i think this question may attrach more attention in the hardware TA...

<div class="content wysiwyg-content">
All,<br />
&nbsp;I'm currently setting up MySQL 5.x Cluster on Redhat 4.0. The hardware configuration looks like this:<br />
<br />
2x Dell Poweredge 1850<br />
1x Dell PowerVault 220S<br />
<br />
The hardware is set in &quot;cluster&quot; mode per Dell but the OS is *NOT* clustered. I opted to have MySQL do the clustering as opposed to clustering the entire shooting match.<br />
<br />
Here's my question: In the OS the mount point for the Powervault is /data and is visible by either node in this configuration. Does the MySQL cluster process prevent concurrent writing to that parition in HA mode?<br />
<br />
The documentation regarding this was lacking so any insight would be useful.<br />
<br />
Thanks.

All,
 I'm currently setting up MySQL 5.x Cluster on Redhat 4.0. The hardware configuration looks like this:

2x Dell Poweredge 1850
1x Dell PowerVault 220S

The hardware is set in "cluster" mode per Dell but the OS is *NOT* clustered. I opted to have MySQL do the clustering as opposed to clustering the entire shooting match.

Here's my question: In the OS the mount point for the Powervault is /data and is visible by either node in this configuration. Does the MySQL cluster process prevent concurrent writing to that parition in HA mode?

The documentation regarding this was lacking so any insight would be useful.

Thanks.

MySQL Cluster - Shared Disk Configuration

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.

Storage Software

MySQL is an open source, relational database management system that runs as a server providing multi-user access to a number of databases. Acquired by Oracle in 2009, it is frequently used in combination with PHP installations, powering most of the WordPress installations.
