Comments - Problem with the Galera wsrep_sst_method xtrabackup-v2

This could be due to some issue on the donor node. Check out the donor log for any error. You can even share it here, if you do not see anything obvious.

Thanks for helping. The full output from the doner is further below. I saw this message:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

I tested to be sure that I could connect as root on the local server on the doner node:

/opt/app/mysql/product/mariadb-10.1.11-linux-x86_64/bin/mysql -u root -pNotTheRealPassword --socket //opt/app/mysql/mysql.sock

I put the value for the password (NotTheRealPassword) in the .my.cnf file on the second node, cleaned out the directories on the second node and tried again. I got the exact same error: Here are all the lines from the doner log from the time I try to start the second node until it fails:

Do you also have "password" under the client section in your donor's my.cnf? If so, that could be the problem.

This issue was fixed in MariaDB 10.1.12.

I upgraded the donor node to 10.1.12 and tested xtrabackup 2.4.1 with a full backup to disk. I did a clean install of 10.1.12 on the second node and tried to start it. I'm still getting errors. I'll paste the logs below. I then decided to try switching from wsrep_sst_method=xtrabackup-v2 to wsrep_sst_method=rsync. This worked OK and synched the second node up with the donor node. For now, I'm planning to add the third node and do some benchmarking. I plan to come back to testing with wsrep_sst_method=xtrabackup-v2. Below are the mysqld logs from the failed attempt to sync with xtrabackup:

If you still didn't find the solution I suggest reporting as a bug - they can see if it's repeatable at least, and if not perhaps find help find out why it's failing in your case.

Just want to let you know that we did solve the problem. I will be repeating the tests that I performed with rsync using xtrabackup now. To fix the xtrabackup problem, we had two issues:

  1. . socat install problem. We went back a level to 1.7.2.4 and it installed OK.
  2. . We have MariaDB and xtrabackup installed in non-default locations. We had to setup environmental variables in wsrep_sst_xtrabackup-v2. We added a couple lines
    1. $(dirname $0)/wsrep_sst_common << after this line we added 2 lines below:
## Execute environmental variables for MySQL
. ${HOME}/.local 

Here are the contents of our .local file:

$ cat .local
export LD_LIBRARY_PATH=${HOME}/local/lib/
export LD_LIBRARY_PATH=:${HOME}/local/lib/

OK, as information, I've been doing performance testing with the Galera cluster that I created using rsync instead of xtrabackup. I do want to get back to the xtrabackup. I noticed that the socat utility that is required for xtrabackup was not correctly installed. I'm not sure if this might be my problem. In order to test xtrabackup, I have to tear down all nodes except primary and rebuild with xtrabackup. Since I'm in the middle of my performance testing, I'll have to wait before I can get back to the xtrabackup testing. When I get back to the xtrabackup testing and if I cannot fix the xtrabackup problem by fixing the socat install, then I'll submit a bug as you suggest.
