Hi Mathias, PLEASE don't always quote everything you've just written a few minutes ago when replying to yourself. This makes these responses really, really inconvenient to read. Concerning your problem at hand: Don't panic, everything should be fine. Your RAID did what it is supposed to do: protect your from a single drive failure without inducing downtime. A disk has failed, and now it's time to replace it, that's nothing out of the ordinary. You don't need to shut down your system - RAID systems have "no service interruption in case of an accident" as a design goal, and md is rather good at meeting just that. If your SATA controller supports hotplug (and if it's SATA-300, that much is for certain), just unplug the old drive, replace it with a new one, clone your partition table setup (if any) from an old driver to the new one, have md pick up the disk and integrate it into your array, and see how everything'll be taken care of automatically. md will resync the array once the new disk is part of the array, and it will be smooth sailing again afterwards. Just make sure you don't pull out the wrong drive, but correctly identify the broken one. ;) While the array's being worked on, you can do whatever you intended to do with your seemingly healthy array from of a few hours ago - the only difference it that (some) things will go slower, but that's about it. The only serious problem you could run into is a second and third harddrive failing while your array isn't 100% OK again yet - but even in that case, you'd have a backup ready, now wouldn't you? :) -- with best regards: - Johannes Truschnigg ( johannes@xxxxxxxxxxxxxxx ) www: http://johannes.truschnigg.info/ phone: +43 650 2 133337 xmpp: johannes@xxxxxxxxxxxxxxx Please do not bother me with HTML-eMail or attachments.
