This is probably a popular question but I can't seem to locate an answer.  I've begun moving my data from reiserfs to xfs, and have my first disk copying over now via rsync.

 

I have rsync running via screen on unraid copying from disk 4 to disk 8, Both are 2TB drives, but the source drive only has about 1TB of data  on it.

 

Also, if it matters, both HDs are connected to a Sas 8port PCI card.  So data transfer if moving through there.

 

Any general thoughts on how long till it should be done?    4hrs, a full day, 2 days, etc?   I'm just trying to get a general idea when to check back and see if its done.

What matters more is what are you copying. A few GB sized files or a hundred thousand small jpg. Are you copying while parity protected?

 

One TB will take about 4hrs if your copy speed is 100mb/sec. I doub't you are going that fast.

I recently converted my 2TB drives to XFS.  I disabled the parity disk for faster transfer speed and used rsync to copy disk-to-disk.  It took me 10.5 hours per disk with mostly large files.  An average of 4hrs per TB.  Keeping parity enabled would likely take 2-3 times longer.

 

I had the same question as you after the fact. Here was my thread:

Thanks guys,

 

I do have parity enabled so may be a little slower.  And I'm transferring larger 1 - 4GB Movies and TVShows.  The Unraid Dashboard shows the utilization of each disk as well which helps in giving an idea on the progress. So I'm about  4 hours in and about half way there.  So hopefully another 4+ hours to complete and can then start in on the next drive.
