ceph crushtool piping commands is not working

Question

I am running this command inside a ceph monitor container

ceph osd getcrushmap | crushtool -d - | less 

It shows me the output of the decompiled crush map. When I try with

ceph osd getcrushmap | crushtool -d - | crushtool -c - 

I get an error, input file - not found

Any ideas how can I make this work ?

Answer 1

try with 2 steps :

ceph osd getcrushmap -o {compiled-crushmap-filename} && crushtool -d {compiled-crushmap-filename} -o {decompiled-crushmap-filename} 

then check the file {decompiled-crushmap-filename} content is readable, if yes - recompile with crushtool -c
