Logical block size has type unsigned short. That means that it can be at
most 32768. However, there are architectures that can run with 64k pages
(for example arm64) and on these architectures, it may be possible to
create block devices with 64k block size.
For exmaple (run this on an
I have two queries:
1. We have an issue with device blacklisting. We add an entry in
/etc/multipath.conf" and do "service multipathd reload".
After this to check if device is blacklisted we issue "multipathd show

Sometimes I see that
When dm-writecache is used with SSD as a cache device, it would submit

scheduler, but this merging degrades performance.
This patch makes dm-writecache submit larger bios - we can submit large
bio as long as there is
