so all my unraid servers are running 6.12.13

each night my main server wakes up the mulitple unraid backup servers and then rsyncs over

but ive noticed a few times...  rsync error.. and when i manually do it.. the port 22  basiclly turned off

so on the one back up server what i do is under mangement networks  i disable ssh   save.. it logs me out to the login in screen

then i re log in  and i re goto management networks and re enable ssh.. and then im able to rsync again...  this lasts so many days   and then ssh is disabled again  i gotta do the repeat above disable   re login in the gui  re enable.. and then rsync works again 

 

is there a reason  why ssh  is breaking down  is there a way to force it to stay working fine or something?  is this a known problem or something?

You should post your system's diagnostics taken when you notice this happening.

 

The only thing that occurs to me is the flash drive dropping offline so that the setting reverts to default value.  The diagnostics might show if this is what is happening, or suggest something else going on.

it may not give logs  as when it works..  after the rsync is done..  it shuts down the remote computer..  here is the logs i noticed the first error i havent seen before this one keeps popping up... i can get you diagnostic logs  but it didnt see issue but here is what the warnings show

Oct 21 06:07:11 Rambo kernel: x86/split lock detection: #AC: crashing the kernel on kernel split_locks and warning on user-space split_locks
Oct 21 06:07:11 Rambo kernel: ACPI: Early table checksum verification disabled

Oct 21 06:07:56 Rambo kernel: BTRFS info (device loop3): using crc32c (crc32c-intel) checksum algorithm

 

ill keep an eye and try to see if i can do multiple wake ups shut downs to recreate the error    the reason i notice the problem  is when the remote computer is still on during the day when it should be off then i know the rsync didnt work  and the ssh to shut down the pc  didnt work either

 

here is the current diagnostic  ill post the diganostic when it fails again

 

now i told it to reboot.. but i not sure if it rebooted or not as it says its been up for 5 hours   so maybe the glitch still in there in the diagnostic 

 

and it looks like my other 2 unraid back up servers are sshing fine as there user scripts logs shows it wakes up  rsyncs and then shuts the unraid servers down... its just this current one that having the issue

@itimpi

ok its back..  i noticed  my server was still on..  and i cant ssh in..   here is diagnostic  i see its having some ata issue

 

but hard drives are online  and  ssh should be working  but maybe the ata disables the SSH?

 

rambo-diagnostics-20241114-0904.zip

does it show  that if a drive has ata issues  that it corrupts the SSH  ive shut down the server since thursday

i guess the drive has a loose hot swap as no issues with the actual hd..
