Red Hat Bugzilla – Bug 571555
nfs (client-fc11) nfs server (fc-12), intermittent stall/hang find command on directory.
Last modified: 2010-03-09 14:51:13 EST
Description of problem:
doing: while [ 1 ]; do find /my; sleep 5; done
the find hangs in a ps: S state
lsof shows the a cwd to different place, so I've been counting out some sort or
garbage character stream.
Version-Release number of selected component (if applicable):
Linux n0.localdomain 126.96.36.199-105.2.23.fc11.x86_64 #1 SMP Thu Feb 11 07:06:34 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux
[gartim@n0 ~]$ rpm -qa |grep -i nfs
Linux genepi1.berkeley.edu 188.8.131.52-174.2.22.fc12.x86_64 #1 SMP Fri Feb 19 18:55:03 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux
[gartim@genepi1 ~]$ rpm -qa |grep nfs
see above, happens on the 2nd+ time usually
Steps to Reproduce:
just to list all dirs/files on the nfs volume
thought it could be the command (find), but tried tree and got the same results. Considered it may be the network, so I checked the routing tables, look ok, also switched the mount from one interface to another and got the same results. I do have switch (24port) that i haven't tried removiing, but there is not much traffic on it yet. I plan to try a xover cable test, removing the switch, maybe tomorrow. The other option is to upgrade (in a hurry) to fc12. thanks much for any help/guidance, i realize I havent provided any network traces -- hard because the problem may occure after it has done a full listiing of the nfs volume -- some 2tb+ of data/dir listiings.
this is a user error. ends up the switch was mis-configured. Thanks anyway.
