[PROXMOX] Migration problems between 2 nodes

Networking Networking Software

Good evening,

I’m trying to migrate a vm between 2 nodes.
I removed all backups and snapshot of the vm from the system.
The vm is 60G in size. When i do the migration i get the following error

I do have to note my second node “virtual” runs from a usb stick with a size of 32G.
But for storage i set up a ssd size 230G

How can i get my vm to the “virtual” node.
I tried to set the first node storage to shared, and it will migrate the container. But i need to move everything.
I want to take the first node out of service.

I test with a vm with 32G container and i move to the ssd without any problems.
So i don’t think my usb install is the issue…i hope it is.
Anyway i hope some one can help me to move this AD server.

thanks in advance…

Do u have storage for both nodes mounted to the same location?

3

what do u mean?

The cluster looks like this;
pve2 is not exciting.
storage has the disk images for pve1 and is located on pve1 and is not shared
virtual_ssd has the disk images for virtual and is located on virtual is shared

cluster

error says its trying to put copy of the disk in the storage location. If there is not enough free space in storage … then migration fails. Hence error about writing disk there.

5

run df -h on both nodes

6

This is the output

df%20-h
df -h.PNG602x742 15.8 KB

you have /mnt/storage on first node. and /mnt/ssd on second node.

Fix that and migration should work.

8

But i don’t know what i should fix.
I’m a linux/proxmox noob.

I tried to look online for solutions, but google is no help for me :cry:

need to reconfigure your host storage so both disks are mounted on each host at the same location… other VMs will have to shutdown/moved manually most likely.

10

U mean storage on pve1 has to be shared with virtual?

shared
shared.PNG1139x285 14.4 KB

11

actually a hack solution might be this:
on virtual host node.

ln -s /mnt/ssd /mnt/storage

12

no.
each host has local storage only. That will just throw a different error when it tries to use the storage as if it was shared.

unless the actual storage is shared b/t both nodes… dont mark it as shared.

14

I marked all drives to be not shared and did ln -s /mnt/ssd /mnt/storage on the vitrual node

15

run on virtual node

ls -la /mnt/

16

okey what where looking at/for?
ls

17

dont think it worked… storage should be a link pointing to /mnt/ssd

18

the folder ssd, storage and vserver already excised in /mnt. that did not change

19

i re-did ln -s /mnt/ssd/mnt/storage
and got this response:
ls

20

is this what you expected?
ls2

21

no… remove that

should have been /mnt/ssd

not /mnt/ssd/mnt/storage

that is also not in the /mnt folder
