hyper-v to esx conversion

Posted on by — No Comments ↓

V2V cold clone process for SBS / exchange / sql / DC’s etc…..    (works in vSphere)

Steps to convert from hyper-v guest to vmware guest

  • Remove hyper-v integrated services while hyper-v guest is running. (if possible)
  • Note down NIC networking details first
  • Clean shutdown hyper-v guest
  • Use StarWind Converter (free) to convert VHD to “dynamically growing VMware” image and use “IDE” as type. Note “SCSI” does NOT work if you have not got the LSI / BUS drivers in the source image, just use the default options – dynamic vmware and IDE.
  • Create VMware guest shell (virtual machine equivalent to hyper-v specs but without the disks) – remove all hard drives, iscsi controller should also disappear.
  • Upload the VMDK to same data store as virtual machine and attach to the virtual guest in the right order. They should be detected as “IDE”
  • Start new vmware guest
  • If you could not remove integrated services (i.e. hot clone), then you MUST disable hyper-v services immediately.
  • Install vmware tools – reboot
  • Remove hidden NIC and other orphaned devices, and reconfigure network card as per original.
  • Windows may need to be re-activated – do this.

Note : converting a machine to use an IDE controller will limit its performance!

opensolaris v134 – CIFS has gone walkies

Errr, I cant find the CIFS service in the 134 build.

I know it was renamed to as per below but still cant see it anywhere?

> system/file-system/smb (was SUNWsmbfs*)
> service/file-system/smb (was SUNWsmbs*)

Anyone have any ideas?

pkg search *smb gets me these… but i cant install them.

require depend service/file-system/[email protected] pkg:/[email protected]
require depend service/file-system/[email protected] pkg:/storage/[email protected]
require depend service/file-system/[email protected] pkg:/system/security/[email protected]
require depend service/file-system/[email protected] pkg:/storage/[email protected]
require depend system/file-system/[email protected] pkg:/[email protected]
require depend system/file-system/[email protected] pkg:/storage/[email protected]
require depend system/file-system/[email protected] pkg:/[email protected]

pkg install system/file-system/smb

No updates necessary for this image.

pkg install service/file-system/smb

Creating Plan
pkg: The following pattern(s) did not match any packages in the current catalog.
Try relaxing the pattern, refreshing and/or examining the catalogs:
service/file-system/smb

zfs – now has dedup!

Posted on by — No Comments ↓

Cool. zfs as of version 21 has deduplication built in. And thats the good dedup – synchronous dedup. i.e. deduped on the fly!

How easy is it to turn on? – very!

Once you have upgraded your zpool to 21 or above you can run the following command at the pool level and deduplication will be over all your data from that point onwards.

zpool set dedup=on tank

Done

Note : Watch your performance, it will drop like a rock if you do not have enough ram for your dedup tables. Do some tests after enabling this feature.

iometer testing

The following is some notes i have around the parameters i usually use during testing. There is a good document at ixbt labs on the various tests and settings….

For a 1GB test set the sectors to : 2048000

Typical benchmarks; (which you will need to add)

128K 100% Read – Sequential

128K 100% Write – Sequential

Remember to bump the workers up to 5 or so. You can set the mixes across all the workers if you select the PC object.
