Hi, I decided to run another server to replicate data and save from one-machnine-failure. I remember ISP recommended GlusterFS but I can't read anything about it since debian jessie. That's why I have few question: 1. What is the best (recommended) solution for server replication supported by ISP3? 2. What solution can replicate also MySQL, PostgreSQL (not by files) 3. Since GLusterFS is master-slave structure, my question is if there's solution like Master-Master type? 4. Maby DFS-like FS would be better? Thanks in advance
We do not use GulsterFS anymore in mirror setups as it performs really bad with small files. See here for the current recommended setup: https://www.howtoforge.com/tutorial...abase-cluster-on-debian-8.4-with-ispconfig-3/
Thanks. I have a lots small files. Can You tell me the solution You use? I was thinking about ZFS + MoosFS or .. I don't know... looking for tested solution to implement on my servers with IspConfig.
As you can see in the tutorial, it uses unison to sync files. Basically, you can use any network file system or any other '2 way sync' solution for files.
I put www (Joomla) portals ... think its many small files... around 36000. I also test Gallera for MAriaDB/MySQL .. works fine but problem is when both machines are restarted at once... have to clear cache and strat mysql manually...
DRBD is not glusterfs and it's (most of the time) working very well. We had some problems with DRBD 8.3 in a splitbrain-situation that leads not non-usable volumes on both servers so we replaced this. Maybe it's working nowadays.
Hi. I'm using 8.9 with OCFS2 that (it theory) protects ic case of split-brain. What system You use instead of DRBD?
We are using simpe SAN-storages. Maybe 8.9 works better with a split-brain. You can easily test this.
