (with disks spinning) and the UPS is rated at 650VA/390W. Thanks.

@JonathanM If there was a power switch at the wall socket, could I just switch that off to simulate a power outage? Thank you for the suggestion. Going by that, I would do something like this: UNRAID 1 --- PSU ---> Surge Protector 1 UNRAID 1 --- USB ---> UPS UNRAID 2 --- PSU ---> Surge Protector 1 Network Switch --- Power ---> Surge Protector 1 UPS ---> Surge Protector 2 --> Mains Power (wall socket) Therefore: Mains Power --> Surge Protector 2 --> Surge Protector 1 1) All devices OFF 2) Power on Surge Protector 2 3) Power on Surge Protector 1 4) Power on UNRAID 1, UNRAID 2, (Network Switch already ON) Start Test 1) Power off Surge Protector 2 Watch for: 2) UNRAID 2 shutdown 3) UNRAID 1 shutdown Adjust power outage trigger time to 1 or 2 mins (depending on UPS capacity) to reduce UPS battery drain. Thanks.

Do these UPS Settings look alright for two UNRAID boxes connected to one UPS. Basically, I would like UNRAID 2 to shutdown after 5 min power outage, then UNRAID 1 to shutdown after 10 min power outage. How about the Battery level and Runtime settings? Do they look alright. Just would like another pair of eyes to take a look... basically I'd like UNRAID 2 to shutdown before UNRAID 1 no matter the circumstances, ie. power outage, battery levels, runtime and time on battery UNRAID 1 UPS cable: USB UPS type: USB Device: Battery level to initiate shutdown (%): 30 Runtime left to initiate shutdown (minutes): 10 Time on battery before shutdown (seconds): 600 / 10 mins Turn off UPS after shutdown: No UNRAID 2 UPS cable: Ether UPS type: Net Device: 192.168.1.2:3551 Battery level to initiate shutdown (%): 40 Runtime left to initiate shutdown (minutes): 20 Time on battery before shutdown (seconds): 300 / 5 mins Turn off UPS after shutdown: No Also what approach to run a safe power outage test. I would like to avoid a parity check (if possible) on the arrays if the UPS failed to switch to battery power or initiate shutdown properly? Thanks.

I initially thought this might have been a simple question. Diagnostics attached. Thanks. tower-diagnostics-20240318-1712.zip

It really depends which disk. Take a look here: https://docs.unraid.net/unraid-os/manual/storage-management/#replacing-faileddisabled-disks

Thank you!

I have recently installed a larger disk in the array and copied a bunch of files to it. I noticed now, when for example I view the contents of the share using the Shares tab and the File Manager, a job is kicked off and on the bottom status bar showing in red: The CPU utilisation spikes and I need to wait for a while before this job to end... What is this job and is their anyway to avoid or reduce the effect on the CPU? Has it got something to do with the Dynamix File Manager which I also have installed? Thanks.

I have been using the Preclear Tool on a couple of disks now which some success. It's nice tool to determine which disk may be EOL. I usually print out a copy of the preclear preview log upon completion and include with the disk. I'm just wondering if the preclear logs are available on the system *after* the disk has been unmounted?

Thank you. I will give the disk a second chance and will keep an eye on it.

The disk passed the SMART extended self-test. Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed without error 00% 8901 - # 2 Extended offline Completed without error 00% 40383 -
