Flush logs hangs
We have a 3-node Galera cluster running with Mariadb "Server version: 10.1.22-MariaDB MariaDB Server" . running on Centos 7.
$ uname -a Linux xxxxxxxxxxxxxx 3.10.0-693.21.1.el7.x86_64 #1 SMP Wed Mar 7 19:03:37 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
When I issue a "flush logs" the statement hangs.
$ mysql -umysql_admin -p* -e 'show processlist' +---------+-------------+-----------------------+------+---------+---------+--------------------+------------------+----------+
| Id | User | Host | db | Command | Time | State | Info | Progress |
+---------+-------------+-----------------------+------+---------+---------+--------------------+------------------+----------+ ...
| 1593327 | mysql_admin | localhost | NULL | Query | 2748 | init | flush logs | 0.000 |
... +---------+-------------+-----------------------+------+---------+---------+--------------------+------------------+----------+
I can't find any reason why this happens. All filesystems have enough space.
Any ideas what can cause this?
