How do I create a mount point on the RAID1 that is persistent or always there, then prove it?

Repurposing an old server to be a backup repository. Name of box is backup. Ubuntu ver 20.04, command line only. How do I make sure the files I copy to it from other servers using XCOPY or SCOPY are actually going to the RAID1? How do I create a mount point on the RAID1 that is persistent or always there? Or do I already have a mount point and do not know it? How can I make it happen and prove it is working?

A mountpoint needs to be created on every server that is going to access your RAID. It is not created on the RAID. A mountpoint is a directory, so you need to create a directory with the same name on every server and add a corresponding line to `/etc/fstab` on every server. Tip: use `lsblk `f` instead of `sudo blkid` to get more useful output.

Thank you. I have one server. I am attempting to use it as a backup repository. All other devices are windows servers. When I save files to it, I think they are not going to the RAID but on to the boot drive. How do I make sure I can get the flies to save to the md0p1 partition.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
