Hi.
My OMV 64bit is currently runnig with a 80GB USB Systemdrive an 6*2TB data-drives as raid5.
Now i have 5*3TB drives I want to use as raid5 data-drive.
My server has only 8 bays for the disks.
My plan A was to remove one 2tb drive from the raid, build a new raid5 with 3*3TB drives, copy the data from the old raid to the new, delete the old raid and grow the new raid with the 2 remaining 3TB drives.
Plan B was to replace the 2TB drives with the 3TB drives, one after the other, waiting for the rebuild each time and grow it after replacing the last disk .
For both plans I need to remove one 2TB drive from the raid5.
But how can I "shrink" my raid (and of course the filesystem (ext4) before) ?
In the webgui I only can grow the raid.
And what do you think ist the best way ?
I think plan B will keep my filesystem, shared folders and smb shares.
Thx.
