NBD setup - No such item
-
Does it ring a bell @florent ?
-
@Tristis-Oris said in NBD setup - No such item:
i'm try to configure NBD backups. Enabled NBD at pool link, enabled at XO, everything looks fine, but at tasks i see that:
Not sure is it a problem.I am not sure to understand the problem, is it the XO user authenticaton task ?
For NBD, if it is enabled you should have a message in the backup log :
-
@florent task
reconfigure ip pf: eth4 - no such item
. Both of them i configured for NBD.
I have no such message at backup log, so it not working. -
@Tristis-Oris does the XO have access to the NBD enabled network ?
-
@florent I don't get that moment.
Both interfaces at same vlan. But on host it a dedicated link, on VM it's virtual link at trunk port.Now i switch XO VM network to host NBD link - this tasks not dissapeared.
Test backup done as usual one, with a bit less speed than before: 60MiB vs 80-90.also probably found a visual bug. After XO update
preferNbd = true
atconfig.toml
removed, but at already configured backup job this settings still availabe.
-
@florent i removed all frozen tasks, again enabled nbd, etc. But anyway can't make it work.
Sure i read all guides at blog, all steps looks correct. Any hints? -
@Tristis-Oris That is strange
We are finalizing the release today, I will take a deep look tomorrow if it's ok for you -
@florent sure, no rush here.
-
I tryed multiple time to have te "reconfigure ip of .." task, but didn't succeed.
What I did :
- on the pool > network : activated NBD connection
- on the delta backup job : enable NBD
I didn't have to change anything else
-
@florent i don't get
reconfigure ip
second time, but backups still without nbd. -
@Tristis-Oris ok
What are the network accessible by the XO VM ? does it contains the NBD enabled network ? -
@florent as i say, XO only one interface it's same host interface where NBD is enabled.
-
@Tristis-Oris And you don't have message like
can't connect to nbd server
in the system log / Xo-server output ? -
@florent never seen such errors. At which step it should happens?
-
@Tristis-Oris when launching a backup, between the snapshot and the beginning of the the transfer. It should try to connect to the host(s) NBD server
-
@florent also , is there a firewall/network filtering between XO and the host ? the conneciton to the NBD server go through the port 10809
-
@florent is NBD server running at dom0?
for clear test: disabled nbd, removed all XO logs. Enabled NBD on host, changed XO interface to this one, run backup task with NBD > no one error at logs.
-
@Tristis-Oris yes the NBD server run in the dom0, one per host
-
@florent hm. Telnet to 10809 is refused even from dom0, to both backup interface and management.
We have no any additional firewalls at network. Host's iptable looks fine.What a name of service, to check if it running?
-
also add
filter = 'xo:backups:DeltaBackupWriter'
to config.toml. Anyway no one error during backup.
