[Users] OVZ 7 beta - ploop backup fully functional?

[jjs - mainphrame]

Greetings,

I've been running some test containers on OVZ7 beta, and, while I realize
not all functionality is in place yet, they have been so dependable that
I'm starting to depend on them.

So, understandably, I was looking at backups, and my first tries with vzctl
snapshot failed. I don't want to spend a lot of time troubleshooting
something that's not yet known to be working, but in case it is, has anyone
else had better luck?


Here is the result of my attempt to make a backup:

[root at hachi vz]# vzctl snapshot 1001
Creating snapshot {57c8aa0d-1c04-4469-9d1e-c95fab04bd01}
Storing /local/vz/private/1001/Snapshots.xml.tmp
Setting up checkpoint...
Failed to checkpoint the Container
All dump files and logs were saved to
/local/vz/private/1001/dump/{57c8aa0d-1c04-4469-9d1e-c95fab04bd01}.fail
Checkpointing failed
Failed to create snapshot
[root at hachi vz]#


The last few lines of the dump log contain these clues:

(00.570576) Error (proc_parse.c:404): Can't handle non-regular mapping on
8366's map 7f2164d63000
(00.570582) Error (cr-dump.c:1487): Collect mappings (pid: 8366) failed
with -1
(00.570746) Unlock network
(00.570751) Running network-unlock scripts


There is no pid 8366 in the CT but on the host that pid corresponds to the
mysql instance running in the container that I'm trying to snapshot:

[root at hachi vz]# ps -ef|grep 8366
27          8366    7098  0 14:03 ?        00:00:00 /usr/libexec/mysqld
--basedir=/usr --datadir=/var/lib/mysql
--plugin-dir=/usr/lib64/mysql/plugin
--log-error=/var/log/mariadb/mariadb.log
--pid-file=/var/run/mariadb/mariadb.pid --socket=/var/lib/mysql/mysql.sock

So, is this something that ought to work?

Regards,

Joseph
