Server unreachable when starting Parity Check/Rebuild

[rushone2010]

Hi Guys,

 

I've recently been replacing drives on my Unraid NAS to larger ones as per documentation.

I've successfully replaced multiple drives with no issues up until now, including the Party drive.

 

When a Party check starts, the server becomes unreachable and all docker containers appear to be down as well.

I have also now tried to replace the Parity drive and attempt a rebuild, however same issue occurs.

This happens within the first few minutes of starting the check/rebuild.

I've attached the diagnostics/syslog files. I've taken a look at them myself but not certain what I should look for. Please let me know if theres anything else I can provide.

 

Any ideas? Thank you!

This sounds rather like it could be a power issue as the processes are ones where the power draw will be maximum as all drives are in simultaneous use.  What PSU model do you have?  Are you using splitters on any of the power lines?

I'm using a repurposed flex-atx PSU I bought a while back for a different low profile build: https://www.amazon.com/gp/product/B07QGMX5DW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

This is my current build: https://pcpartpicker.com/user/rushone2010/saved/#view=BcPh7P

 

This has served me well and has had no issues in the past. It ran with the older drives just fine for months. I think I may have somehow damaged the data/config of unraid swapping every drive out with new ones. I've now done a parity rebuild and 3 data rebuilds and started to have this issue a little while back.

 

I've had to do multiple hard shut downs now which is definitly not good, but the only way to "bring back" the server.

 

I run a lot of docker containers that have continued to run during the rebuilds.

 

Honestly I just want to avoid completly rebuilding this unraid server as it will take ages with 2 TB of data and all the docker instances I have configured.

I'm not really using a splitter, buit I do have this running on a UPS: https://www.apc.com/us/en/product/BE850G2/apc-backups-850va-120v-2-usb-charging-ports-9-nema-outlets-3-surge/

That power supply looks to me like it may be underpowered to handle the peak power draw from your setup.   Do you have another one you could use to test this out?

[rushone2010]

Currently I do not. If I am to replace it, what watt's should I target with what I got?

 

Also attached syslog/diagnostics during the crash.

500W + (all Video Card requirements) + (5W * HD) = Your Power Supply Requirement. It's better to have more power than less because the PSU will never provide more than needed.

500W for a i5 with no GC? Did you look at the part's list at all? PC Part Picker Estimated Wattage is 237W. This is a 9 month old PSU from SilverStone, which for 9 months handled the same amount of HDD's of smaller size with no issue.
