Citrix XenServer 5.5 Update 1

Category : Citrix, Windows 2008 R2, Windows 7, XenServer 5.5

Tags: , , ,

Citrix release today the first update for XenServer 5.5 :

Changes included in this update
LVHD Snapshots
When LVHD snapshots are deleted, disk space is reclaimed by freeing unused snapshot data. This is provided automatically by XenServer while VMs continue to run. However, there is a known limitation in the 5.5 implementation of this feature: when all snapshots are deleted for a given VM?s disks, some disk space allocated to these snapshots may remain. To address this limitation, Update 1 includes an ‘Off-line Coalesce’ tool that can reclaim all disk space previously allocated to deleted snapshots while the VM is temporarily set offline. The Off-line Coalesce tool and its use are described in full in an associated KB article: CTX123400.

XenCenter Improvements
CA-30569, CA-32164, CA-30200

Fixed various ‘Application Errors’ in XenCenter.

 

CA-32241

XenCenter saved searches are now visible under ‘Apply Saved search’ and ‘Delete saved search’ options.

 

CA-33918

Big improvements to XenCenter performance when connecting to multiple pools.

 

 

Storage
CA-30577

Snapshot errors after upgrade from 5.0 to 5.5. Previously released as hotfix XS55E001 and documented in KB article CTX122142.

 

CA-24607

When multipathing is disabled, then this information is now correctly displayed in XenCenter.

Category : Citrix, XenServer 5.5

Tags: , , , , , ,

Now the final release of XenServer 5.5 is available for download ( https://www.citrix.com/English/ss/downloads/results.asp?productID=683148 with you MyCitrix account ) I had to upgrade my XenServer 5.5 beta 1 to this new release.

My first step was to download all iso files and XenCenter 5.5, the I began with and upgrade of XenCenter, and the problem I had once everything was install, that didn’t work… The XenCenter console disn’t show up, the I choose to uninstall everything and delete the folder in “c:\program files\Citrix\XenCenter” and proceed the setup again. It did the trick.

Adding local storage to XenServer 5.5

Category : Citrix, XenServer, XenServer 5, XenServer 5.5

Tags: , , , , , ,

BE AWARE !! To follow instructions in this blog post you have to know linux shell and XenServer command line usage. You can wipe data if you don’t understand what you’re trying to do. Try in a TEST environment before making any change in production.

Today I had to add two 500Gb SATAu hard drive to my XenServer. Plug this two hot plug drive in this Dell 2950 III was the easy part, configure the new RAID1 in the Perc 6i controller wasn’t so easy… This bios is very annoying and after 2 hours we found the good menu and where to create the new volume…

Once this step done, and after 16Gb of memory more, XenServer started without any problem, the drive wasn’t available through the XenCenter so I though I had to mount it or something like that.

So here comes the few steps to add a local storage to your XenServer 5.5 :

Type : fdisk -l

you’ll see the list of all volumes and hard drives, then :

Type : pvcreate /dev/sdb

sdb is my new volume

and then to configure it as a local storage :

Type : xe sr-create type=lvm content-type=user device-config:device=/dev/disk/by-id/scsi-SATA_ST3320620AS_5QF7QZZL name-label=”LOCAL SR”

scsi-SATA_ST3320620AS_5QF7QZZL is the name of my volume, you’ll have to change this value with your own, and name-label is the name you want to give to your local storage.

and this is it !

Remark : If your XenServer is a pool, you need to put it off, follow above steps and put back the XenServer in your pool.
