SOLVED ZFS errors

[mervincm]

I am in a bit of a situation and I am not quite sure how to proceed.

I have a 6-disk Z1 and last week I noticed some disk errors on a single drive. There were about 10 errors. I thought no problem, I have a spare disk on the shelf, so I can just replace it, I noticed that my backup (I have an old Synology NAS that pulls files via rsync for backups) was still running (I made slight changes to terabytes worth of files) so this was going to be days. There were zero errors on the data vdev overall so I had confidence that it was worth letting the backup complete. after a couple of days, I came back and there were now hundreds of errors on all of the other disks (the same number of errors on each disk) still no errors on the vdev, and data seemed to be still accessible. Thinking this looked more like a controller failure (than 5 disks happened to all fail simultaneously with equal bad sector counts) I took a look and found a fan failure. knowing it would kill my backup and I would have to do that again from scratch, I still decided to power down, fixed the fan, and move all 6 HDD to my LSI controller. After powering up it did a re-silvering, and when it was done I had 2 errors on each of the 5, and hundreds on the single drive that originally had the failure. And again still 0 errors on the vdev. Wondering if I was at the end of it I did a manual scrub/resilver again, this time it incremented to 4 errors per disk on the 5 and still 0 errors on the data vdev.

I have all the data backed up on my Synology via active backup for business. even if I can't complete this backup, I can tolerate the loss of the most recent changes. Also I have never tried a restore of this magnitude (40TB).
I have two spare disks of the same size (14TB) as the 6 in my data vdev.
I have all of my most critical data also replicated to the cloud (one drive)

Any thoughts on how I can get from where I am to a stable setup would be appreciated.

A few items would help provide better advice:
A complete description of your system and how it was set up. (I infer that the Z1 pool was initially on the "JM585 5 port M2 SATA", which is possibly NOT a proper, supported, HBA). Also, 12 TB for the spares does not match with 14 TB in your signature.
The output of zpool status, within CODE tags (not ICODE, please).
SMART reports from the drives, also within CODE tags.

But at this point, I'd say you need to buy at least five more HDDs to make a new raidz2 vdev with at least the same capacity as the failing pool (so 5+2 for a 7-wide Z2 with the same capcity as the 6-wide Z1) and move your data to it. Raidz1 is not considered safe enough with large HDDs ("RAID5 is dead" story…).

I fixed the error, it is indeed 14TB disks, thanks.
Yes the 6x 14TB disks were previously on the JM585. I originally planned to have 6 more SATA SSD in here, and had that connected to the LSI.

  pool: boot-pool
 state: ONLINE
status: Some supported and requested features are not enabled on the pool.
        The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
        the pool may no longer be accessible by software that does not support
        the features. See zpool-features(7) for details.

I finished my outstanding backup and am performing a second copy to USB-HDD just in case.
I noticed that my previous reboot aborted one of the long smart drives, so I have restarted that one as well.

Despite all this activity, I have not seen any additional errors incrementing, but I still think it makes sense to at least rebuild this pool.
As long as the remaining Long SMART test completes w/o failure .. Is there anything in these disk smart tests that make them unsuitable? I don't think so...

I am thinking

- backup/document all my folder structure/permissions / data sets etc. hints here would be appreciated
- offline all apps
- delete the datasets then pool, quick wipe disks
- apply outstanding Seagate HDD firmware (SN04) update to 6 disks hope to be able to do within truenas scale, but I can physically move them to another system if need be.
- rebuild as 6disk Z1 (understand Z1 is not best practice, but I can take the availability hit and would rather allocate the extra disk to offline backups)
- create a special vdev for metadata on a mirror set of 280GB optane disks, set special_small_blocks=64K
- recreate pool and data sets
- restore my 40TB data from the Synology backup, testing my restore ability
- restore file permissions
- review pool health and errors.
- online all apps

Just an update. So far no hardware appears damaged / unusable. All disks completed a long SMART test and rebuilt / re-silver without a single error. All firmware updates were done w/o incident, All data was restored from backups without issue. I lost old snapshots, so I only have the most current versions but that's a small price to pay. I applied permissions via scripts, so that was easy to reapply. I suspect the fan issue just lead to an overheating low-end controller, and now everything is on the system board or LSI.

a (hopefully final) update. So far so good, no incrementing errors in SMART, and no errors detected by ZFS. I installed Scrutiny to keep an eye on my drives, and despite it warning me about the command time-out errors that accumulated before, they are not incrementing. Not ideal, but given my now-tested backup, I am going to run with it. all three drives with this>zero were on a single power cable, that I have now reseated and contacts cleaned with quality contact cleaner.
