Support for Journalling Flash File System

Latest response

  I would like to have support for Journalling Flash File System v2 in Red Hat Enterprise Linux 7.

 

  I have servers in my datacenter which use an SLC NAND SSD as the system-drive (i.e. the drive which holds the /boot and / partitions), with the other partitions (i.e. /srv, /root, /home and /var ) housed on a Fibre Channel LUN. Although the /boot partition has to use the ext2, ext3 or ext4 filesystem, it would be very useful to have the / partition (which contains directories such as /bin, /etc, /lib, /proc, /sbin, /sys, /usr and /temp) use the JFFS2 filesystem, in order to optimize the use of the SSD.
