Doc Text:
.The ceph tell command now displays proper error messages for the wrong mds type Previously, the ceph tell command did not display a proper error message if the mds type was incorrect. As a result, the command failed with no error message, and it was difficult to understand what was wrong with the command. With this fix, the ceph tell command returns an appropriate error message, stating "unknown <type_name>" when an incorrect MDS type is used.

Description Amarnath 2023-01-24 17:28:40 UTC 
Description of problem:
Error message is not descriptive for ceph tell command
ceph tell command with only <mds_name> giving below error

[root@magna028 ~]# ceph tell cephfs_1.magna023.yvyxvl client ls
error handling command target: local variable 'poolid' referenced before assignment

the error message `local variable 'poolid' referenced before assignment` looks not  descriptive. looks like there was a miss in some code path. 

same command with mds.<mds_name> is working fine
[root@magna028 ~]# ceph tell mds.cephfs_1.magna023.yvyxvl client ls | grep "id"
