Backup NG Remote "File already exists"

[goorooj]

Hello Forum,

community edition, test system.
i was rearranging my Nas, so i disconnected the Remote i used for Backups, made a Raid10 instead of Raid5 ( speed ) and recreated the shares.
the backups were not important, was just a test.
now when i tried to reconnect the remote ( same share name, same server ) it said

remote.test
{
 "id": "bb4532ab-12a7-4103-9420-7847da8ca9ff"
}
{
 "errno": -17,
 "code": "EEXIST",
 "syscall": "mkdir",
 "path": "/run/xo-server/mounts/bb4532ab-12a7-4103-9420-7847da8ca9ff",
 "message": "EEXIST: file already exists, mkdir '/run/xo-server/mounts/bb4532ab-12a7-4103-9420-7847da8ca9ff'",
 "name": "Error",
 "stack": "Error: EEXIST: file already exists, mkdir '/run/xo-server/mounts/bb4532ab-12a7-4103-9420-7847da8ca9ff'"
} 

i destroyed the remote now and made it new, only to see

remote.test
{
  "id": "86109d77-9600-48c6-b131-0ca475cd1ad4"
}
{
  "code": 1,
  "stdout": "",
  "stderr": "mount: only root can use \"--options\" option

  "failed": true,
  "signal": null,

mount: only root can use \"--options\" option

is this expected behaviour, does the xo vm need a reboot between this operations?

ok, logged into linux, su root, and tried the command on the console

 mount -t nfs 192.168.30.60:/mnt/Brutus/Remote /run/xo-server/mounts/86109d77-9600-48c6-b131-0ca475cd1ad4 -o vers=3
mount.nfs: requested NFS version or transport protocol is not supported  

tried without -o vers=3 and it worked.
