ZFS file systems are an important feature of Solaris 10, and instance configurations can be more capacity-aware of ZFS file system configurations.

One, Solaris Disk basics

1. Disk View method

# format
0. c0d1 <xxx cyl 6524 alt 2 HD 255 sec 63>
1. c1t0d0 <vmware,-vmwarevirtuals-1.0 cyl 1302 alt 2 HD 255 sec 63>
2. c1t1d0 <vmware,-vmware Virtual s-1.0-10.00gb>
3. c1t2d0 <vmware,-vmware Virtual-1.0 cyl 1303 alt 2 HD 255 sec 63>
4. c1t3d0 <vmware,-vmware Virtual s-1.0-10.00gb>

Specify disk (enter its number): 3
# Quit Quit

2. Disk capacity View method


Second, ZFS file system configuration

1. Create Zpool (RAID0)

Create a ZFS file system named a

# zpool create-f c1t0d0 c1t1d0 c1t2d0

' A ' successfully created, but with no redundancy; Failure of one
Device would cause loss of the pool

# Tip Three disk does not do redundancy, bad a disk is all bad.
# The hard disk that joins pool is the whole disk, which makes it easy for the pool to manage the hard disk.
# because a UFS has been used before the disk that joins the pool, the-f option is required during the creation process to ignore the UFS file format to force the hard drive into the pool.

Expansion of Pool

# Zpool Add-c1t3d0

-N Simulation results after the expansion
-F Enforcement

# Zpool Add-n-F-c1t3d0
Would update ' the following configuration:

2. Create mirrored pool, usually two pieces of disk size (RAID1)
# zpool Create-f Mirror c1t0d0 c1t1d0

3. Create Mirror Pool (RAID 10)
# zpool Create-f Mirror c1t0d0 c1t1d0 Mirror c1t2d0 c1t3d0

4. Create Raidz Zpool (RAID5)
# Zpool Create a raidz2 c1t0d0 c1t1d0 c1t2d0 c1t3d0

5. Create Raidz Zpool and add a hot spare
# Zpool Create raidz2 c1t0d0 c1t1d0 c1t2d0 Spare c1t3d0

(1) The addition of hot spare plate
# Zpool Add-Spare c1t3d0

(2) The removal of hot spare plate
# Zpool Remove-c1t3d0

6. Mirroring and splitting mirrors

(1) Create mirror
If you create a zpool, the physical disk is a single, you can mirror it, and the command format is
# Zpool Attach the new disk of the old disk

# Zpool Attach c1t0d0 c1t1d0

(2) split mirror (contrary to the image process because of impact data)
# Zpool Detach, c1t1d0

7. Delete Zpool

# Zpool Destroy Poolname
# Zpool Destroy-f poolname

8. View Zpool list, status

# Zpool List
# Zpool status [-x][-v]
# The purpose of the checksum
# Zpool Scrub poolname

# The purpose of the checksum, which typically takes a long time,
# Zpool Status View the verification progress, preferably in the hardware problems, after the solution is verified to ensure that everything is normal.

9. Create a file system

Classic usage examples

1) Create U01 file system
# ZFS Create first/u01

2) mount to the/u01 directory, not mount can also be used directly
# ZFS Set mountpoint=/u01 first/u01

3) Set disk quotas
# ZFS Set quota=20g first/u01

Creating snapshots

1) Create snapshots
# ZFS Snapshot First/u01@ok

2) Restore the snapshot
# ZFS Rollback First/u01@ok

3 Delete snapshots and ZFS file systems

Note: When deleting a u01 snapshot, the Add-r parameter is deleted with the same origin and used with caution.
# ZFS Destroy-r First/u01@ok

To create a ZFS clone:

Create a ZFS directory from a snapshot

# ZFS Clone First/u01@ok First/bak
