DRD clone mirrored root_dg to one disk
Hi guys,
i have this scenario:
rootdg with 4 disk:
dm disk7_p2 disk7_p2 auto 1024 92825504 -
dm rootdisk02 disk6_p2 auto 1024 62551968 -
dm rootmir1 disk9_p2 auto 1024 62550944 -
dm rootmir2 disk10_p2 auto 1024 92825504 -
The 62 Gb disks are primary and mirrored of O.S. system
The 92 Gb disk are a secondary Swap.
Now i have a 67 Gb disk for clone a rootdg but the error is :
drd The total volume sizes in disk group: "drd_rootdg" exceed the available capacity by 57243Mb.
I have any questions :
Can i clone a DG or VG mirrored in one clone disk without mirror ?
For a Dg/Vg mirrored what size disk i must use, the total space disk (primary disk+mirrored disk) or also the size of one disk (primary)?
Exist a option for exclude a mirror for a clone ?
In the count of disk for a clone i must count a SECONDARY SWAP ?
In this situation if i want use one also disk , what size of disk i must use?
What is a clone best practice for this scenario ?
Thanks a lot

Re: DRD clone mirrored root_dg to one disk
Never done this with VxVM, but a clone is always unmirrored. It is just a clone of the OS. Looks like you need more space even for the unmirrored clone.
Hope this helps!
Regards
Torsten.

Re: DRD clone mirrored root_dg to one disk
The clone will be mirrored if you specify "-x mirror_disk" only.
Hope this helps!

Torsten.

Re: DRD clone mirrored root_dg to one disk
This is was I told you.
By default you create a non-mirrored clone, even from a mirrored disk.
Hope this helps!

Torsten.

Re: DRD clone mirrored root_dg to one disk
This is what the manual says:
"...The target's physical disk need not be as lar ge as the disk allocated for the root group, as long
as there is enough space for a copy of each logical volume in the root group. However , the disk
needs to be lar ger than the used space in each logical volume because each logical volume will
be created with the number of physical extents currently allocated to the corresponding root group
logical volume ..."
You can use a single target only.
Maybe you can delete the secondary swap during the cloning?
Hope this helps!
Regards
Torsten.

Re: DRD clone mirrored root_dg to one disk
Ok i have used one disk of 200 Gb. Now the space is no longer a problem.
/opt/drd/bin/drd clone -vv -p -x overwrite=true -t /dev/disk/disk249
Now i have another error :
* The command "vxrootmir" is being invoked. This step will take some time......
ERROR: Clone file system creation fails.
- Creating the target file systems fails.
- Command "/usr/lib/vxvm/bin/vxbrk_rootmir" fails. The entire output from the command is given below:

Re: DRD clone mirrored root_dg to one disk
I think your issue is now here:
dm disk7_p2 disk7_p2 auto 1024 92825504 -
dm rootdisk02 disk6_p2 auto 1024 62551968 -
dm rootmir1 disk9_p2 auto 1024 62550944 -
dm rootmir2 disk10_p2 auto 1024 92825504 -
VxVM vxbrk_rootmir ERROR V-5-2-4943 Some disks in rootdg disk group do not contain all boot volumes
Hopefully somebody with good VxVM knowledge will find this thread ...
Hope this helps!
Regards
Torsten.
