Hello,
I am trying to get some more information about the following issue:
# strace -p 2256 attach: ptrace(PTRACE_ATTACH, ...): Operation not permitted
I am trying to trace an mdadm re-sync pid and I keep getting the above error.
I believe the MD re-sync process is actually a kernel thread - and you can't strace kernel threads.
