Thanks for sharing this. I'll respond briefly, as much of what you bring up isn't really on topic for Open-iSCSI. But if you want to copy me on any other discussions, point me at Red Hat bugzillas, etc. please go ahead. <skipping network manager issue> > Second problem is the same as stated above, at shutdown, system would tear > down network interfaces and try to stop iSCSI before unmounting the iSCSI > volumes - this lead to data loss and fun times with MariaDB. I'm sorry you had to deal with that, it's been a difficult issue to get right. > Third problem is startup, RHEL7 MariaDB does not wait for remote volumes to > mount before trying to start: ... > Jan 16 17:26:08 mysqldb-01 mariadb-prepare-db-dir[6132]: mkdir: cannot > create directory ‘/mnt/db_data_01/mysql/’: Permission Denies .. > I've added: > "After=remote-fs.target" to mariadb.service as a workaround, but yah.. >From what I see the issue here is that you've configured mariadb to use a not-default datadir on an iSCSI disk, but systemd has no idea that the path /mnt/db_data_01/mysql is needed before starting the database server. Rather than add a general remote-fs ordering, it's probably better to have a Requires/After on the mount point (or create a path unit, but I'm not fully up on their use). Should changing a service configuration also require making modifications to the init configuration? Ideally not, but as this case shows it can. - Chris -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
