Hello, I'm compiling glusterfs for a debian squeeze. When I do a make command, I see These parameter: GlusterFS configure summary =========================== FUSE client: yes Infiniband verbs: yes epoll IO multiplex: yes argp-standalone: no fusermount: no readline: no georeplication: yes I would like to create a package that can be used both as a client and a server. I'm not interested on Infiniband, but I would like to know how to behave with the following parameters: argp-standalone: no fusermount: no readline: no can be ignored or shou...

Hello everyone! I'm playing with guestunmount and got the following issues: 1) guestunmount never returns 3 (not mounted) - i guess it's a bug at guestunmount.c:223 2) I don't know whether it's a bug in guestunmount or fusermount, but on my machine while executing > guestmount > guestunmount > guestunmount on second "guestunmount" I get "guestunmount: failed to unmount {...}: fusermount: failed to unmount {...}: Invalid argument" while, according to guestunmount.c, guestunmount should retur...

Since the first patch: - The program is now called 'guestunmount'. - I tested the --fd option and it appears to work. - You can now control retries / quiet. - Revised man pages. - Includes tests. I'm just running through the automated tests now. Rich.

...two ways: guestmount-cleanup --fd=<FD> mountpoint where it will monitor the pipe file descriptor <FD>. (I should note that I've never actually tested this code path). Or: guestmount-cleanup mountpoint where it immediately unmounts the mountpoint. In both cases it deals with fusermount retries. The patch is still large and clunky and it doesn't make FUSE that much easier to cope with. I suspect the way to go from here is to reimplement fusermount itself. It would, for example, be much better if we could get some information from fusermount about why it failed. That seems l...

...#39;t exist on Darwin. * src/launch-libvirt.c needs to #include <sys/un.h> for sockaddr_un. The rest of the issues have been mentioned in https://www.redhat.com/archives/libguestfs/2013-October/msg00042.html, and I've reused RWMJ's patches. * fuse/guestunmount.c uses Linux-specific fusermount and '-v' option for fuser. * src/proto.c -- From Apple's xdr.h: "If your code invokes an xdrproc_t callback, it must be modified to pass a third parameter, which may simply be zero." * OS X does not provide open_memstream(). * src/guestfs-internal-frontend.h and gnulib/lib/...

...and did a standard installation booting from the CDROM and getting the default packages from the server in the LAN. This worked fine. ----- When it came to test the installed packages i was always lucky except with the package fuse (fuse-2.8.3-1.el6.x86_64) which contains the binary /usr/bin/fusermount. This binary was installed without execute permission for everybody, so it could be invoked only by the userid root and members of the group fuse, which is not, what i had expected. suomi
