support Will HexOS reformat my drives if I re-add the server?

[viper1200]

So i had some issue recently and decided to just disconnect my server from Hex and re-add it.  When reconnecting i have this page, and while I'm pretty sure that it won't wipe my drives, i just wanted to get firm confirmation that the existing pool that the drives are in will not be erased and that the drives will remain as they are.  Really don't want to risk an accidental wipe.  The way that the checkbox warning and other things on the page are worded it feels as though it's going to wipe them when i connect.  This is likely not the case, but I am very paranoid about losing all the stuff I currently have.

Thanks for your help

I reinstalled after upgrading my LAN card, and all data was lost, I knew it probably would happen and it did, no great pain, as I was able to copy it again, only about 1.5 TB of Data, but I can see for larger amounts that would be a bigger issue.  I'm not sure if you can currently reinstall and keep data as it was.

Most users have reported not losing data but it is at your own risk. 

The less risky alternative is unplugging all your storage drives then going through hexos deck setup, once you are done with that you can turn off and then put everything back in

question did you have a raid z1 pool or a mirror pool? I'm just trying to figure out why hitting delete works for some users and not for others

Could this be linked to reinstall vs reclaim?

Those cases which I noticed which wiped the drives were all reinstalls of Hexos as in this case.

Other cases w/o data loss were reclaims of an existing installation.

I didn't look into every single case, but this was a pattern I noticed.

I noticed also this pattern.

Good observation, i'll see if i can look into that hypothesis
