I used to use mysql data in /var/lib/mysql, now I have created new partition and created tank on it to use with zfs.
After that I follow this steps to move my existing mysql data to new dir: https://serverfault.com/a/539729/184573
Everything worked ok so I have imported new big db (100 GB) and now is not working anymore.
I’m on /tank/mysql, using zfs and everything is working ok
imported new db, mysql was working ok
stopped mysql service and executed zfs
snapshot tank/[email protected] now I cannot start mysql because of
- tried to chown mysql:mysql /tank/mysql -R , still same error
I have google that problem and none of solutions helped me. Permissions, settings,… everything seems to be ok.
OS: Ubuntu server 14.04.
Server: IBM X3200 m3
What could be a problem?
Why don’t you just put the ZFS dataset in the location MySQL expects?
zfs set mountpoint=/var/lib/mysql tank/mysql
Now you don’t have to worry about strange permissions on
/tank and everything looks normal to the rest of the system.
