Hello all. I’m running Truenas Core with multiple pools. One of them is 8x4tb WD RED, all connected on a PCI to Sata board. Pool status is ONLINE (Unhealthy), I already changed all SATA cables and checked all connections. Six disks are EFRX CMR, two of them are EFAX SMR these two SMR didn’t pas…

okay, sounds stupid but… I found the issue. I run zpool status -v and found an error on one file in the pool. Tried to copy it on my Mac and in fact it was unreadable. deleted, restarted the server and now the pool is ok. I think Truenas should be more “verbose” on these things, instead of searc…

A pool comprised of a vdev with 8 drives… and it still could not repair a single corrupted file?

IDK, I ran many scrubs but the error never gone away. I tried ZPOOL STATUS today (shame on me for not trying it before) and found the issue. Sounds strange, but now it has been solved and this post can be useful for the future.

The concern is that one of the main reasons for using ZFS is to protect against this exact type of thing. What if that was an irreplaceable file with sentimental value? (Leaving out the topic of backups for the time being.)

Could be a stripe. OP doesn’t say.

I know, this time the file was just a mkv movie, but next time could be something important. My concern is that I cannot investigate on what caused the corruption and there wasn’t any notification or message on what caused the pool to show as “unhealthy”. after deleting the file, performed a long …

[image] rdcustom: SMR [image] rdcustom: I think Truenas should be more “verbose” on these things …Ouch. The reason Truenas isn’t more “verbose” is because quite a few things have to go wrong on ZFS for this to happen. Now it is a guessing game of is it the SMR drives, the pool configur…

Let’s clear something here: this is an home server, so I don’t need fancy hardware. PCI board is an ASM1064. OP didn’t posted the error cause didn’t took a screenshot, I don’t think I should be placed on a cross like Jesus, right? Maybe the controller caused the corruption, IDK As told before, I…
