TIL you can't resize dm-cache's underlying volume >.<

Maybe using lvmcache wasn't the best idea...

Can we have overlayfs but copy-up is triggered by reads too, not just writes?

hmm actually that wouldn't do the trick either, I need write-through.

Or even an invalidating write-around.

I tend to dump a bunch of stuff on my NAS only to never look at it again.

So it looks like if I upgraded to Debian 12 I could resize cached LVs without any issues.

But I vaguely remember Debian 12 drops one of the packages I need... argh...

Right, cadvisor.

There's no cadvisor in Debian 12.

@wolf480pl You can't install it separately?

@sjb

$ ldd /bin/cadvisor
linux-vdso.so.1
libpthread.so.0
libdl.so.2
libzstd.so.1
libc.so.6
/lib64/ld-linux-x86-64.so.2

🤔

I guess I could just grab or build any cadvisor binary out there, put it in an otherwise empty .deb, and it'd work, it's not like these libs have backwards-incompatible changes often...

@sjb oh, I forgot I'm actually using different cadvisor in /usr/local/bin which I built from source becaues the one in debian had a bug... duh...
