Defrag - Find out how long?
Being new to ReadyNAS there were various things I wanted to know. One of these was about the Defrag process and how long it takes to run. Having trawled through the forums, one thing is apparent. ...
I did it again...
System ..... OS ....... RAID .... Disks ......... Total ........ Used ......... Defrag time ..... Comments
Pro-6 ....... 6.2.3 ... 5 ......... 3 of 3 TB .... 5.45 TiB .... 2.14 TiB ..... 55 Mins ........... T1773, with snapshots

Hi, so I've done the defrag today after doing the balance on my system A (as per another balance thread)
System ..... OS ....... RAID .... Disks ......... Total ........ Used ......... Balance time ... Comments
A RN3220 ...... 6..2.4 .... 6.... 6 of 3 TB ...... 10.8 TB ... 5.4TB TB ..... 2 hours 20 mins....... First time running it, no VMs online so don't know impact
B RN3220 ...... 6..2.4 .... 10.... 6 of 3 TB ...... 8 TB ... 7 TB ..... 20 min. ........ Never done before
B RN3220 ...... 6..2.4 .... 10.... 6 of 3 TB ...... 8 TB ... 7 TB ..... 20 min. ........ Weekly schedule
We're due to upgrade the OS this week on both systems.
(I know this isn't a request area) I think it would be really useful if there was either a predicted or progress bar for defrag - unless I'm missing where it is?

I've raised this myself with Netgear development.
btrfs itself provides progress information for scrub and balance. But defrag with btrfs is done file by file. So inserting progress information has to be done by the application. There is some concern that doing so would seriously increase the defrag running time.
It would still be helpful if there was at least a "defrag running" indication, or a display of the most recently defragged file.
