vzrestore disconnect halfway

[pats]

Hi,

Recently i had issue with my Main server and i tried to Restore dump on a Backup server(after installing Debian 6 + Proxmox).

root@prox2:~# vzrestore vzdump-openvz-100-2012_07_08-12_00_07.tar.lzo 101

But putty (ssh client) disconnected halfway.
Since there's no progress-bar or something i don't know how long back it got disconnected..

i login to ssh again, saw there's no vzrestore process in memory.
root@prox2:~# vzlist
Container(s) not found

But i noticed increase in disk usage, so i thought of taking a look
root@prox2:/var/lib/vz# du -h --max-depth=1
8.0K ./lock
8.0K ./root
64G ./private
16K ./template
4.0K ./dump
4.0K ./images
64G .
root@prox2:/var/lib/vz#

so private had some contents while root looked empty

root@prox2:/var/lib/vz# ls -l private
total 4
drwxr-xr-x 21 root root 4096 Jul 22 14:21 101

So, can i 'rm -rf /var/lib/vz/private/101' and 'root/101' ?

Where other places i can look for files relating to half-baked 101 ?

Does vzrestore write any log file - where its located?

Also how can i check/test the file vzdump-openvz-100-2012_07_08-12_00_07.tar.lzo if the file is ok, no errors in it?

Thanks

yes

You should see a task on the task list.

Also how can i check/test the file vzdump-openvz-100-2012_07_08-12_00_07.tar.lzo if the file is ok, no errors in it?

maybe with 'tar tf filename'

yeah i found:
extracting archive '/root/vzdump-openvz-100-2012_07_08-12_00_07.tar.lzo'
tar: ./home/ospinter/mail/ospinter.co/lucy/.neomail-trash/cur/1157095052.000020.mbox:2,S: implausibly old time stamp 1969-12-31 18:00:00

Not sure if vzrestore exited due to 'implausibly old time stamp' or due to Session timed out on ssh.
Any ideas?

 

[dietmar]

or due to Session timed out on ssh.

You told you got a ssh session timeout, so it is likely that it has been killed by that.

 

[pats]

How do you guys tackle the ssh timeout? if the dump is big then definitely there will be session-timeout.

last time when i was rsync'ing some big backups from one server to another server they timed-out, and after that i always use 'rsync --progress' so now there is no timeout.

Anything like this in vzrestore? progress bar/percentage or verbose mode - some activity on-screen to keep-on the session?

thanks

I do not get such timeouts here (the session is not idle if you run vzrestore). But maybe that is a ssh client setting (ServerAliveInterval).

hmm... in Putty i see

Connection -> Sending of null packets to keep session active
Seconds between keepalives (0 to turn off)

i think i have to change keepalives from 0 and test ?
