Solaris

Solaris is an operating system.

SVM

Solaris Volume Manager (formerly Solstice DiskSuite) is a software RAID package for Solaris.

• display arrays:

# metastat -c
d8               m   19GB d6 d7
    d6           s   19GB c0t2d0s1 c0t3d0s1
    d7           s   19GB c0t4d0s1 c0t5d0s1
d2               m  380GB d0 d1 (resync-46%)
    d0           s  380GB c0t0d0s1 c0t1d0s7 c0t2d0s0
    d1           s  380GB c0t3d0s0 c0t4d0s0 c0t5d0s0
d5               m  8.5GB d3 d4
    d3           s  8.5GB c0t1d0s0
    d4           s  9.2GB c0t0d0s0

(leave off -c for more detailed information)

• create a new raid-0 array named d0 on c0t0d0s0 and c0t1d0s0:

# metainit -f d0 1 2 c0t0d0s0 c0t1d0s0

• create a new raid-1 array named d2 from d0 and d1:

# metainit -f d2 -m d0
# metattach d2 d1

(RAID-10 is accomplished by striping mirrors, i.e. it looks like RAID 0+1, except it's not, really)

Services

Solaris uses Service Management Facility for services.

# svcs -a                    (display all services)

legacy_run     16:57:12 lrc:/etc/rcS_d/S50sk98sol

Misc differences from Linux

• /etc/vfstab, not /etc/fstab
• use share to share NFS filesystems:

share -F nfs -orw=10.0.0.1 /export/homefs

• df looks odd. use df -h
