Note: plexes must be on slices, not on raw partitions!

To set up a new vinum volume

• Make partitions for big volume using fdisk interface within the /stand/sysinstall utility.
• Label space in partitions with no mount point using the label editor within the /stand/sysinstall utility.
• Format each label with: newfs /dev/ad5s1e (use your partition of course)
• Re-Label each label using disklabel -e, changing fstype to 'vinum'
• create the vinum config file (this is for my 3 drive stripe): /usr/local/etc/vinum.conf

drive prima device /dev/ad4s1e
drive prisl device /dev/ad5s1e
drive secma device /dev/ad6s1e

volume pincushon
plex org striped 64k name diskarray1
sd length 0 drive prima
sd length 0 drive prisl
sd length 0 drive secma

• Create the volume using: vinum crate -f /usr/local/etc/vinum.conf
• Initizlize the volume using: vinum init -w diskarray1
• Format the new volume: newfs -v /dev/vinum/pincushon
• Add line to /etc/rc.conf: start_vinum="YES"
• Add line to fstab

/dev/vinum/pincushon /mnt/data ufs rw 0 0

To enable a volume that has already been created

• enter vinum start on the command line

• Add line to /etc/rc.conf: start_vinum="YES"
• Add line to fstab

To add another drive to a concat plex

Note: This ONLY works on a concat plex. This will not work on the config example earlier in this file.

• Partition, Label, and format the new space
• Attatch the subdisk to the plex:

vinum create

drive secsl device /dev/ad7s1e

sd name diskarray1.s2 drive secsl len 0

^d

vinum attatch diskarray1.s2 diskarray1

vinum init -w diskarray1.s2

• Grow your data partition

dont forget to UNMOUT THE PARTITION!!!

umount /dev/vinum/pincushon

growfs /dev/vinum/pincushon

Last Resort Restore

Sometimes something may corrupt your array index. If you have not changed the layout of your array, and therefore your config file matches your array layout, this may bring back your data:

• create the exact vinum.conf file to match your drive layout
• obliterate the current drive config: vinum resetconfig
• initialize the vinum volume again and mount
