[opensuse] Mount /opt on separate RAID
I have a SLES10 SP1 install in a hardware RAID 5 config. I am looking at adding another Array to the server and what i want to do with that array is mount the entire /opt directory and all its contents onto this new array. Is it possible to do this with the current install or would this break things by mounting to the new array? I really don't want to have to reload everything on this server. Here is what i was thinking: Boot the system, with the new drives installed, with the IBM servraid disc. Configure the new array, prolly RAID 0. Here is where i need some help. Can i then boot the system with SLES10 install disc and mount the existing /opt directory and all its contents on the new array?

Create the new partion on the new RAID array. Copy over all the existing /opt, edit /etc/fstab and then remount /opt. If your previous /opt was a directory under /, you'll probably want to delete all the files in it, after you've verified the new /opt works. -- Use OpenOffice.org <http://www.openoffice.org> -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

OK, i have partitioned the array and have formatted the physical drive. I used these commands: fdsik /dev/sdb -n -p -w Then to formatt i used: mkfs.reiserfs -f /dev/sdb Now to copy over the existing /opt folders and files, i am trying to use: cp /opt/* /dev/sdb/opt and get "not a directory". What is the correct way to copy over the existing /opt folder and files as to not break anything? Symbolic links and what not, i do not want to break anything. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It doesn't work that way, you must mount the filesystem. Try this procedure: - mount /dev/sdb1 /mnt - tar cf - /opt | tar xvf - -C /mnt Once you check everything was copied as it should (you better do a backup also): - umount /mnt - rm -rf /opt/* - add "/dev/sdb1 /opt reiserfs acl,user_xattr 1 2" to /etc/fstab - mount -a PS: Did the mkfs.reiserfs command succeed?, i think you should have given /dev/sdb1 as the parameter (not just sdb) Ciro -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

You have to mount it first. For example, you could create a mount point /tmp and mount it there. Also, I thought you wanted another RAID arrary. The easiest way to do all this is in YAST partitioner. You can use it to create the partition or RAID array and specify where to mount it. -- Use OpenOffice.org <http://www.openoffice.org> -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Not awake yet. Don't use /tmp. Create something like /temp or /optx etc., that's not already in use. -- Use OpenOffice.org <http://www.openoffice.org> -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
