Hi All

how to extend the /usr file system on a server which is not having online JFS?

Thanks

You will have to umount /usr and do lvextend and extendfs. But in multiuser mode, you will have lots of apps/programs accessing /usr. So boot into single user mode and do it.

Hi:

To extend '/usr' in the absence of OnlineJFS, boot into single user mode. The commands you need are found in '/sbin' since '/usr' will not (and cannot) be mounted to extend your filesystem in the absence of OnlineJFS.

Use 'lvextend' to increase the size of the logical volume that hosts the '/usr' filesystem. Then, use 'extendfs' to enlarge the actual filesystem.

Reboot the system. This is the easist way to restart and bring your server back to a production state.

Regards!
