...ng together? I remember something about turning oplocks off in samba, and while testing samba I noticed this [2010/08/27 17:30:59, 3] lib/util.c:fcntl_getlock(2064) fcntl_getlock: lock request failed at offset 75694080 count 65536 type 1 (Function not implemented) But I also found out about the flock option for lustre. Should I set flock on all clients? or can I just use localflock option on the fileserver? David -- Personally, I liked the university.

This meant we started using a 32-bit struct flock with 64-bit fcntl numbers. Disable the kernel's definition of struct flock and define it ourselves with...

Hi, I'm writing an application with C under Linux and I'm trying to use the flock system function to lock a file of an NT4 Server over Samba. The problem is that the lock works well within the same machine but if it is a process on another machine (the same program) the one that tries to access the locked file, the process is not blocked until the lock is released but given full...

...ected, and applications using the file system locally and remotely see the locks set by the other. However, if a program on the Windows client opens a file with a share mode that denies access to other processes, I can't seem to detect this in a local Linux process, either with fcntl() or with flock(). I included the test programs I used below. I have seen references that this should be possible (http://lists.samba.org/archive/samba/2004-February/080455.html last paragraph) but I may be misunderstanding things. strace on the smbd process handling the request from the Windows client shows this...

Hi - I'm trying to verify if OpenSSH/SFTP will in fact lock files with advisory file locking in Linux. I can test locking with the linux "flock" command to verify that file locking does work - but when I upload or download a file with SFTP it will not detect a lock. I'm asking about Linux specifically because about a year ago I was doing a similar process in Solaris 9 and it seemed to work. OS'n I've tried this on- RH...

Everybody wants to lock differently 1) procmail (delivering for sendmail), which seems to want to use dotlocking, fcntl and lockf locking; for whatever reasons, the compile time tests seem to disallow flock. 2) UWIMAP which according to wiki.dovecot.org/Migration/UW uses: mbox_read_locks = flock mbox_write_locks = dotlock flock 3) I want to run dovecot in the same environment as I switch over, for which the locking strategy is supposed to be (according to http://wiki.dovecot.org/MboxLocking) mbox_re...

While experimenting a bit, I found that for some reason, locking indexes with flock is problematic, but only if user is taken from passwd-file. The host system is openbsd 3.9, dovecot's configuration is added at the bottom. Authentication is from two places - first from mentioned passwd-file, then from passwd file using bsdauth (in this case, there're no problems with...

Hi, I see samba with ctdb locking has following mapping when kernel oplocks = yes. share mode reservations = flock(2) posix byte range locking = fcntl(2) SMB locks (mandatory) = ctdb using brlock.tdb oplocks = fcntl(2) using F_SETLEASE Am I correct or I am missing something? I hope only SMB range locks are implemented with tdb, all else are being used from filesystem. What happens if flock or fcntl...

...box with SLES 12. All is working fine with our NAS NFS Shares. We are now trying to integrate new NFS Shares from an archive provider. We have some problems with samba not responding, when accessing files on these archive NFS shares. We have done some Samba-Debugging and found out, that the call to flock in source3/lib/system.c (kernel_flock) do not return and is blocking samba! Is it necessary to use file locking when using Samba as fileserver for readonly access with NFS shares? Can I disable locking with #define HAVE_KERNEL_SHARE_MODES 0 in config.h. What are the consequences? Kind regards Geo...

Hi, tl;dr summary of below: flock() works, but what does it take to make sync()/fsync() work in a 3 node GFS cluster? I am under the impression that POSIX flock, POSIX fcntl(F_SETLK/F_GETLK,...), and POSIX read/write/sync/fsync are all supported in cluster operations, such that in theory, SQLite3 should be able to atomically lock...

Hi list, as I know from the README in the source files OCFS2 does not support cluster aware flock. Our web developers have to use the php flock() function. There is a second method how php can handle locking - via the fnctl() function. Will this be supportet? I assume that OCFS2 supports the c-function open() mit O_CREATE as well as O_EXCL. Am I right?
