Issue #2499 has been updated by Nerzhul.
Hi Antonio, I use a FreeBSD cluster which mount it's 3rd party FS via NFS share under DFly (/usr/local). The system also mount /usr/ports/distfiles and /var/db/pkg. /var/db/pkg contain a Sqlite DB for pkgng. in /usr/local we have all 3rd party compiled ports for clustered web servers, with all web user datas in /usr/local/www/* (except pg and my DB which are on another server) and some different websites (owncloud, dokuwiki...) The goal is to have a main freebsd which only mount required 3rd party folders, machine extensible and exactly same datas. (the goal is 3 great Apache). As Francois Tigeot adviced me, i have disabled lockd via /etc/fstab nolockd option for /usr/local and /usr/ports/distfiles which are static, but not for /var/db/pkg which contains a sqlite db. Then lockd problem is partially resolved. But it slows my "pkg info" command and other "pkg xx" commands (like portmaster uses). ---------------------------------------- Bug #2499: DRAGONFLY_3_2 lockd not responding correctly http://bugs.dragonflybsd.org/issues/2499 Author: Nerzhul Status: In Progress Priority: Urgent Assignee: Category: Target version: Hello, i must use lockd for concurrent access on a webserver with nfs extended storage. There is some concurrent access and lockd isn't responding correctly. On the NFSv3 client, timeout appears and console logs: nfs server A.B.C.65:/nfs/fbsd_pkg: lockd not responding nfs server A.B.C.65:/nfs/fbsd_pkg: lockd not responding nfs server A.B.C.65:/nfs/fbsd_pkg: lockd is alive again nfs server A.B.C.65:/nfs/fbsd_pkg: lockd not responding nfs server A.B.C.65:/nfs/fbsd_pkg: lockd not responding nfs server A.B.C.65:/nfs/fbsd_pkg: lockd is alive again nfs server A.B.C.65:/nfs/fbsd_pkg: lockd not responding nfs server A.B.C.65:/nfs/fbsd_pkg: lockd not responding nfs server A.B.C.65:/nfs/fbsd_pkg: lockd is alive again nfs server A.B.C.65:/nfs/fbsd_pkg: lockd not responding nfs server A.B.C.65:/nfs/fbsd_pkg: lockd not responding nfs server A.B.C.65:/nfs/fbsd_pkg: lockd is alive again nfs server A.B.C.65:/nfs/fbsd_pkg: lockd not responding nfs server A.B.C.65:/nfs/fbsd_pkg: lockd not responding nfs server A.B.C.65:/nfs/fbsd_pkg: lockd is alive again nfs server A.B.C.65:/nfs/fbsd_pkg: lockd not responding nfs server A.B.C.65:/nfs/fbsd_pkg: lockd not responding nfs server A.B.C.65:/nfs/fbsd_pkg: lockd is alive again After "netstat -an -f inet" i see there is a queue on rpc socket netstat -an -f inet Active Internet connections (including servers) Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp4 0 0 A.B.C.65.nfsd WebCluster1.977 ESTABLISHED tcp4 0 0 A.B.C.65.nfsd WebCluster1.611 ESTABLISHED tcp4 0 0 localhost.smtp *.* LISTEN tcp4 0 0 *.ssh *.* LISTEN tcp4 0 0 *.1017 *.* CLOSED tcp4 0 0 *.1020 *.* LISTEN tcp4 0 0 *.nfsd *.* LISTEN tcp4 0 0 *.1023 *.* LISTEN tcp4 0 0 *.1022 *.* LISTEN tcp4 0 0 *.sunrpc *.* LISTEN tcp4 0 0 A.B.C.65.nfsd A.B.C.96.811 ESTABLISHED tcp4 0 0 A.B.C.65.nfsd WebCluster1.972 ESTABLISHED tcp4 0 48 A.B.C.65.ssh 129.175.196.190.60067 ESTABLISHED udp4 0 0 *.918 *.* udp4 0 0 A.B.C.65.1028 ntp.u-psud.fr.ntp udp4 456 0 *.1017 *.* udp4 18656 0 *.1018 *.* udp4 0 0 *.nfsd *.* udp4 0 0 *.1021 *.* udp4 0 0 *.1020 *.* udp4 0 0 *.1022 *.* udp4 0 0 *.sunrpc *.* When i see that, i make tcpdump -nni em0 to see what's happening: 22:12:42.781597 IP 10.117.100.95.961 > 10.117.100.65.1017: UDP, length 212 22:12:48.801935 IP 10.117.100.95.961 > 10.117.100.65.1017: UDP, length 212 22:12:54.669917 IP 10.117.100.95.961 > 10.117.100.65.1017: UDP, length 212 22:13:00.148965 IP 10.117.100.95.961 > 10.117.100.65.1017: UDP, length 212 After a little time, lockd respond to all request, but many failed because of timeout On the dragonflyBSD server i can see this in /var/log/messages Jan 21 22:14:19 webfiler1 rpc.lockd: duplicate lock from WebCluster1.srv.

I think there is a problem on DragonFlyBSD which queue many lockd requests. -- You have received this notification because you have either subscribed to it, or are involved in it.
