Booted back in and its all up and running. You have no idea how grateful I am fort the help. What is the best way, without spending money I don’t have, to give me some protection from this sort of thing happening again. With a jbod is there anyway to have parity drives?
You need to backup the data you really care about on that pool asap. It’s beyond saving and you need to start again but please just ask for help on the forums regarding pool config.
Years ago I ran a 2 disc raid0 and realised it was risky. I know see that what I’m doing is running a 8 disc stripe. It never occurred to me until now.
Even if the discs were empty is there anyway to set it up with parity drives. I don’t really understand about width and so on.
It was 250GB. I had to go into the system to drain the cmos after the original shutdown and must have moved the usb cable for the drive so it didn’t register.
Based on the drives you have available I would take the two 4.55TiB drives and make a mirror this would essentially give you 4.55TiB of space but a least some redundancy. The other drives are fairly pointless tbh. You can always replace these 4.55TiB drives one at a time with bigger drives to give you more space and even add additional mirrors to the pool (these are called vdevs) to expand the pool further.
You are running an 8-wide RAID0…
You could turn it into a redundant array by “extending” each and every single drive vdev into a 2-way mirror. That requires 8 drives, each at least as large as the drive it will be paired with.
But that’s more trouble than if worth for sub-TB hard drives… (How old are these things?)
But what you really want for a media collection is a raidz1 or raidz2 (preferably Z2) parity array (RAID5, RAID6), which requires at least three or at least four CMR hard drives, larger and preferably all of similar sizes.
4.55 TiB = 5 TB
Is this a 2.5" HDD? If so, it is SMR and essentially useless for use with ZFS.
The other drives are indeed, so small as to be pointless, but I suspect a collection of old laptop hard drives where TrueNAS really wants 3.5" HDDs of the CMR kind.
Most of the drives are just old laptop drives but the two 5TB drives were external drives. Originally I needed some way to watch media on a gaming laptop and set up a NAS using old drives I had lying around.
I got ill some years ago and can’t work so my income is less than £4000 year (under £100 week) so can’t afford to buy multiple drives to setup a decent NAS. I bought the two 5TBs from Amazon as they were on interest free credit and just added them about year apart (bought 1 then year later bought the other).
I’m just really limited with what I can do and the cost of living increases have exacerbated the problems.
One thing I picked up on immediately was “USB”. Hopefully this is not how all your drives are connected. It is not a reliable method of connection but I understand that you do what you can afford to do.
@Johnny_Fartpants really helped you out, very clear instructions. When I started reading this thread I was thinking the drive failed. Luck was on your side.
There’s four usb and four internal sata. Unfortunately the internal sata ones are all tiny 150GB or thereabouts. The two big 5TB are external usb. As I said I set it all up with what I had lying around and added what I could later. I just don’t have money to improve the situation. Yes Johnny_fartpants really helped save my bacon.
