are bogus. When did you last tune the ext4 cache size or timeout? Don't come
up with ext4 being kernel vs. userspace fs. It was their decision to make it
userspace, so don't blame me. As a fs with networking it has to take the
comparison with nfs - as most interested users come from nfs.
Ever heard of fsc (FS-Cache),
To my knowledge there is no persistent (disk-based) caching in glusterfs at
all ...
Correct, but just a while ago you questioned the idea of caching in the
filesystems ("When did you last tune the ext4 cache size or timeout").
It's amazing that you changed your mind so fast.
[cutting your ignorance about iSCSI and pretending you know it well]
I don't think there can be any constructive discussion with you, sorry.
If you found a bug, and even more, it's repeatable for you, please file
a bug report and describe the way to reproduce it.
Since the problems happen so often for you, I'm sure it shouldn't be so
hard to produce a good test case.
Initiating flame discussions is not really a good development model.
