redo log: storage permission pre-check is need
What did you do?
-
When create changefeed with redo log storage config like this: [consistent] level = "eventual" max-log-size = 1 storage = "nfs:///mnt/nfs/var/nfs"
-
But some cdc server have not this directory "/mnt/nfs/var/nfs", the behavior right now is : create changefeed can be successful, but later storage persimission deny: "[CDC:ErrRedoFileOp]redo file operation: open /mnt/nfs/var/nfs/172.16.6.46:8420_mysql-test1_meta.meta.mtmp: permission denied"
-
It's better if storage directory/permission is pre-checked before successfully creating changefeed.
