Hello, I'm using samba 4.7.3 to run an AD and I'm currently having issues with the MIT kerberos because it stops some time after starting (and apparently working correctly) without logging nothing out of the ordinary. My setup has 2 DC: one in an ubuntu 12.04 with version 4.1.9 (which we're migrating from) and the one I mentioned in CentOS 7 (which will be the only DC in the future).

Hi Slight problem - linux 2.4 running dovecot, Solaris 2.8 home directory server. Full lockd support etc. I had to make the following code patches (at end of mail for clarity) to get dovecot to read the users mbox files at all. 1) fcntl with F_SETLKW will not work against a Solaris 2.8 server as proved with a small test program. Other forms of fcntl (ie F_SETLK) are OK. I noticed there are some code witches, but setting mbox_lock_timeout=0 only seems to knock one of the fcntl's over to F_SETLK 2) O_CREAT | O_EXCL are documented not to w...

Hi all, tracing a couple of reports here (on a somewhat older version of OCFS2, with a user-space/pacemaker/dlm_controld.pcmk stack) where we see fnctl(F_SETLK) return ENOSYS. This happens after a node has failed/been fenced and recovered. It affects only individual mounts, not the whole system. The only code path that I can see so far that could lead to ENOSYS being returned here is from within dlm_controld:process_plocks() if disable_plocks == 1. But I...

..., RSAFE]. If F_GETLK returns a conflicting lock, set RSAFE to one less than the lower bound of the conflicting revision range and retry. (Multiple retries may be necessary because it is unspecified which of multiple conflicting locks F_GETLK will return.) Once a lockable range has been found, use F_SETLK to acquire an exclusive lock on it. This may fail in an unlikely race with a reader; if it does, continue to back off RSAFE with F_GETLK. Remember RSAFE. 2) In the reader: Once the version file has been read, attempt to acquire a shared lock on the current revision. This may fail if a new revisi...

Greetings, We use NFSv4 on our cluster and perform distributed indexing (well, we used to on our previous system which used a simple touch() locking mechanism). I'm having a spot of bother getting Xapian to obtain a lock (hangs on fcntl64()). I've read http://trac.xapian.org/wiki/XapianOverNFS and other list posts, and noted that a lock daemon should be running to allow locks

Hi, When are client sessions closed? Let me explain what I'm trying to do... we're in a School district and we try to stop kids logging more than once. They way I did this before was to dump the active sessions from our previous Server2003 fileserver into a file once a minute and process it with a Perl script to check who was connected from where, rebooting machines remotely as

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 the file (or a subset of page), modify pages, flush the pages to gluster, then release the lock, and thus satisfy the ACID property that SQLite3 appe...
