Nothing to do with SCSI, but I just did the fdisk/growfs thing a short while ago. I copied (dd) everything off a failing drive to a new one with different capacity and then fixed up the partitions/slices. I was nervous but it went fine. It's certainly a case for "measure twice, cut once." I'm still just testing here. In practice I may just add another array / logical volume. Much less tricky. Also, the array reconstruction took a looong time. While I was running while it was happening, I still had to wait for the reconstruction to finish before doing anything with the space. Adding a new array would be much quicker, if you're in a hurry to use the new capacity. For the archives: while array reconstruction was in progress bioctl showed the new disk as "Unused" and separate, though it was part of the array. After reconstruction finished bioctl showed everything just fine. Since I'm playing with -release just now it may show differently in snapshots. -- Darrin Chandler | Phoenix BSD Users Group [EMAIL PROTECTED] | http://bsd.phoenix.az.us/ http://www.stilyagin.com/ |
