Description Kyrre Ness Sjøbæk 2004-10-15 15:34:32 EDT
Description of problem: At thursday morning, nfs suddenly became *very* slow. So slow that loging in to the boxes took 3 minutes instead of 5 secounds - this problem has been windows-only so far (luckily i don't administer thos e boxes). After some digging, if found that the problem probably was do to slow responce from stat() - ls (which is an alias to ls --colours) tok 10 secounds in /home, while /bin/ls tok 0.01 secound. The machines mount their /home over version 2 nfs from a debian box, My out-of-date laptop do not have any problems, neither did the boxes have before the upgrade. It seems like transfer rate is okay, but opening/closing a file takes _a while_. Version-Release number of selected component (if applicable): nfs-utils 1.06-22.i386 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
Comment 1 Kyrre Ness Sjøbæk 2004-10-15 15:36:13 EDT
BTW how do i rollback (ie. where do i find a functional RPM? CD's?) and prevent yum from re-installing the faulty RPM? i use "nightly yum update". Guess i shouldn't...
Comment 2 Steve Dickson 2004-10-15 17:57:17 EDT
Would it be possible to get a ethereal trace and the output of nfsstat -rc?
Comment 3 Kyrre Ness Sjøbæk 2004-10-16 14:00:37 EDT
sure, but i have to downgrade most of the boxes asap. How do i isolate the output to NFS only?
Comment 4 Steve Dickson 2004-10-16 20:27:17 EDT
Try the capture string of "port 2049"
Comment 5 Kyrre Ness Sjøbæk 2004-10-18 10:57:50 EDT
Forget it. My mistake. The problem was not NFS, it was LDAP. Which matches with the libuser libary was just updated. Sorry!
