I have an EX2 which had 2 x 2TB HDDs in RAID1, and I replaced them with 2 x 6TB in RAID1. I wanted to keep the data.
- Turned off, replace HDD #2
- Turned on, rebuilt the RAID1,
at this point everything seemed fine, I could see the data.
- Turn off, replace HDD #1
- Turn on, rebuilt the RAID1,
however, I only had 2TB capacity, & I was too quick in rebuilding the RAID 1, & only later discovered the “Expand Capacity” option, so I lost the data.
I had backed it up to an external USB hard drive, but I had also left the back set created & the drive b plugged in, so it ran the backup, creating a 0 data backup in the external HDD, too! No more data, except what’s on the previously removed 2 x 2TB HDDs.
I tried to just turning the EX2 off, removing the 2 x 6TB’s, then inserting the previous 2 x 2TB’s.
However the drives weren’t recognizable & it wanted to format & rebuild them, which I was afraid to do for fear of losing data there, again, too.
SO MY QUESTION IS:
Is there a way to rebuild the RAID 1 volume that already exists on those 2 x 2TB’s, so that I can then back data up externally, again.
Then, likewise, reinstall the 2 x 6TB’s with it’s own RAID 1 volume, and then transfer the data from the external HDD, to it?
Or, even, just rebuild the RAID 1 volume from the 2 x 2TB’s, using the “Expand Capacity” option
(will it guide me through inserting each 6TB drive in the process?).
Thanks for your help.
