Sun Microsystems X4540 manual ZFS Configuration, ZRM Configuration

5 Zpool Configuration Sun Microsystems, Inc.

The next step was adding two spare drives. Lastly, we checked the pool status and verified the availability of the zmanda pool for configuring ZFS.

RAIDZ2 is a natural choice for a backup server, which contains information vital to business operations. RAIDZ2 can survive up to two drive failures, regardless of whether they are due to corrupt data coming off the drives, a physical failure of the drives, or drives that are missing. With a suitably large number of disks, RAIDZ2 does not impose a greater penalty in capacity or performance than RAIDZ.

ZFS Configuration

The Zmanda Recovery Manager on the Sun Fire X4540 server Backup Server is configured to write backup images to a directory. For this sample installation, we chose to put the backup images for all backup sets on a single ZFS file system. On a system where multiple backup sets might be running simultaneously, it would be advantageous to have separate ZFS file systems and pools for each backup set, in order to spread reads and writes around the available disks.

Example of ZFS file system creation:

bash-3.00# zfs create -o mountpoint=/var/lib/mysql-zrm zmanda/zrm

bash-3.00# zfs list
NAME	USED	AVAIL	REFER	MOUNTPOINT
zmanda	203K	7.13T	49.0K	/zmanda
zmanda/zrm	49.0K 7.13T		49.0K	/var/lib/mysql-zrm

ZRM Configuration

The Sun Fire X4540 server is configured as a ZRM server with Zmanda Management Console (ZMC). To install ZRM and ZMC, follow these overall steps, which are explained in more detail in subsequent sections.

1.From the Zmanda Network web site (which requires registration), download the following:

●ZRM installer binary for Solaris 10 systems with Intel® or AMD OpteronTM processors:

ZRM-enterprise-2.2-installer-intel.bin

●Prerequisite packages: solaris-10-zrm-dependency-intel.tar.gz

2.Extract the prerequisite packages, solaris-10-zrm-dependency-intel.tar.gz , and install all the included packages.

3.Extract the binary package and run the Zmanda Rapid Installer to install ZRM.

4.After the installation is complete, the ZMC Welcome Page is displayed, and you can begin configuring backup sets.

Installing the Required Dependencies

The required dependency packages are provided in a compressed tar archive file, solaris-10-zrm-dependency- intel.tar.gz, that you can download from the Zmanda Network: http://network.zmanda.com
