MySQL data directory move

MySQL & MariaDB Percona XtraDB Cluster 5.x
10

@bbalderman28 I ran into issues moving the datadir, specifically:

2023-04-09T18:24:02.097836Z 1 [ERROR] [MY-011011] [Server] Failed to find valid data directory.
2023-04-09T18:24:02.098040Z 0 [ERROR] [MY-010020] [Server] Data Dictionary initialization failed.
2023-04-09T18:24:02.098105Z 0 [ERROR] [MY-010119] [Server] Aborting

I set the datadir to its new value in the conf file, as well as making sure the mysql user has permissions on the new directory. To be sure I disabled AppArmor to test, and still giving this error.

Wondering if you would be willing to share what you did differently in the second attempt that made it work?

Thanks!
