Use docker run a namesrv container There are log files when data volumes are not used, but There are no log files when using data volumes

// example1 log files docker run -d --name huigenamesrv -p 9876:9876 apache/rocketmq:4.9.2 sh mqnamesrv

//example2 no log files docker run -d --name huigenamesrv -p 9876:9876 -v namesrv:/home/rocketmq/logs apache/rocketmq:4.9.2 sh mqnamesrv

Use docker run a broker container There are log files when data volumes are not used, but There are no log files when using data volumes

// example1 log files docker run -d --name huigebroker -p 10911:10911 -p 10909:10909 -p 10912:10912 -e "NAMESRV_ADDR=192.168.154.128:9876" apache/rocketmq:4.9.2 sh mqbroker

//example2 no log files docker run -d --name huigebroker -p 10911:10911 -p 10909:10909 -p 10912:10912 -e "NAMESRV_ADDR=192.168.154.128:9876" -v brokerlog:/home/rocketmq/logs apache/rocketmq:4.9.2 sh mqbroker -c ../conf/broker.conf

Use docker run a broker container When the store is not mounted, it starts normally; when the store is mounted, an error will be reported, and there is no store data in the data volume.

// example1: no mount store ==> success docker run -d --name huigebroker -p 10911:10911 -p 10909:10909 -p 10912:10912 -e "NAMESRV_ADDR=192.168.154.128:9876" -v brokerlog:/home/rocketmq/logs -v brokerconfig:/home/rocketmq/rocketmq-4.9.2/conf apache/rocketmq:4.9.2 sh mqbroker -c ../conf/broker.conf

// example2 : mount store => error container exit
docker run -d --name huigebroker -p 10911:10911 -p 10909:10909 -p 10912:10912 -e "NAMESRV_ADDR=192.168.154.128:9876" -v brokerlog:/home/rocketmq/logs -v brokerstore:/home/rocketmq/store -v brokerconfig:/home/rocketmq/rocketmq-4.9.2/conf apache/rocketmq:4.9.2 sh mqbroker -c ../conf/broker.conf

why??? how to do ??
