Nevertheless, zpool status shows 0 read or write or checksum errors for this device. Is this normal? Does this hateful that the drive did work later a few retries on these events? Volition ZFS only react if the drive goes completely offline?

Please suggest,

Thank you in advance

My recollection is that it volition retry at the lower levels either ii or three times, so if it succeeds, it won't be reported to the higher levels (zpool.)

That'southward understandable, but at that place's a few of these: "(da36:mpr1:0:eight:0): Error 5, Unretryable error" which should take gotten up the chain to ZFS no?

Yes, it goes upwardly to ZFS. But ZFS may and then only try the IO using another disk (if the pool is redundant), or retry the IO on the same disk, every bit Eric said, and if that succeeds, it volition say that there is no problem. That's considering there is no problem with the pool itself. Remember, ZFS is a file system, with built-in RAID, but it does not incorporate built-in disk health management. In that location are other file/RAID systems that take congenital-in deejay diagnostics and health management, and even orchestrate disk replacement for you, but ZFS doesn't,

Clearly, your disk is ill, and you should do some work with smart to find out how bad it is, and perhaps consider retiring and replacing it.
