Galera cluster maintenance
最小£36GBP /小时
We're looking for a Galera cluster administrator to perform maintenance in our production environment (three MariaDB nodes on Debian). The right candidate has excellent knowledge of Galera clusters, MariaDB, and server admin for supporting the daemons, and good communication skills.
Services must remain operational 07:45-02:15 GMT and data loss isn't acceptable - we have a range of backup tools to assist. We'll ask you to sign a non-disclosure agreement.
We currently have 93% disk space used and can't delete data because the log file fills the disk and is not being consumed by replicas. We'd like to fix this over the weekend, and identify further issues for the next round of maintenance.
If we complete this job successfully then we'd like to invite you to join our team for a short time to maintain availability of the cluster and migrate to a managed solution shortly.
Please help us choose the right candidate by answering these questions;
1. Give an example cause of a cluster losing quorum?
2. A server has no disk space left. What procedure would you use to fix this?
3. How much DBA experience do you have?
4. Downtime is only acceptable 02:15-07:45 GMT (4.5 hour window). What is your local timezone, and are you comfortable with this?
Thank you for taking the time to read and apply thoroughly, all applications will be read carefully.
