My workstation got screwed up today, I cannot delete any file, nor write
anything to the root filesystem, even though "mount" says there are a
few GB free... any operation, including btrfs balance, defragment etc or
"no space left on device" :-(((
I think I figured out what's going on, for some reason snapper wrote
snapshots to the root filesystem in a directory called ".snapshots"
those apparently are filling this small ssd drive.. attempting to delete
subvolumes results in two different kind of mess ;)
- If I attempt to rm -rf .snapshots it says that it is read only fs
-If I attempt to delete using either snapper or btrfs subvolume, the
kernel oopses and the the machine freezes up, REISUB has to be used to
make it run again...
Unfortunaly my camera is also broken and I cannot take a photo of the
aby hints appreciated,,,
I've saw exactly the same situation in a vm
/ being full 360Mb free during a zypper dup
Was hardtime to understand what's happening until I catch snapper eating 9.8Go of
(I think a ratio of a maximum of 50% should be never exceeded for snapshots)
There is something really wrong with this stuff..
- All monitoring programs report that there is space available.
- No popup, no warning whatsoever that the filesystem X is becoming full
(probably related to the previous one)
- Subtle random "no space left on device".. usually "fixed" by running
btrfs filesystem balance ... or something absurd like:
first time : osc build --clean --> delay --> rpm complains about the
db..then no space left on device, no packages installed.
second time: osc build --clean --> setup packages but stops at the few
third time --> rm -rf /path/to/the/package/build/root
osc build --> package builds correctly, no errors, system normal ..you
can write anything else to the FS.. WTF !!!
osc build --> some *other* app, like the music player or the browser
