Hard drive upgrade question

[rayearth2000]

Hi! I been using FreeNas 3 to 4 year, now I have big question, my 2x4TB mirror hard driver is full ( family picture & file sys) , and my 5TB workspace is almost 70% use, planing to brought 3x10TB hard drive to replace it, is there any other efficiency way to do file transfer, before I use stupid way (copy and paste) for 1TB, but file became more and more...

If I understand you correctly you want to replace each drive on your system with new 10TB drives. It sounds like you have a single drive as a stripe (5TB drive with no redundancy) and this data has to be manually copied to the new drive (manually being either you use a CP command or use some other method). I would connect the new drive to the system, create the ne pool of one drive, then copy the data over. Look up the FreeBSD command "cp" and you will be able to copy everything including recursive directories with one command.

The two 4TB mirrored drives can be replaced one at a time (follow the user guide) and after the first drive has been resilvered, the second drive can be replaced and it will resilver. Resilvering can take a long time, if you do have 4TB of data then you could be looking at over a day because photos are lots of small files and small files take a long time to copy.

If it's possible I would backup your important files to another location if not already done. If you mess up the drive replacement then you could lose your photos. And don't be in a rush.

The better way to go might be to make a single RAIDZ1 vdev/pool out of the three 10TB drives, if your system can handle attaching three additional drives, and then move all your data to the new pool. If you could add a fourth 10TB drive and create a RAIDZ2, that would be better from a redundancy point of view.

Good Luck!

The 5TB unit could be mirrored to the 10TB, then replace the 5TB drive to make a mirror, or split the mirror and remove the 5TB
