[opensuse] slow nfs to chmod g+s share
Hi 12.1 server and clients We have a Dropbox-like folder under /home with chmod g+s drwxrwsr-x 2 root suseusers 4096 2011-08-01 18:08 . Writes to that folder are noticeably slower, e.g. editing large jpg's, when compared to writing the same file to your own folder. When the lan is busy, it can take several seconds to save a file. Over time, this gets annoying. I'm almost certain that this is the g+s as when I remove it, we can all rw at normal speed, but of course we can't share the files. I've tried with and without krb5 and async. Are there any other tweaks I'm missing here? rsize and wsize? acl's (whatever they are!)? Any suggestions gratefully received. Thanks, L x Server: /etc/exports /home 192.168.1.0/24(rw,sec=none:sys:krb5:krb5i:krb5p,no_subtree_check,insecure) Client: mount gives: hh3:/home/ on /home type nfs4 (rw,relatime,vers=4,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=krb5,clientaddr=192.168.1.3,minorversion=0,local_lock=none,addr=192.168.1.3) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Do you know that it is NFS, rather than whatever the actual filesystem is, that causes the problem? What is taking the time? Is the server busy? Is the client busy? Is the network busy? What does strace say on any processes actively involved, for example? Have you tried an NFS3 or a CIFS/SAMBA mount instead? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
