Some questions: - What other changes have taken place on the VM system? - How big are the virtual machines? - Do other commands on the affected Linux guests respond quickly (what about on the NFS server(s))? - How much storage does your VM system have? - What are the SRM settings for your VM system? (Q SRM from an apporpriately privileged user) - What does #CP IND Q report when the hang is happening? - Do you have a performance tool on your system?
Neale -----Original Message----- Hello, We have a filesystem which is shared by 4 Linux guests via NFS. We have been using this setup for quite some time. Recently we've seen 2 cases where access to the NFS file on 1 or more of the non-owning guests began to slow down. A "df" command on the effected system would stop before the NFS file and hang for >10 seconds. We've stopped all the tasks using the file, unmounted, and remounted it, with the same result. The only way to resolve the problem was to shutdown and IPL the effected Linux guest(s). The owning guest, i.e. the one running the NFS server, never had to be bounced. The network setup used for these mounts is a Guest LAN. Linux is SLES8 SP2, VM is V5.1. We take all the defaults for rsize, wsize, etc. in /etc/fstab for the mount. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
