--- name: "nfstest_pnfs" section: "1" platform: "linux" package: "nfstest" version: "3.2-3" release: "Debian 13 (Trixie)" platforms: ["linux"] url: "https://new.carta.tech/nfstest_pnfs" --- # nfstest\_pnfs(1) Basic pNFS functional tests ## NAME nfstest\_pnfs - Basic pNFS functional tests ## SYNOPSIS nfstest\_pnfs --server \ \[options\] ## DESCRIPTION Verify basic pNFS functionality for file (both READ and WRITE), including opening a second file within the same mount and having a lock on the file. Also, verify basic pNFS functionality for a file opened for both READ and WRITE while reading the file first and then writing to it or the other way around by writing to the file fist and then reading the file. These tests verify proper functionality of pNFS and NFSv4.1 as well. ## OPTIONS - \--version show program's version number and exit - \-h, --help show this help message and exit - \-f FILE, --file=FILE File where options are specified besides the system wide file /etc/nfstest, user wide file $HOME/.nfstest or in the current directory .nfstest file ### NFS specific options: -
