By the way, something else important :-)
Somebody had a glitch on their array because they swapped a disk out, then tried to add it back as a spare except mdadm got confused.
Make sure you use a *different* machine (or hotplug this drive *after* your array is up and running), and do a "mdadm --wipe-superblock" on the drive.
Otherwise, if this disk gets back into the machine, you could find yourself with a recovery scenario on your hands :-(

Hi, Wol,
Thanks. RAID5 will be used on the same machine it is installed right now. BTW, mdadm is related to osftware RAID, in this particular case I have hardrware RAID. I stopped using software RAIDs long time ago.
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. -- Per Jessen, Zürich (8.6°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
