I don't suppose there is an easy way to query xfs and find out if it can supportOn Thu, 2008-02-28 at 12:09 +1100, Barry Naujok wrote:Lazy superblock counters was released into mainline in 2.6.23-rc1.Some distros are still running an older kernel (2.6.22 for example) and with(many distros?

This should give enough time for distro kernels to catchup.Hmm, that still seems pretty soon to me. I'd have thought you'd at least want to wait until most of the distributions (esp. SUSE for you guys) have released versions that have kernels sufficiently recent that the default mkfs will work. Otherwise this will be a recurring problem.
the lazy SB option?
