Subject: [PATCH 284/284] posix: log aio_error return codes in
|
|
|
50dc83 |
posix_fs_health_check
|
|
|
50dc83 |
|
|
|
50dc83 |
Problem: Sometime brick is going down to health check thread is
|
|
|
50dc83 |
failed without logging error codes return by aio system calls.
|
|
|
50dc83 |
As per aio_error man page it returns a positive error number
|
|
|
50dc83 |
if the asynchronous I/O operation failed.
|
|
|
50dc83 |
|
|
|
50dc83 |
Solution: log aio_error return codes in error message
|
|
