Hi Folks,
i have 2 storage servers running open-e that were brought at different times, i want to wipe everything from the one and replicate the other is this something that can be done? or do you have to wipe both boxes to configure this?
thanks all

This can be done:

hi gr,
this talks about setting up a new iscsi volume group and this is why i thought it will wipe my current setup as all my disk space is currently used by the current volume group?
no need to wipe or create new volumes, just enable the replication on each one you need to replicate.
hiya when i try and create this on the source it says i dont have enough free space as i created one big volume at the start is it possible to auto resize this somewhere without losing my data?
Cheers

Enabling replication for volume really creates a small attached volume to store metadata on it and it requires 128MB of space for each 4TB of volume. I assume you do not have any more space left in your Volume Group?
hiya Pi
thats correct this was created before we brought the second dss box is there anyway of altering this realtime? without losing data?
From the “Volume Manager” function you can add a disk volume to a new LV,
or increase the size of existing LVs (you cannot decrease LV size).
To set the needed LV size just use the scrollbar.
On the right side of it you will find a counter of available space.
This function can be also used to reserve disk space for swap, snapshots, system and replication.
Also if your system has a 4GB of SWAP, you can delete it to free some space.
If it is supposed to be a long-term solution the best would be to add another HDD to your array if your RAID supports expansion (adding space without wiping out and rebuilding whole array)
if i delete the swap what happens? can i recreate it but smaller?
SWAP created by the system( not controled by user ), in general we create an option to delete it, so you can use it in critical issues or when you need a space.
We recommend you to add extra storage so you can have more free space if you still need it.
hi Al, when i do that it auto recrate the swap and doesnt delete it? do i need all my VMS shutdown?
Hi Guys,
so ive got it replicating now, if in the event of one of my storage boxes falling over how do you go about switching it onto the other one? im using citrix xenserver
Cheers

For that you need to configure and start automatic failover.

Do you mean you want to delete all data on the Primary and Secondary server?
Well, you can stop the replication, and then you can delete all your VG from Console mode, press CTRL + ALT + X , select "Delete content of units" , select the proper Volume Group to delete, then the system will reboot.
* Please put in your mind that will delete all your data, so if there are any important data you should backup it first before you do this steps, as we are not responsible for your data if you delete it.
