kamhighway Posted April 23, 2015 Share Posted April 23, 2015 Are there any conditions under which UR would spontaneously start a parity check on its own? Yesterday, a server that had been running URv6b14b spontaneously started a parity check 2 times. The first time, I thought I must have kicked it off by mistake. But about 30 minutes after the parity check finished, the server kicked off another parity check. I'm sure I didn't start the second one. This morning I upgraded to URv6b15 to see if that would fix the problem. It did not. Here is the tail of my syslog after the update to v6b15: Apr 22 17:44:23 Media kernel: device vethab52d97 entered promiscuous mode Apr 22 17:44:23 Media kernel: docker0: port 5(vethab52d97) entered forwarding state Apr 22 17:44:23 Media kernel: docker0: port 5(vethab52d97) entered forwarding state Apr 22 17:44:23 Media avahi-daemon[6999]: Withdrawing workstation service for vetheeff233.

Is that an unclean shutdown? Link to comment
trurl Posted April 23, 2015 Share Posted April 23, 2015 Put your flash in your PC and let it checkdisk. A corrupt flash can prevent unRAID from recording the run status and it will not know you did a clean shutdown. Link to comment
kamhighway Posted April 25, 2015 Author Share Posted April 25, 2015 @trurl thanks for your help. That seems to have done the trick. Link to comment
