Unhealthy Pool

Hello and new to Truenas so I am a rookie. Just setup Truenas and installed 2 red WD 6Gb drives and created a striped pool. I am using it to store media files for Plex. On one of the 6Gb drives I am getting Checksum errors. What are some of the things I should try? Could it be I have a bad drive or should I try and move it to a new sata port? If I move it will it destroy my pool?

Warning: settings changed through the CLI are not written to the configuration database and will be reset on reboot. root@truenas[~]# zpool status -xv pool: media state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-8A scan: scrub repaired 0B in 00:58:34 with 11 errors on Tue Apr 5 21:52:52 2022 config: NAME STATE READ WRITE CKSUM media ONLINE 0 0 0 gptid/5fa0a006-b45b-11ec-8827-7824af3aa446 ONLINE 0 0 3 gptid/5faa3f91-b45b-11ec-8827-7824af3aa446 ONLINE 0 0 10 errors: Permanent errors have been detected in the following files: /mnt/media/media/Kids/Despicable Me 2.avi media/media:<0x2b> /mnt/media/media/Movies/Star Wars/The Mandalorian/Star Wars - The Mandalorian Movie - Part I (2019).mkv /mnt/media/media/Kids/How to Train Your Dragon - The Hidden World 2019.mkv /mnt/media/media/Kids/onward.2020.catalan.multi.1080p.bluray.x264-despacito.mkv media/media:<0x86> /mnt/media/media/Kids/Goosebumps 2015.mkv /mnt/media/media/Movies/Star Wars/The Mandalorian/Star Wars - The Mandalorian Movie - Part II (2019).mkv /mnt/media/media/Movies/Free.Guy.2021.1080p.HDRip.X264.DD5.1-EVO.mkv

CHKSUM errors are usually (but not always) the result of a bad cable. Reseat (preferably replace) the SATA cable.

You do realise that with a stripe you have no resiliancy and no way of fixing bit rot / bad files. Lose one drive and you lose the whole pool.

You need to send these back and get CMR drives.


SMR drives are no good for ZFS and should not be used with TrueNAS.

Yes I realize that about the redundancy but I really don't need it. This pool will only be for video files for Plex. If I lose them I could replace the files. I would rather have the space than the redundancy.

You may have misunderstood what @NugentS said. If you lose a drive, you lose the *pool*, not just some files. Replacing terabytes of files is a terra-fying prospect in most cases.

Yeah after thinking about this I am sending the 2 x 6TB SMR's back and getting 2 x 8TB CMR's and will run them mirror. Thanks for all the suggestions. Like I said I am new to Truenas but I have to say this is a powerful platform and I am liking what I am seeing.
