rsync using -a parameter may cause error

[xiaosiyu0603]

The target folder to deploy on server is on NFS, so --omit-dir-times argument is needed (reference); the owner of target folder is not me, which means I'm not allowed to change its owner, so --owner/-o argument can not be used, while -a includes -rlptgoD and causing error. Files can be synchronized correctly.
