Swap out defective HDD

[Dellyjoe]

Hello everyone,

I'm in the process of trying to replace a failing hard drive and I'm currently following https://www.truenas.com/docs/hub/tasks/advanced/disk-replace/

After Scrubing the pool and putting the defected hhd to offline I get this error

[EFAULT] Command swapoff /dev/mirror/swap0.eli failed (code 1): swapoff: /dev/mirror/swap0.eli: Cannot allocate memory

Code:

Error: Traceback (most recent call last):

Does anyone know what the issue is?

Thank you for reading,

That sounds like a bug... Can you please make a ticket on jira.ixsystems.com so we can investigate? We'll be able to troubleshoot with you there and perhaps find a work-around.

Yes no problem, I use Jira at work so I should be able to figure this out.


NAS-108270 Is the ticket number

Thank you again,

Issue resolved

It was my sever running out of memory

I´m getting the same error message "Command swapoff /dev/mirror/swap0.eli failed (code 1): swapoff: /dev/mirror/swap0.eli: Cannot allocate memory" when unmounting a ZFS formatted USB-Disk. This seems to be reproducable.
The only way for a clean unmount seems to be rebooting :-(

Any hints?
