Hello Mikhail, your plan to switch to ext4 is the best thing you can do for private usage. Unfortunately there is no way to reformat the FS without deleting everything that is on the partition. Btrfs shows many many issues for a normal user and tends to exhibit exactly those problems you are experiencing right now. Search on the net for ext4 and problems during the last 2 years and do the same for btrfs for the last two years and you'll understand what I mean. The main property of btrfs is being broken. And the tools that are at hand are neither easy to use nor secure. You should never use fsck for example - so, the command apparently most familiar to anybody should not be used ... There are many people around that will tell you how wonderful btrfs is - but no one of them will fix the crap on your harddisk for you the very moment btrfs starts making trouble. My two cents after a bunch of reinstalls with ext4 - and never had had any problems since then ... for years ... guess why. This does not actually help, I know, as you are kind of stuck, but the best thing you can do is get a cheap usb stick, format it ext4, put the data from your root disk on it, reformat your root disk ext4 and copy the data back to it. Hope this helps regards Dieter Am Montag, 13. November 2017, 21:18:49 schrieb Mikhail Ramendik:
Hello,
I trued to upgrade to 42.3 and the process failed because the root file system was full. df -h shows it full at 40 gigabytes.
But... with du, I can only find the usage of 15 gigabytes.
Moreover. I found 3 gigabytes in /root that could be deleted, and promptly deleted them. But df -h is not showing any more space! I am in the command line under root, no trash system anywhere.
I suspect snapshots are the problem, because I accepted the default of btrfs for the root filesystem. So I could just delete some old snapshots.
But how do I list the snapshots? And how do I remove them? Somehow when I google this I can't find anything.
I mean, I did find
btrfs subvolume list /
and it lists quite a few lines like:
ID 996 gen 288328 top level 258 path @/.snapshots/558/snapshot
But I can't find a way to delete these snapshots. when I do
btrfs subvolume delete @/.snapshots/558/snapshot
I get "no such file or directory".
So how can I delete snapshots? Even better. how do I find out which snapshots are made when and include what, so I can delete those I certainly don't need?
I am tempted to reinstall with an ext4 root file system, but I do not want to spend all the time needed for a fresh install.
