If the swap drive fails, your system dies horribly possible in ways that could mess up the filesystem. Why make a system with redundancy suddenly have none? Better to buy a pair of those drives and run swap on another raid1. -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

Following the suggestion by Len, is that possible to install another raid1 (just for additional disk space, say swap) while preserving the current Debian amd64 etch on present raid1 (Linux driven)? This machine is ssh with Debian i386 as graphical interface on another machine so that reinstalling everything on new HDs would not be attractive. Also, I am pressed to fish some computations. It is possible, swap is dynamic under linux. swapon/swapoff are the tools you are looking for. man swapon Patrick. -- -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

On the other hand you (mostly) don't have redundant RAM modules in your system and if one fail it is the same effect. Bye -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

This machine is ssh with Debian i386 as graphical interface on another machine so that reinstalling everything on new HDs would not be attractive. Also, I am pressed to fish some computations. Sure. Just add the two new drives, and use mdadm to create another raid1 on the new drives. Should be very simple and should have no effect on your current raid at all. -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?
