Topic: a question about backup and restore

[Denbert]

Hi,

I think I have a bad HDD (hdb) in my Raid Array, and therefore I would like to make a backup, remove the disk and for a short wile running the server in one disk, choosing reinstall option on single disk.

This is a home server and I’ve never been running Raid1 before, so I’ll think I could live with the risk of having a single disk server, while the HDD vendor accepts my RMA.

The question now is, will I work, or will the restore also restore system settings and therefore also the Raid Array?

Just to follow up!

I shut down the server and removed the HDD and started the server again.

Runs great and now the server are waiting for a new HDD.

Of course this is better than the solution a described earlier, I just didn’t thought that the server would accept the missing HDD at /dev/hdb
