rpm -Uvh http://elrepo.org/elrepo-release-6-4.el6.elrepo.noarch.rpm
yum --enablerepo=elrepo-testing install kmod-flashcache flashcache-utils

flashcache_create -p thru ssdcache /dev/sdb /dev/sda

FATAL: Error inserting flashcache (/lib/modules/2.6.32-042stab061.2/extra/flashcache/flashcache.ko): Invalid module format

Right thanks. I found the right kernel. It installs fine now. However, it now says
device-mapper: create ioctl on devcache failed: Device or resource busy

Please help.

Edit: I've unmounted the said partition. I don't get the issue.

Hi, I finally got it working, however on reboot, fsck fails and it says the ssd device has a corrupted partition table or superblock. Do you know what happened? Thanks.

Hi, I think I'm missing the script for redhat. I don't know what to put for MOUNTPOINT and FLASHCACHE_NAME. The guide isn't clear. Please help.
