While doing migration, sometimes found suspend lock file was not unlinked in previous operations, then there is an obsolete lock file in place, which causes the current and later migration cannot get lock. That happens seldomly but do happen. After checking the source code, I found there are some places that potentially cause lock file unlinked, including: 1) in lock_suspend_event() function,

php-5.3.3-3.el6_2.6.x86_64 2.6.32-220.4.2.el6.x86_64 After some testing we moved our production PHP intranet site from an old server to a new CentOS 6.2 instance running the mentioned versions. At first it worked well and then user's started to experience a hung site. Upon some digging it appears that the PHP module is getting stuck in a race condition regarding the sessions file - [root at

Are their issues with Samba and Lustre working 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

/etc/postfix/main.cf.default: mailbox_delivery_lock = flock, dotlock Is flock equivalent to dovecot's fnctl locking? For mbox what type of locking settings should I be using? (No NFS, only local filesystem.) Warren Togami warren at togami.com

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

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

There are three applications that have their mitts on files on my mail server, which is running AIXV5.3 and UWIMAP and mbox format. The mail folders and INBOXES are native to that machine, but also are NFS exported to a login server and a mailing list server. All three machines are running the lockd daemon. Everybody wants to lock differently 1) procmail (delivering for sendmail), which

Hi all, I have some machines running FreeBSD and dovecot deployed. User's home dir is on NFS mount and I've found that dovecot only works with dotlock file locking mechanism, fcntl and flock failed. Now it causes problem with thunderbird (thunderbird is cachine connections) waiting forever and I noticed that dovecot is trying to acquire a lock but unsuccessful since the lock file is in

Hello all, First of all, apologies if this isn't the right location for this question, I couldn't find a CTDB specific mailing list or IRC so I figured the general one would be appropriate. Please let me know if this question is better placed elsewhere. I'm trying to test clustered samba and have a two node CTDB setup (Following the guide here:

A couple of days ago, we noticed the following message appearing in syslog: Aug 14 15:09:35 zadok smbd[16067]: tdb(/var/lock/samba/locking.tdb): expand_file write of 8192 bytes failed (No space left on device) Similar messages would show up for several of the files under /var/lock/samba.

I have Dovecot 1.0 in trial use by the IT staff, and have some locking questions Background, the mail server runs procmail, sendmail and NFS exports the user homedir and mailbox to a) a login shell host and b) a mailing list services host. It runs UWIMAP on the usual ports and dovecot on a arbitrary port number. Because of concern with NFS and file access contention. I have the following

I'm running rsync 2.5.6 on windows (via cygwin) and I've had other processes try to open the same files as rsync, but could not get through sometimes. Does rsync place a shared lock or an exclusive lock on the files it will copy from? I checked into the sources but did not find any use of flock() which could specify either LOCK_SH or LOCK_EX, so I'm not sure what the open() does when

Hi, i'm searching for best practice in configuration a dual head nfs / samba server. At the moment samba 3.6.x is used, an yes i'll know it is EOL. We have the problem if the windows client open a file, the aix nfs client doesn't recognize the lock and overwrite the file. Is there a solution for this or is this the hell of nfs locking ;-) best regards Michael -- Michael Wandel

http://dovecot.org/tools/nfstest.c I wrote a test utility that tests different ways to flush NFS attribute cache and data cache. Please test in your NFS setup and show me the results, so I can make Dovecot v1.1 works well with NFS. Run the test several times (3 should be enough) to make sure the output stays the same, because the attribute cache flushes might incorrectly say "OK". And

Can anyone help with some pointers to debug a problem with Samba and CTDB with smbstatus traversing the connections tdb? I've got a new two node cluster with Samba and CTDB on AIX. If I run smbstatus when the server has much user activity it hangs and the node it was run on gets banned. I see the following in the ctdb log: 2014/10/29 11:12:45.374580 [3932342]:
