Hello, I have three MDs on two HDDs in RAID 1. In last days, thanks to my monitoring (which is installed longer time), I have recognized, that one of these MDs is automatically started resync. First was at 25th October and second resync of the same MD was today. It started in same daytime (about 4:00 AM). Now is MD resynced and working well. Can someone tell me what means this automatic resync? Is it standard? Is it means some possible problems with one HDD (but other two MDs are working without resync)? Thank you Martin Šťastný
