1st off, i know enuff to be dangerous, but that's about it. I had a friend that has moved far away that set all this up for me, and i'm stumped. 

 

i've used the https://docs.unraid.net/legacy/FAQ/parity-swap-procedure/   switching out a 4tb with a 12tb new drive

1st time it went to 27% and just sat there for 3 days 

i kept the old drive i was replacing intact, so i had to hard boot (using the web gui - it wouldn't let me stop the array or do anything) and replaced back with the original 4tb drive 

rebuilt parity back to original status, this went fine 

 

tried again - same steps -- it got to 3 % and sat for 4 days -- had to do a hard reset - put the old 4tb back in and redid parity -- this worked fine 

 

tried a different 10tb drive -- it got to 1% and sat for 2 days -- so im currently doing it all back over again with the 4tb drive to get me back to where i was 3 weeks ago

 

BTW -  i tried to download diagnostics while it was trying to copy to the new parity drive but it would not create a ZIP FILE  - but i have attached the diagnostics from today when i started the parity rebuild with the old 4tb drive -- i've attached this file 

 

thx in advance for your help, as i'm stumped and not that swift with all this

Rebuild is still going on in the posted diags, post new ones if it stalls.

ok, so i put everything back the way it was and parity rebuild went fine (on arc2) -- attached diagnostics 

 

i used the SAME 10tb drive that just "ground out"  for 3 days on arc2 and tried to put it into a different unraid server (unraid1) thhis went fine - without issues -- so i'm thinjking it isn't issues with the 10tb drive - ive attached daigs for this server as well (unraid1) 

 

when arc2 was just grinding for a couple days, i tried to create diagnostics but it wouldnt create it, it tried  --  but overall just sat there -- i took a screen grab of this - perhaps it will help...

 

hope some of this helps - not sure of my next steps 

 

thx

You can try and get new diags if it stalls again, or at least get the syslog.

thx for the advice as always !  

i was wondering if perhaps its my sata controller(s) -- over time it seems like im getting alot of the UDMC errors (?)

 

just like this last time a drive "said" it was bad, but when i removed it and put it in a different unraid server, it performed without an issue -- this happened with that 10Tb drive just now -- wouldn't work in one server, worked fine in a different server.... i dont mind spending a few bucks and replacing the sata controller, if you think that would help, but i'm really nervous about doing it tech wise (im an idiot on this stuff) and not even sure what would be best to replace it with..... thoughts? 

 

thx in advance

That's usually a SATA cables problem, with some LSI HBAs it can be a firmware issue.
