scylla-jmx.service: Failed at step CHDIR spawning /usr/lib/scylla/jmx/scylla-jmx: No such file or dir #235

formatting nvme drive to ext4, then setting workdir to that drive and removing old data and commitlog directories, then running scylla_setup causes jmx server to crash

systemd[8722]: scylla-jmx.service: Changing to the requested working directory failed: No such file or directory systemd[8722]: scylla-jmx.service: Failed at step CHDIR spawning /usr/lib/scylla/jmx/scylla-jmx: No such file or dir systemd[1]: scylla-jmx.service: Main process exited, code=exited, status=200/CHDIR scylla-jmx.service: Failed with result 'exit-code'.

for some reason /usr/lib/systemd/system/scylla-jmx.service isnt regenerated and WorkingDirectory is left at old path. setting new path doesn't help and sends back the same error.

only workaround so far is leaving empty path like in this 3 year old commit

https://github.com/scylladb/scylla-jmx/commit/6311525346c8d3b878ea78768b294fa5ba6c4854

hopefully this saves people formatting and mounting new drives some time

It's unclear to me if scylla was properly reinstalled. A log of the installation would be helpful.

scylla has been running for 350 hrs uptime no issues before, same installation as i have did in past. cql, rpc, api, evreything worked. when replacing a broken nvme mounted as / with a new nvme mounted at /mnt/db-example/scylla the config was also edited to change all directory paths and working dir path to the new mounted nvme. scylla server starts properly, connects to all nodes as expected. only issue is nodetool that is unable to connect to api at port 10000 with the chdir error. leaving a blank entry for workjing dir in /usr/lib/systemd/system/scylla-jmx.service and reloading daemon the restrating scylla-jmx.service solves issue for some reason
