Drives keep resilvering

[Xander May]

But this however:

Code:

SMART Self-test log structure revision number 1
Num Test_Description Status Remaining LifeTime(hours) LBA _of_first_error
# 1 Extended captive Interrupted (host reset) 90% 139 -
# 2 Short captive Interrupted (host reset) 70% 139 -
# 3 Extended offline Aborted by host 90% 139 -

...The SMART tests don't finish properly. It is a definite worry to me. If it is user-induced - retry. If not.... something is fishy.

I aborted the very first long test, after that I left it for 4 hours.

Yes, but that's consistent with some other flaky piece of hardware causing the drive to disconnect and reset intermittently, which could also lead to the ZFS checksum errors.

EDIT: for clarity - it could well be the drive itself, but didn't you see trouble on more than one drive?

I saw trouble on two drives. the third seems fine but I havent run any SMART tests on it. Other drives that were fine for months are also now misbehaving. So probably MOBO...

Extended self-test routine recommended polling time: ( 235) minutes.

Might be you still didn't wait long enough. When a self-test is running you can check its progress using smartctl.

Before using a system you should spend at least a month testing it and learning how to use freenas. This means burn in the CPU, memory and HDDs. Then learn how to replace a drive.

199 UDMA_CRC_Error_Count is very high...
This usually means a bad connection to the drive.
Might mean bad cable. Worth changing cables and see how it goes.
