Back from vacations! So, to answer Darren:
Dangerous because I destroyed one file system because of this :)! Well, with the help of Veritas support in Germany we were able to restore the other part of the concat and thus restore the file system intact. Perhaps mixing the id's is a feature that occurs with EVA. When I move a disk between servers the id doesn't necessarily stay the same. Moreover if I present a new disk to the server it might go over the id of the "move disk". Sometimes this causes VVM to recognize the disk as "already initialized" and at times it's even unable to put the disk to a new disk group; it can only be used as a backup disk for some other disk. This requires quite a lot of fiddling (offline, rm, online, scandisks and whatnot) to get everything right. If I go on with the temp disk plan when resizing disks, any idea how big the temp disk must be? At least privlen? -j- -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Darren Dunham Sent: jueves, 29 de marzo de 2007 19:03 To: Veritas-vx@mailman.eng.auburn.edu Subject: Re: [Veritas-vx] resizing a device > Actually my first live-and-learn experience with VVM was due to moving a > disk back and forth between servers (fast, easy and dangerous way to > move 4T of data); Why dangerous?

"the id's got mixed" just shouldn't happen. I realize it's not part of your current issue, but I would be interested to understand more about what happened in this case. > Thus, I'm looking for a way to resize a file system without too much > hassle with temporary disks. You have chosen to set up your system in a way that few others appear to use: a diskgroup on a single LUN that you plan to resize. The FS and volume resize are trivial. Your issue is that dynamic lun resize appears to require multiple disks within the diskgroup to work. The only ways I know of around that issue are even more fiddly than using a temporary disk. (If you scripted it, the temp disk thing shouldn't be much of a hassle, but you would have to maintain it). -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
