I finally want to try Rockstor instead of OMV as my NAS System.
As i have 4 different sized HDDs i want to make one single Datapool without any Raid Function.
But how to migrate my Data?
As non of my HDDs is full i´ve thought about copying some Data from one of the bigger Drives to an external drive and create a pool with this in rockstor. After Copying the Data via Windows Machine from the external drive back to the HDD i want to take the next HDD and Copy the Data from Windows to Rockstor. After Data is copied i want to add the empty HDD to the Storagepool. This procedure shoudl be done with all 4 drives.
Do you think this is possible or do you know an easier way?
Just for your info - it works
I should assume that this is the only “sane” way to do it. There are tricks you can convert in place from etx4, but I would strongly discourage that.
Just FYI, beauty of btrfs is that you can have different size disk and still use all of available space in RAID1 btrfs will keep 2 copies on two different disks, and will attempt to mix disks in the fashion that will use all available space that is there.
Welcome to rockstor / btrfs crazy world
Ok… After some trying I’ve found the most comfortable solution in mounting the old ext 4 drive and copying the data using midnight commander to the new btrfs formatted drive
Just for future reference - when copying a large data set and NOT using midnight commander it’s always worth checking flags for copy, for example:
cp -xar source/* destination/
should copy files WITH all attributes / access right / ownership etc
