For those involved in the bcache support in storage-ng, this is Coly's answer to the question about the current status in all archs. -------- Forwarded Message -------- Subject: Re: Fate#325346 - bcache in non-x86_64 architectures Date: Sat, 2 Feb 2019 00:35:11 +0800 From: Coly Li <ourbcacheperson@abc.de> On 2019/2/1 5:56 下午, Ancor Gonzalez Sosa wrote:
By the way, Coly, I have a question about that. Assuming bcache is not production-ready in all architectures (which may be true or not, that's still an open question) - Are the bcache-tools available in all architectures, including those in which the technology doesn't work that well?
Bcache-tools can run on non-x86_64 platform, at least other people and I run them on s390x. The problem is, bcache code, everywhere, assume the machine is x86_64, even in formatting a bcache device, it does not handle bit order in meta data structures, and the checksum calculation order is wrong on big endian machines. So I would answer, bcache tools can run on all architectures, but they are only available (behave correctly) on x86_64 at this moment.
