Please. How do you shrink a RAID 1. Moving to a SSD drive

(1/3) > >>

Hi all,
I want to shrink a RAID 1 setup of my current drives to fit half the size of new SSD that I want to use.
The data on the RAID 1 is not a lot, less than 50Gig, maybe even 32 Gig.
The system is on metal. I originally installed clean with SME 8.? on a 500 gig hard drive to RAID 1, then replaced the drives with 1TB drives but never did expand the 500 to the full 1TB drives that are in RAID 1.

I have done some special adding of software along the way. So I would prefer the shrinking of the system to a new install.
I plan to use either 240 GIG or 480 GIG SSD drives now.

It seems worthy if possible to leave space on the SSD unallocated. I think they call this over provisioning a drive.
The information i have found on the forum seems scattered.
I have already done the backup of the files and used the web interface server-manager to backup the SME 8 server on the files I did not backup by simple copy from most the ibay folders.

Of course, I will remove a drive out of the RAID 1 to provide a safety net for what might go wrong.
I used the command line: sme raid=1 spaces=0   during the initial install of SME 8.
I would appreciate if somebody could lead me on how to reduce the system to something like a file system for a 120GIG drive.

So, in a nutshell I will.

Remove 1 of the 2 hard drives that are in RAID 1 and shelve it for backup.
Reduce/shrink the hard drive left in the machine to about 120 GIG.
Put in a 240Gig SSD drive.
Rebuild the RAID 1.
Remove the hard drive that I had reduced/shrunk.
Put in another 240Gig SSD drive.
Rebuild the RAID 1 to match that first SSD I put into service.
Basically this should leave me with half the SSD drives and I can grow the file system on the new SSD if necessary.

And just for what it worth. I do have SME 8 servers running on a couple of other SSD drives where they uses the whole SSD space from a new install.
I am using Samsung Pro 128 GIG and Intel 530 or 540 drives in the 180 or 240Gig sizes.
Thank you

Do a full backup, install new SME OS onto smaller drive, restore from backup.
Easiest approach IMO.

that is not quiet an answer.
There is a method to do as i asked.
When a lot of modifications have been done to a system and to a redo over may not bring the system to the same setup.
That is not the easiest approach. That is a beginners cop out.

Purvis, you're wrong
Janet have you the right answer
If you followed the SME way to make customization all you have to do is backup and restore
Usually I create my custom scripta in a dir which is comprised in backup and then link them if needed
Another way to achieve what you want is to install a single disk machine then use rsync, but you must know what and where
