hi i am running truenas core 13.3.u1.2
i am having some problems with my drives they are all zfs
bootpool is ok but my other 3 pools have degrade each pool has 2 drives
have this problem: Device: /dev/ada0, 8 Offline uncorrectable sectors.
(i guess this means that ada0 and ada 8 is offline)
i would like to copy all files from the current drives that are working to another nas like omv7.x formated as ext4 using rsync can i do this ?
then replace all bad drives i don’t want to make new pools just replace drives per pool
This means just what it states: The drive that is currently ada0 has 8 bad sectors which have been retired from use by the drive’s firmware; you can check with smartctl -x /dev/ada0 in a SSH session.
Yes.
But the easier solution is to replace the drive in place. Install a new drive, go to Storage>Pool>Status, select drive an click Replace. Look up the documentation for more details if neede, but preferably do not offline or remove the old drive until the replacement is done to preserve redundancy.
hi i had shut down my server for some time(1+month) to work on some other projects then forgot about it. 1 week ago bought a couple of drives both 6tb i removed the drives from system without detaching from pool first, but remembered that i should have detached from pool first so i reconnected cable to bad drives detached them from pool , now my new drives(oops made a mistake buying correct size drive 1 should have 4tb and the other 6tb)
so until i get new 4tb drive will have to use 6tb drive or should i just make a new pool with both new 6tb drives and transfer data from old pool to new pool (rsync or something)?
i also need a third 6tb drive for another pool any advise please
You need to post details on your system. Run the following in a shell window (CLI) and post the results back using Preformattted Text (</>) or Ctrl+e
This will at least tell us your pool setup and VDEVs
Take a look at ‘Details’ below my post and that is the kind of details we need to see for the hardware, OS and pools.

It looks like you wrote you had three pools, each was a mirrored pair, in your first post.
This is what looks to be showing currently
boot-pool is two mirrored drives ada3 & ada4.
containerjail single drive?
mediapool1 mirror of ada2 & ada6
second4tb is ada0
storage2 single disk
Nothing is showing DEGRADED status. I think you detached the second mirror(s) drives from your pools instead of doing the replacement steps.
Did you have any spare disk ports before you detatched the troublesome drives? What are your pool setups supposed to be. Please list the drive sizes. What are you trying to do? Are you just replacing the bad drives with new one or are you also trying to grow the pool size? You can replace drives with a larger model but the pool won’t grow unless you replace all drives in the VDEV with larger models, one by one and allowing the resilver
