I promiss I'll check that just as soon as I have access to such a machine :-) in the meantime, I asked the list because I don't... > >is there an official procedure for this or should one > >"improvise"? > > > What raid level do you want to add? RAID1. there are two standalone disks in there, they want to add another to mirror one of the existing ones. > > In theory, SecurePlatform is no different than any other Linux.

One more thing - recompiling the (non-existant) kernel source may also violate the warrenty, so that's why I was wondering if the official supported kernel supported MD, or the older method of /etc/raidtab (whatever it was called) or none at all. > The general procedure for setting up md on the fly is to set up the raid > with one failed disk (being the disk that currently holds the data), > copy the data to the raid, and then attaching the last disk to the raid. > I've only tried it on raid-1 before, but there is no reason for it not > to work on any other raid level. no, except the client wants to do it on the fly with a living system, at minimum downtime. sounds a bit of a problem to me. the howtos indeed tell you to set up MD in failed mode, move over the stuff to it, reboot the system from the new MD, format the old disk (or if you are sane, get a virgin disk) and "re"attach the "failed" pats of the raid. they don't discuss doing it in-place by just adding a disk and synching to it. > Depends on whether the SecurePlatform installation allows raid > installation. well, that's something I'd love to know. -- The Energizer bunny Ira Abramov http://ira.abramov.org/email/ ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
