Re: [Libguestfs] [EXTERNAL] - Re: LIBGUESTFS mount disk failure

Hi Richard, Thank you for the response, will set both handler and let you know. when we try to execute guestfs_mount_local. Getting below error : [ 2023-09-19 13:34:05 ] errno: ( 0 ) : mount_local: unknown option 554101136 (this can happen if a program is compiled against a newer version of libguestfs, then dynamically linked to an older version)

Setup details : OS : (PRETTY_NAME="Red Hat Enterprise Linux 8.2 (Ootpa)") Guesfs.h version : 1.50 Guestfish version : guestfish 1.38.4rhel=8,release=15.module+el8.2.0+5297+222a20af,libvirt In Below scenario: 1. guestfs_mount_local_run 2. umount /mountpoint 3. Again, while trying to mount, after sleep of 20sec. Thanks RR -----Original Message----- From: Richard W.M.

To capture all messages you must set both together. If you can produce a single, short reproducer which uses both types of handlers and still prints to stderr, then I can look at that.
