Problems with F2FS.
I’ve had a rather strange issue with F2FS in NIxOS that actually forced me to re-partition a particular machine.
Said machine had an NVME SSD and this was a fresh install of 19.03.
Story is as follows
Installs NixOS with a completely blissful joy
(imagine Julie Andrews the hills are alive style)
Boots NixOS and things are kinda weird
fsck.f2fs would stall for about >=20s in an almost consistent manner.
Anytime I would do
nixos-rebuild * and boot the new generation it would stall this way.
fsck would take more and more time after more rebuilds and reboots.
Even more so if I switched a kernel.
- Can’t boot because
This was understandably frustrating for me.
However I still held true.
- Does some seeking
Things I noticed
Note this a wasn’t a particularly invested investigation.
I could always change the filesystem and move on.
But I was really confused by how it appeared that
fsck was an aggressor here.
I thought to skip
fsck and see if we could move on, but I couldn’t achive this for some reason, even with
Long story short did some diagnostics and there wasn’t anything wrong.
Didn’t use f2fs.
Not particularly the one I wanted, but I’ve tried other filesystems and haven’t had any problems.
So maybe there’s a problem in NixOS?
Hardware could be at fault, I doubt it though, but I wouldn’t wish this experience on someone.
I’d be consenting to it by means of complacency.
I’ve posted this to inquire if anyone else has had these issues with F2FS.
