Installing ZFS on Solaris 10, x86

The web has many entries on how to install ZFS and here is the commands I have used.

The machine is a X4200 with (for now) two internal disks.

I need to use this server for Perforce (versioning control) software and need a lot more diskspace.

Create first a pool of all available diskspace. In this case the existing /export/home which was created during installation will be used as well.

bash-3.00# umount /export/home
bash-3.00# zpool create -f perforcepool c0t0d0s7
invalid vdev specification
the following errors must be manually repaired:
/dev/dsk/c0t0d0s7 is normally mounted on /export/home according to /etc/vfstab. Please remove this entry to use this device.

So remove the entry in /etc/vfstab and try again

bash-3.00# zpool create -f perforcepool c0t0d0s7


There is one extra disk, so lets add that one.

Here is the outputr from the format command.

bash-3.00# format
Searching for disks…done

0. c0t0d0
/[email protected],0/pci1022,[email protected]/pci1000,[email protected]/[email protected],0
1. c0t1d0
/[email protected],0/pci1022,[email protected]/pci1000,[email protected]/[email protected],0
Specify disk (enter its number): 0
selecting c0t0d0
[disk formatted]
Warning: Current Disk has mounted partitions.
/dev/dsk/c0t0d0s0 is currently mounted on /. Please see umount(1M).
/dev/dsk/c0t0d0s1 is currently used by swap. Please see swap(1M).
/dev/dsk/c0t0d0s3 is currently mounted on /metadb1. Please see umount(1M).
q/dev/dsk/c0t0d0s4 is currently mounted on /metadb2. Please see umount(1M).
/dev/dsk/c0t0d0s7 is part of active ZFS pool perforcepool. Please see zpool(1M).

So the second disk is c0t1d0

Can we just add the s2 (whole disk) ?

bash-3.00# zpool add perforcepool c0t1d0s2
invalid vdev specification
use ‘-f’ to override the following errors:
/dev/dsk/c0t1d0s2 overlaps with /dev/dsk/c0t1d0s7

Argh! so during installation the hardware RAID was choosen.
My bad! But it was first time I installed a X4200. Well, thats my excuse anyway.

So back to the drawing board. Maybe I have to install again, which is a pain since I can not set up a jumpstart server and have to install everything with the CD’s.


More to some in later posts.
