Good Evening,

I'm trying to migrate LXC containers from one cluster ( host running this script) to a stand alone proxmox server.
Keep getting error "401 No ticket"
Can someone help me on this ?
Bash: 
#!/bin/bash

SRV_02_ENDPOINT="apitoken=${SRV_02_TOKEN},host=${SRV_02_HOST},fingerprint=${SRV_02_FINGERPRINT}"

401 No ticket
 
the token part is wrong.. it should look like this apitoken=PVEAPIToken=${TOKENID}=${TOKEN_SECRET}, where ${TOKENID} seems to be 'root@pam!root-srv-02' and ${TOKEN_SECRET} 'fc2b2fa6-887a-4e46-b862-c0d6a754bd3a', but I'd strongly advise you to delete that one and create a new one since you posted it here publicly!
 
Thanks for your answer !

Token ahs been deleted just after having created the post ;-) ( and the system is not visible on the Internet)
Didn't want to mess up with the value as I was "convinced" my issue was a syntax problem.

For what it's worth, a "full example" would be useful in the docs !

Many thanks,
Etienne
 
Thanks, Token syntax is ok..

Now next question:

After successful run without the --delete 1 , I have two copies of my LXC: one "usable" on the destination node, and one in "locked" mode ( in migration with small plane icon).
I can't delete the source LXC ( computer says no: CT is locked (migrate) (500) )
What's the secret sauce to remove those "ghosts" ?

Looks like pct unlock does the trick...
 
Ticket syntax solved,

Using the same script, several LXC can't be migrated...
ths with big additional raw disks ( eg 100G like this one)

For other execution, just changing the VMID in the script and it works !
What could it be ?

the "fuse" feature is a problem here (and in general, everything that is root@pam only is, since the migration only works via a token that is by definition less-privileged). there is a "SuperUser" patch series waiting to be picked up again that would allow delegating the "power" of root@pam to arbitrary users/tokens, but it's not yet finished:

Thanks for the explanation !

If I understand correctly, I need to use backup/restore to migrate LXC with mutiple disks ... while remote-migrate is in "preview"...
 
no.. multiple mountpoints work fine, just nothing that requires root@pam (or some other things which are not implemented yet - like snapshots ;))

token has been created for root@pam ( root@pam is the only existing user on both source and destination pve).
I made sure the token is not restricted ( don't have the system at hands)
But I'll try to deactivate "fuse" and keep trying !
 
yeah, but even a non-priv-separated token of the user 'root@pam' is not equivalent to the user 'root@pam' for all the special "root required" checks ;)
