List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: nfs-bounces@lists.sourceforge.net Errors-To: nfs-bounces@lists.sourceforge.net NFSv3, udp, client=2.6.17.8, server=tru64 On the client I started to get some random ESTALE errors which disappeared quickly afterwards without a remount. The errors only occurred when typing stat .. in a subdirectory of a mountpoint. Doing ls -al in that subdirectory gave an ESTALE only on "..". I could even change directory to / and back without an ESTALE but the "stat .." command still gave an ESTALE. A "tcpdump -i eth0 udp port 2049 -n -s 1500" showed something which is unusual to my knowledge. The kernel tried to lookup "/" in the mount point as it seems: 16:42:03.644621 IP 172.17.1.64.3759242568 > 172.17.1.1.2049: 120 lookup fh 2956,259248/28524 "stat" 16:42:03.644967 IP 172.17.1.1.2049 > 172.17.1.64.3759242568: reply ok 116 lookup ERROR: No such file or directory 16:42:03.647345 IP 172.17.1.64.3776019784 > 172.17.1.1.2049: 112 getattr fh 2956,259248/2 16:42:03.647496 IP 172.17.1.1.2049 > 172.17.1.64.3776019784: reply ok 112 getattr DIR 1777 ids 0/0 sz 0x2000 => 16:42:03.648002 IP 172.17.1.64.3792797000 > 172.17.1.1.2049: 120 lookup fh 2956,259248/2 "/" 16:42:03.648244 IP 172.17.1.1.2049 > 172.17.1.64.3792797000: reply ok 116 lookup ERROR: No such file or directory 16:42:03.648440 IP 172.17.1.64.3809574216 > 172.17.1.1.2049: 112 getattr fh 2956,259248/2 16:42:03.648680 IP 172.17.1.1.2049 > 172.17.1.64.3809574216: reply ok 112 getattr DIR 1777 ids 0/0 sz 0x2000 => 16:42:03.648877 IP 172.17.1.64.3826351432 > 172.17.1.1.2049: 120 lookup fh 2956,259248/2 "/" 16:42:03.649110 IP 172.17.1.1.2049 > 172.17.1.64.3826351432: reply ok 116 lookup ERROR: No such file or directory 16:42:09.605452 IP 172.17.1.64.3879531864 > 172.17.1.1.2049: 116 access fh 3806,805074/16337 001f 16:42:09.605758 IP 172.17.1.1.2049 > 172.17.1.64.3879531864: reply ok 120 access c 001f -- Frank ------------------------------------------------------------------------- Using Tomcat but need to do more?
