I effectively have 1 drive /dev/sda (it's actually a hardware raid 10 array) I have lots of free sapce. I want to resize my partitions (boot, home, /) bigger. Going to use Clonezilla to make an image of each partition and save it on another box. Then re-partition and format new bigger partitions. Then restore images with Clonezilla. But I know UUID's will be wrong and I don't feel like creating new ones. I just want to use /dev/sdx Am I correct in assuming I only need to edit /etc/fstab and /etc/grub.conf or is there anything else I need to edit? Thanks -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada

I think you may make a mess out of what you have. You need to know if your Hardware Raid Controller Supports Online Resizing. If so you may be able to grow that then if you have used lvm you should be able to just resize the volumes. Some controllers do not support this method. This way no fstab editing is required. What you need to know is: The size of the configured raid controller volume. If it's already bigger than your Linux LVM then you can resize (grow) you Linux LVM. All with haveing to worry about file permissions. John

Dump will preserve the information you need and then restore will allow it to use the new larget partition cleanly. Some of your other cloning software (I don't know about Clonezilla) including dd(1) will try to duplicate the space as it was on the old partitions and not use the new space. So dump the partitions redo the partitions restore in to the new partitions If you are changing root (/) and/or /boot you have to build a minimal bootable system on it/them. But, really root and /boot do not need to be very large if you put growing stuff in its own partitions such as /home, /usr, /var. ////jerry> > Thanks > > -- > Robert Arkiletian > Eric Hamber Secondary, Vancouver, Canada > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos
