Can I temporarily disconnect one disk to free a SATA port?

[hako]

I have a hard drive from my computer that I want to import into my pool, since the network share is being weird and not copying things correctly.
I only have six SATA ports on my motherboard, and all of them are filled. (1: boot drive, 2-6: pool drives)
Is it okay if I offline and disconnect one single disk from my pool to quickly import the data from my drive, and then have the pool resilver afterwards?
The pool and drives are all very young, so I'm not concerned with any of them possibly failing when rebuilding.
Alternatively, could I remove the boot pool while TrueNAS is already running? I'm assuming that's a 'no', but you never know...

Here is my pool:

Code:

  pool: boot-pool

With a raidz1 you should be concerned about the lack of redundancy while importing data…
The best option is to fix network sharing so the NAS works as intended. Second best option would be to plug the drive with a USB adapter to import.

3rd option is to use a USB flash drive to mirror your SATA boot-pool device. Then disconnect the boot-pool SATA device, attach your import disk, perform the import, then reverse the process.

What about connecting the disk to a workstation and copy the data via SMB?
