I have 3 computers with a combined total of 10 6TB Hard Drives, all WDC WD60EZAZ-00SF3B0. All computers are Ubuntu 24.04 so software tools for other systems (Windows) will not work on my machines.
The other hard drives in the computers are not having issues.
For these 10 drives, the short tests run fine, but extended tests get stuck at 10%:
Self-test execution status: ( 241) Self-test routine in progress... 10% of test remaining.
The extended self test routine recommended polling time varies from drive to drive from ~200 minutes (~3.5 hours) to ~750 minutes (~12.5 hours).
I have had the tests run for about 3 days with no change in status, so I presume the tests are stuck. I have cancelled the extended tests and rerun them multiple times to no avail. I am fairly confident that the drives are healthy since they pass the short offline test and I would not expect all 10 drives to be failing at the same time.
I’m not sure if this is a problem with the manufacturer or my configuration.
It seems there might be a problem with WDC drives:

https://community.synology.com/enu/forum/1/post/131996/
Maybe some suggestion to change polling settings which I’m not sure how to do:
https://forums.unraid.net/topic/118392-smart-error-hdd-extended-self-test-stuck-at-10/
I believe the drives are active while the test is running and not powered down or in a standby/sleep state.
I have tried some of the suggestions here, but I don’t think they make any difference since the drives are in an active/idle state already:
https://superuser.com/questions/766943/smart-test-never-finishes-what-can-be-done-to-let-them-complete
When running the tests, I’m not running any heavy workloads on the drives.
All of these drives are in RAID arrays which I have posted below. Not sure if this should be a problem as I test each drive separately.
I have provided the configuration for the computers below, and I am happy to provide more information as is necessary.

Also, I do not see the extended test at the top of the SMART Self-test log structure revision number 1 which I should expect. I would like to fix this to be able to see the progress from there as the extended test is running. I believe I am able to see the short tests in the log structure as it is running, just not the extended ones.
