Add disk to Proxmox Backup Server

[tylko]

Hi, I'm new to PBS. I have installed PBS to separate physical machine, connected to it an iscsi disk (making lvm, adding to a new vg, created fs and mounted). I can see mounted disks

root@pbs:~# df

/dev/mapper/iscsi-netapp 4215933576   90140 4001615468   1% /iscsi

but the only one is ready to be used by PBC

How to make the second, iscsi disk, available to PBS

 

[Frank666]

sry i'm also new to PBS so i don't know if my question is bullshit

have you already added a Datastore with the /iscsi Path?
I would think, that the proxmox-backup-manager command just shows the disks which are configured as a storage

 

[tylko]

No I have not because I believe that first I have to see iscsi volume as a disk in gui or by using proxmox-backup-manager command.

 

[dcsapak]

if you manually mount your filesystem, you do not need to go via our disk management. this is intentionally limited to local disks and simple setups
(since there are basically infinite ways to configure storage)

if you have your target storage mounted and setup, simply add a datastore in that directory (or a subdirectory)

 

[tylko]

Thanks for advice, it works. Now I'm less new than a few hours ago

Anyone new that sees this thread; you can use the follow steps to 1) Mount 2) Create a Datastore w/ the new drve:
1) Select 'Storage/Disks' under the Administration module
2) Select 'Directory' tab
a) Create: Directory
3) Select the new drive (Should auto-populate) give it a name/ID
4) Select the Filesystem
a) Add as Datastore should be checked by default
5) Select 'Create'

This will Format, Mount, and create the Disk as a Datastore for you via ProxMox BS GUI.

From there you just need to point your PVE/PVE Cluster to the PBS and wham bam you're good to setup a backup schedule.

Sorry not related to this thread; but do you find it worth the money to have a ProxMox Sub? I'm very curious what the Pros/Cons are from the Non-Subsrciption side are.

So I'm having a strange issue after following steps in #6 above. I removed a PBS datastore (named "backup") and now trying to recreate - I was testing creation of an encrypted destination for PVE backups.

I have removed the existing datastore:

systemctl disable mnt-datastore-backup.mount

proxmox-backup-manager datastore remove backup

rm /etc/systemd/system/mnt-datastore-backup.mount

umount /dev/sdd1

rm -rf /mnt/datastore/backup

systemctl restart proxmox-backup proxmox-backup-proxy

sgdisk --zap-all /dev/sdd

And confirmed in UI and:

root@pve:~# proxmox-backup-manager disk list

Now when I go into PBS and attempt to create a directory:







I attempted again without selecting option to create datastore:


Looking at logs:

Not sure what to do from here. I have trying restarting PBS host with no luck.

So I have resolved my issue. In case someone else comes across this....

sgdisk --zap-all /dev/sdd did NOT remove all GPT metadata. I had to run gdisk /dev/sdd, select x (Expert) and select z (Zap). I was then able to create directory and add Datastore via UI.
