[ccache] ccache error: Failed to create temporary file... Read-only file system

[Raju C K]

Hi,
I need a help.
I am trying to build bootimage from kernel sources for android. I have ccache enabled with max_size 90G.
The ccache version is 4.2.1

Compilation stops, throwing a "ccache error: Failed to create temporary file /home/ck/.ccache/tmp/tmp.a.Xdafd Read only file system".

Can anyone help or show some resources to read/refer ?

Rgds,
CK
