Upgrading Really Old FreeNAS Setup

[JonnyAlpha]

Hi,

I have a really old FreeNAS setup and talked about upgrading it here. I never managed to get around to upgrading it and occasionally fire it up and access the data.
Having been off work recovering from an Op and started to use it again in an attempt to sort old all of my old (but much still required) data.

It's been working OK, but I know I do need to seriously look at my data storage solution and upgrade.

Today I went to fire it up and got the dreaded - your pool is in a degraded state, one drive is not being recognised - or something like that.
With regards to fixing this, where is the best place to post questions about an old system?

WIth regards to replacement options, I'll start looking at the info on these Forums, but not sure which path I will go - ready made NAS, Raspberry Pi NAS or PC based NAS? It's been a long time since I researched any of this so I'll have to start from the beginning again.

First stop I think is to get a 4TB Seagate or WD USB HDD and backup what I have on the FreeNAS box!

This looks like you are the one and lonely who has a case to post his thread under "FreeNAS (Legacy Software Releases)" (are you still on FreeNAS 8.3.0?) whereas just about everybody else ends up posting under the legacy section while they really should have scrolled down to the "TrueNAS CORE" or "SCALE" sections as appropiate. Congratulations!

An external backup is a very good idea.
Posting the output of zpool status -v and smartctl -a /dev/adaN (replacing 'adaN' by whatever moniker the failing drive goes by) would help assessing the situation. Please use CODE tags (</>).

As for the replacement, it depends how much you're willing to spend, in money and in time to manage a self-made NAS. A PC-based NAS running TrueNAS has the benefit that you could just plug in your remaining drives—but they probably all need to be ultimately replaced due to age. Do you, by any chance, have some unused-but-not-desperately-old PC lying around?

Not sure how you quote a post on this forum so I just replied.

Anyway, before I switched the NAS on today I took the cabinet side off, low and behold the power cable for one of the HDDs appears to have come undone? No idea how that may have happened.
Just booted up but it's still showing a yellow alert.

To quote a post, click the "Reply" button at the end of it.

If it was "just" a dislodged power cable (vibrations?), maybe you're fine. The critical parts in SMART reports would be #5 and #197, pending and reallocated (bad) sectors. (Best log in via ssh to copy-paste from the terminla output; the GUI terminal is broken.) And you should be running regular SMART tests.
I suggest a scrub, zpool clear if it returns fine to clear the lone checksum error; and long SMART tests on all drives.

Hmm, I ssh all the time into my Raspberry Pi's but never into the FreeNAS. What / how do I find the hostname or whatever its called that goes in front of the @<ip addrss>?
I did a

Code:

zpool clear

and think I ran a scrub from the terminal

Code:

scrub FreeNAS

, the warning was not there when I rebooted.

P.S. Sorry these probably aren't written here correctly as I had to search how to.

SSH usually works with user@hostname:port; ie root@truenas.local:22. the port is usually required if you don't use the default (22) one.
