One of the hard drives in my FreeNAS produced SMART errors last night:
From what I've read, this is pretty serious. Because of this, and because my (5x 3TB Seagate Constellation ES.2 Enterprise grade) drives are over 6 years old now, the time has come to replace them. I am thinking about buying 5x 6TB WD Red Pro, but nothings has been decided yet.
So now I need to backup my main pool to my set of new drives, but unfortunately I can only connect one set of drives at a time. So far I have connected an external 8TiB Seagate Archive drive, created a pool on it, and now I'm copying everything from my main pool to my archive pool.
But while this copy is running, I'm hoping there must be a better way, and that you guys can point me into the right direction. Because my method is very cumbersome; My main pool was my only pool until now, so besides my shares, it also contains jails and who knows what else. Verifying this backup after copying is a lot of work, and restoring everything back to a new pool probably even more. I could do this a second time, on a second disk, to easy my nerves on having everything on a single cheap disk for a while, but still it won't feel right when detaching my main pool on the old disks.
Is there an easy way to make a checksummed backup of my main pool on an external disk (twice), verify these backups, replace the main pool drives, restore the backup and verify it?
Code:
