Sorry, I don't think I made myself clear. If the old disk was swapped out and copied, then the old disk is "clean". If this disk gets back into the same machine as the raid array, and the machine is rebooted, mdadm IS GOING TO GET CONFUSED. Yes, but Andrei is using an HP Smart Array Controller, not software raid.
I've also been bitten by hidden RAID metadata on individual disks.
oh, me too. BTDT. I don't know how a hardware controller usually deals with it - if a disk isn't actually dead, but maybe kicked out due to timeouts or smart warnings, removing all trace of its RAID "membership" sounds like a sound thing to do when it is failed.
BTW, I've also seen software raid (mdadm) get confused by disks out of a hardware raid controller.
Now that's an interesting one. -- Per Jessen, Zürich (7.1°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
