Subject: About to orphan bcache-tools for Fedora
Date: Sun, 25 Sep 2022 15:14:34 +0200 [thread overview]
Message-ID: <68fe0b49-13ed-0565-0558-46ba0edd9a40@rolffokkens.nl> (raw)
Hi all,
In 2013 I took it upon me to include and integrate bcache-tools in
Fedora, which required tweaks in lvm2, util-linux and other packages.
With the help of the respective maintainers, it all got into good shape
in Fedora 21.
I have been using it myself ever since, but have been struggling
somewhat with my bcache on raid5 setup recent years. Not sure if the
combination was the cause of random filesystem corruptions, or other
hardware issues. For sure this PC had some PSU issues causing one of the
HDD's to frequently reset. But after replacing the PSU about a year ago
all HDD's have been rock steady. Ever since no usefull error messages
ever popped up, but these random filesystem corruptions have stayed. And
to be specific: only when using writeback caching, and mostly when doing
heavy writes. No useful data however to file a proper bug report.
Not being able to identify the cause, a month ago I decided to replace
bcache with lvm-cache (lvm-cache was no viable alternative in 2013).
Just to see if that solved the issue, or provided clues about the cause
of the issue. Not as easy to use as bcache (had to use LVM stacking to
use lvm-cache in my setup) but in the end it all works. And the
filesystem corruptions seem to be a thing of the past now. I decided to
cowardly walk away from the issues I've had for a while, I'm just too
happy it's stable now. This means that I won't be using bache anymore on
my daily driver.
Now on the other side, I also have a Dell Inspiron 5570 from 2017 laptop
that's using bcache and it has been running fine ever since. Different
hardware, simpler setup: no raid, just a ssd and a sata hdd. As long as
this laptop is alive I'm able to provide some form of support to Fedora
users, but after that.... any new laptop will just be plain SSD.
So I'm about to orphan bcache-tools for Fedora, meaning there will be no
maintainer. Before doing so I'm bringing it up here, maybe here's
somebody willing to adopt the Fedora package...
Cheers,
Rolf
