Hello, I'm using a software raid with mdadm (mirror). A few days ago the mdadm removes during the boot process one disk and sets the raid inactive. The disk contains no errors (smartctl) and nothing is reported in the logs. I reassemble the disk and activate the raid again. Reboot the system and my disk are in sync and everything works fine.
I'm a little bit confused about it. Does anybody has got an idea, why the array lost a disk? Thanks
