Get started with XCP
The XCP NFS chmod command scans and changes the file permission of all the files for the given directory structure. The 'chmod' command requires mode or reference, NFS share, or the POSIX path as a variable. The XCP chmod command recursively changes the permissions for a given path. The command output displays the total files scanned and the permissions changed in the output.
xcp chmod -mode <value> <source NFS export path>Show example
[root@user-1 linux]# ./xcp chmod -mode <IP address>:/source_vol Xcp command : xcp chmod -mode <IP address>://source_vol Stats : 6 scanned, 4 changed mode Speed : 1.96 KiB in (2.13 KiB/s), 812 out (882/s) Total Time : 0s. STATUS : PASSED [root@user-1 linux] #
