New ghettoVCB maintenance release

03.15.2011 by William Lam // 1 Comment

Check out the latest update to ghettoVCB. This release is primarily focused on providing more detailed information both before and during the backup process. In the past, there were certain caveats that may cause a VM/VMDK to not back up and required multiple iterations through a thread to resolve the issue. Hopefully, now with the additional information, it will help users quickly identify potential issues in their environment that may impact their backups and ease in the troubleshooting process

Here is a list of what's new:

Enhancements:

  • Enhanced "dryrun" details including configuration and/or VMDK(s) issues
    • Warning messages about physical RDM and Independent VMDK(s)
    • Warning messages about VMs with existing snapshots
  • New storage debugging details
    • Datastore details both pre and post backups
    • Datstore blocksize miss-match warnings
  • Quick email status summary is now included in the title of the email, this allows a user to quickly verify whether a backup was successful or had complete/partial failure without having to go through the logs.
  • Updated ghettoVCB documentation
  • ghettoVCB going forward will now be version tracked via github and previous releases will also be available for download

Fixes:

  • Updated absolute sym link path for RSYNC_LINK variable to relative path
  • Enhanced logging and details on warning/error messages

Here's a quick look at some of the details exposed during the "dryrun" process to help identify which VMs may have issues before the backup even take place:

  
Big thanks to Alain Spineux and his contributions to the ghettoVCB script and helping with debugging and testing.

Hope you enjoy this maintenance release, if you have any issues or feedback, please post them in the ghettoVCB group.

Ghetto Groups

01.20.2011 by William Lam // 1 Comment

Back in December, VMware upgraded their VMTN (VMware Technology Network) forum software Jive and introduced a completely new layout of the forums that would hopefully enhance the user experience. Though it brought many new features, it also brought on several new issues. The one bug that affected me was the incorrect conversion of the ghettoVCB document, because the conversion was unsuccessful it was decided to be left alone until the issue could be resolved. If you visited the document, it would display a "Forbidden" error message. Unfortunately due to the time it took to resolve, even Google cache started to get stale and stopped serving the cached contents.

Luckily, with the help of Alex Maier (VMTN Community Manager) and her team, she was able to get the ball rolling and got the fix tested and rolled out to production. The ghettoVCB document is once again alive and hopefully in no time it will be returned as the first search result on various search engines.

Going through the pain of receiving dozen of emails, private messages, tweets, etc. per week regarding the issue, I came to realize that VMTN document itself was not the right medium to host both content and user discussions. As it stands today, there are over 1,100+ comments which is pretty significant and managing and keeping up with the conversations is a pretty daunting task. I enjoy the feedback that community provides and the collaboration that takes place and I realize that this can be solved by using the new Groups feature.

To be honest, I did not spend much time looking at Groups when the VMTN software was upgraded, but now that the ghettoVCB document has been fixed, I realized this would fit this need perfectly. With the help of categories users can now post their feedback, discussions/issues and feature request and it can be easier consumed by both new users and myself. Starting today, I will have the following groups based on the top 5 most popular and active scripts:

ghettoVCB Group
ghettoVCBg2 Group
vmwarevSphereHealthCheck Group
vmwarevSphereSecurityHardening Group
ghettoUPSHostShutdown Group 

I have also disabled any new comments on these VMTN documents and will ask that all new comments be re-directed to respective VMware Groups. I'm currently working with Alex to see if there is an easy way to convert the existing comments into a document and attached that as a download to help minimize the complexity of the document. In the worse case, the comments will be left alone as read-only as I think the discussion that currently exists are invaluable. All other VMTN documents that I maintain in the vGhetto Repository will continue to use comments and depending on how well the groups go, I may migrate those over as well.

I hope these new groups will be beneficial for everyone and I am looking forward to the collaboration. Thanks for your support and please help spread the word!

Script: ghettoVCB Email Support (Experimental Support)

07.28.2010 by William Lam // 14 Comments

Check out the latest update to ghettoVCB which now support backup logs to be emailed upon competition. This feature is in experimental support and require the availability of nc (netcat) utility which is included in ESX(i) 4.0+. One can utilize netcat for variety of networking tasks, including communicating to an email server. The reason this feature is in experimental support is it may not be compatible with all email servers. The email functionality has been tested against a default installation of Postfix and is provided as-is.

For more details, please take a look at the ghettoVCB documentation.
