Running MySQL 8.0.21, which is using InnoDB encrypted tables. The MySQL keyring file is mounted over NFS.
When running xtrabackup on it (as root, and piping through xbcloud to send to S3), I’m getting some errors with the keyfile (see below). MySQL finds the keyfile with no problems on startup. I’ve verified the mount is there. I’ve also tried copying the keyfile to the machine locally, and using the --keyring-file-data option, but I get the same results.
Not sure if the the MY-011370 is normal, and I’ve actually hit a bug, or what.
Any thoughts? Thanks in advance!
