Hi all As there seem to be no RPMs for version 5 in available repositories, I tried to build the RPMs myself but get stuck at 79% (note I’m not an experienced developer so this may be a simple question). [ 79%] Linking C shared library libganesha_nfsd.so ../os/CMakeFiles/gos.dir/linux/acl.c.o: In function `acl_get_fd_np': /root/git/nfs-ganesha/src/os/linux/acl.c:44: undefined reference to `acl_get_fd' /root/git/nfs-ganesha/src/os/linux/acl.c:57: undefined reference to `acl_get_file' ../os/CMakeFiles/gos.dir/linux/acl.c.o: In function `acl_set_fd_np': /root/git/nfs-ganesha/src/os/linux/acl.c:79: undefined reference to `acl_set_fd' /root/git/nfs-ganesha/src/os/linux/acl.c:92: undefined reference to `acl_set_file' collect2: error: ld returned 1 exit status make[2]: *** [MainNFSD/CMakeFiles/ganesha_nfsd.dir/build.make:754: MainNFSD/libganesha_nfsd.so.5.1] Error 1 make[1]: *** [CMakeFiles/Makefile2:1922: MainNFSD/CMakeFiles/ganesha_nfsd.dir/all] Error 2 make: *** [Makefile:156: all] Error 2 Googling the problem essentially returns Q&As from 2007 with little to no useful info ...…. Any suggestions (or pointers to already built binaries) ?? Regards Torben ______________________ Dr. Torben Kling Petersen Distinguished Technologist +46-704 393 240 [image001.png]

Re: intermittent problem with NFS

by Frank Filz

Hello, You may be running into a common problem with NFS. A common problem is the client doesn’t get any indication it should invalidate its cache of directory entries. Unless the client does something in the directory so it receives new attributes from the server, it will delay updating its cache. Depending on your workload you might have luck with reducing or eliminating the attribute cache delay. You can eliminate it entirely with the noac mount option, or just reduce or eliminate it for directories with acdirmin and acdirmax (check “man 5 nfs” for details). At least with a single Ganesha instance, you aren’t dealing with basically the same problem between Ganesha instances… Frank Filz From: Renaud Fortier [mailto:renaud.fortier.1@ulaval.ca] Sent: Thursday, April 20, 2023 5:05 AM To: support(a)lists.nfs-ganesha.org Subject: [NFS-Ganesha-Support] intermittent problem with NFS Good morning, I have an intermittent problem that I can not solve and today I ask for your help because I have no more idea. I have two Apache/PHP web servers (the clients) that use GlusterFS volumes via NFS (NFS-Ganesha) as data disks. The problem is that sometimes files saved to the server via PHP applications are not visible. Sometimes it's one of the two clients who doesn't see them, other times it's both clients. It's random because in general, everything works well. When I realize that a file is in trouble, I go to the directory “cd /data/folder” and I do an “ls -l”. I have no warnings or errors in the log files (clients and servers) Do you have any ideas or ways to help me solve this problem? Here's some informations.
