IBM Tivoli Storage Manager for UNIX and Linux Backup-Archive ...

You can use this option to mitigate the default behavior of status calls on filesystems. For example, if an NFS file system is stale, a status system call will betimed out by NFS (softmounted) or hang the process (hardmounted).When the value of this option is changed to a value other than zero, a new threadis created by a caller thread to issue the status system call. The new thread istimed out by the caller thread and the operation can continue.Note: On Solaris and HP-UX, the nfstimeout option can fail if the NFS mount ishard. If a hang occurs, deactivate the nfstimeout option and mount the NFS filesystem soft mounted, as follows:mount -o soft,timeo=5,retry=5 machine:/filesystem /mountpointThe parameters are defined as follows:soft Generates a soft mount of the NFS file system. If an error occurs, the stat()function returns with an error. If the option hard is used, stat() does notreturn until the file system is available.timeo=nSets the time out for a soft mount error to n secondsretry=nSet the internal retries and the mount retries to 5, the default is 10000.Supported ClientsThis option is for all UNIX and Linux clients. The server can also define thisoption.Options FilePlace this option in the dsm.sys file within a server stanza or the client options file(dsm.opt).Syntax►► NFSTIMEout number ►◄ParametersnumberSpecifies the number of seconds the client waits for a status system call on afile system before timing out. The range of values is 0 through 120; the defaultis 0 seconds.ExamplesOptions file:nfstimeout 10Command line:-nfstimeout=10This option is valid only on the initial command line. It is not valid in interactivemode.Related information354 IBM Tivoli Storage Manager for UNIX and Linux Backup-Archive Clients Version 6.1: Installation and User’s Guide
