TL;DR: FreeNAS is only transferring at a few kbps making replacing disks almost impossible.
Hi All,
I got freenas running on a dedicated PC (4 core avoton, 32gb ram) and after struggling with a bunch of disks that prevented the OS from booting (no idea why, i just removed them) i got it to work and was extremely happy with it.
Then disaster struck.
i have a 11 disk volume (zfs, 2 parity disks), that i have built of whatever disks i had lying around, with the intent of replacing the disks progressively till all of them were the same size, brand and model.
I was replacing two of them when 3 disks simply disappeared.
Long story short, i recovered from that but resilvering is taking about 2 months for 20% (only 4tb volume).
I have decided to take the data out of that volume into a consumer grade NAS i had lying around, but i am having speeds of about a few kbps (when it doesn't simply fail).
I have another 4 disk volume and that one's performance also seems impacted even though all disks seems great.
The only things i see are large amounts of SMART errors on the console (i expected the disks to mark bad sectors and move on, but that doesn't seem to be the case).
The SMART errors are on the disks i was trying to replace in the first place.
The CPU is hardly used hovering on 4% usage on a single core.
The RAM is used to the maximum for the ARC cache and that seems to be fine.
This is not a "production" NAS... is a home NAS and i chose freenas as it seemed to be fairly simple to use (and wasn't wrong in that assessment till now).
One thing i have noticed, that might be nothing or might be relevant:
I create volumes of full disks or collections of disks and a single dataset per volume.
The volume size and dataset size doesn't match. The volume is always several GB larger than the available size for the dataset and couldn't find out why. (wasting huge amounts of space).
Any ideas of what i can do?
I am getting fairly desperate as i have tried everything i could think of and spent the last 2 months googling trying to find anything that might help.
Thanks in advance for your time and effort.
