Boot Pool Corrupted, Removed SSD still boots, but What Now? New to Trunas and servers in general!

So I set up Trunas yesterday and starting learning the ropes, excitedly spent all night last night playing around and learning, this morning I checked the system and had a report saying my internal SSD was Degraded, it came with the little Optiplex i turned into a small truenas machine to start learning some stuff about this realm and store data. I pulled the SSD out and put one in I had around the house and it says its too small to replace it, can I at least remove the degraded SSD from my boot pool to stop error message?

System Info: Dell Optiplex 7040 | I7 6700 | 16gb RAM | 250 gb m.2 | 240 gb Internal SSD “degraded” (Removed)| 128 gb Internal SSD (New) | 2 1TB HDD

Sorry, It still boots, but it also still gives me the error and says my storage pool is degaraded beacause of the ssd that i pulled out lol

I guess you had a mirrored boot pool?

IMHO there is no need to mirror boot.
I rather just insert a new disk, reimport the settings (that I backup after every single change).

im learning that this is actually the main practice haha do i need to reinstall with only the m.2 as the boot drive in order to get rid of the old one from my system?

I don’t know what you mean by “getting rid” of them. You can just boot into any installer and reformat the drives.

apologies


in truenas it still shows this, but i have physically pulled the “degrading” ssd out of the system, and its still throwing me the error message.

I really appreciate your time and expertise!

In a Mirror you cannot replace one part of the mirror with a smaller device. Bigger yes. Smaller no.

  • save your Truenas config file
  • reinstall Truenas on the smaller device alone without mirrors
  • load your config file

an easier solution would be to remove the device from the vdev (you can as its a mirror) and leave yourself with a single drive vdev for the boot pool

yes

I assumed he wants to use the smaller SSD as a boot device.

Thank you for this info! after further consideration I think it’d be better to reinstall using smaller internal SSD and use M.2 as a cache drive. This system is general is for me to have a small network storage for now and be able to learn and play before upgrading later, I appreciate everybody’s time in this! I’m so glad this community helps eachother out !

For anyone in a similar predicament, I suggest taking the time to unplug your hdds if using Dell Data Wipe, it will make the process much faster for wiping the SSDs, you live and you learn, ill wait ! lol Again thank you to everyone who took the time to reply to my post, true MVPs! :wink:

I would start without any “cache” drives. Most of the time this offers enough performance already and most of the time it will do more harm than good (when configured wrong and misunderstood).
