Unraid v6.6.5 freezing while transferring files & mover invoked

[minion1066]

Hello,

 

New to unraid (still on the trial).  Server is AMD Ryzen 5 2600, 16GB Corsair DDR4-2666, Asrock motherboard, various Seagate ironwolf hard drives (yes, parity is largest drive).

 

Seems that any time I am doing something with the array (backing up home computer to it, moving files between drives to balance shares) and the mover is invoked via scheduler, the entire server freezes with no response except a dirty shutdown.

 

I've kept an ssh tail session open but saw no errors at all.  The last entries before the freeze were:

 

Nov 27 19:12:45 unRaidServer kernel: mdcmd (363): spinup 2

Nov 27 19:12:45 unRaidServer emhttpd: req (38): cmdSpinup=disk2&startState=STARTED&csrf_token=****************

Nov 27 19:12:59 unRaidServer emhttpd: error: send_file, 139: Broken pipe (32): sendfile: /usr/local/emhttp/update.htm

Nov 27 19:13:08 unRaidServer emhttpd: req (39): cmdSpinup=disk3&startState=STARTED&csrf_token=****************

Nov 27 19:13:08 unRaidServer kernel: mdcmd (364): spinup 3

Nov 27 19:21:00 unRaidServer kernel: mdcmd (365): spindown 1

Nov 27 19:28:09 unRaidServer kernel: mdcmd (366): spindown 3

Nov 27 19:36:36 unRaidServer kernel: mdcmd (367): spindown 1

Nov 27 20:00:01 unRaidServer root: mover: started

Nov 27 20:00:01 unRaidServer root: mover: finished

 

Diagnostics attached (I hope).

Please try updating your BIOS to 4.80 and seeing if that helps: https://www.asrock.com/mb/AMD/X370 Taichi/index.asp#BIOS

Will do.  Letting parity check run through the night.

 

Everything else look ok?

 

And thank you.

I haven't check your diagnostic, as different disk spin up/down in short time. I suppose "server freezes" mainaly because this, this is compromise, suggest set longer sleep time or turn-on "reconstruct-write".

Ok, I've set the reconstruct-write on, installed the fix problems plugin, and am reading through the tips & tricks wiki.  Plan on updating bios this weekend (can't during the week, kids, don't ask  )

 

Thank you all, will let you know how things go.
