As like many time before, as soon as Isent the e-mail with a question, a lightbulb went off in my mind. 1. Unmount filesystem (I only have one in the group) on Logical Volume. 2. Resize Logical Volume since I stretched it before (did not know how all that goes). I resized it to well over the size of sdd7. I used LVM GUI for filesystem+LV resize in one go. Now: 3. pvmove to move away all allocated extents 4. vgreduce I hope those last too go without a problem. Will report back. -- Ljubomir Ljubojevic (Love is in the Air) PL Computers Serbia, Europe StarOS, Mikrotik and CentOS/RHEL/Linux consultant _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
