[Gluster-users] Regarding GlusterFS dependency on Linux Kernel Versions

[Ric Wheeler]

There are key kernel bug fixes and things that significantly help gluster run 
properly, especially in areas like FUSE and the IO stack.

In general, the more modern the kernel, the better the chance that you have all 
of those fixes in.

A side note on commercial versions of linux is that the kernel version number 
(3.10 in the example) is not really indicative of what fixes might have been 
backported to that kernel. Commercial linux vendors like Red Hat and Suse, etc, 
all work to chase down the critical issues and get them out even on older kernel 
versions.  Best to check with the vendor in those cases.

Regards,

Ric
