How do I add a second disk to my zfs root pool
- by ankimal
I am trying to add a new disk to my zfs root pool. Here is my current config:
zpool status
pool: rpool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
c0d0s0 ONLINE 0 0 0
errors: No known data errors
bash-3.00# df -h
Filesystem Size Used Avail Use% Mounted on
rpool/ROOT/s10x_u7wos_08
311G 18G 293G 6% /
swap 14G 384K 14G 1% /etc/svc/volatile
/usr/lib/libc/libc_hwcap1.so.1
311G 18G 293G 6% /lib/libc.so.1
swap 14G 52K 14G 1% /tmp

AVAILABLE DISK SELECTIONS:
0. c0d0 <DEFAULT cyl 60797 alt 2 hd 255 sec 63>
/pci@0,0/pci-ide@1f,2/ide@0/cmdk@0,0
1. c2d0 <Hitachi- JK1181YAHL0YK-0001-16777216.>
/pci@0,0/pci-ide@1f,5/ide@1/cmdk@0,0
Disk 1 above is the new disk I need to attach to expand my root pool (give /export/home some extra space).
If I try to attach my new disk to the pool
# zpool attach -f rpool c0d0s0 c2d0s0
cannot attach c2d0s0 to c0d0s0: new device must be a single disk
# uname -a
SunOS dsol1 5.10 Generic_139556-08 i86pc i386 i86pc Solaris
Any ideas?
