Hallo,
Here is an interesting disaster with nilfs2. Lightening went down the
chimney on the other side of the wall. Computer was off, but plugged in.
Motherboard died.

So I now try to fix partitions. at the moment it is /var. /home will come
later.

Here is the problem:
/var data is readable but the cleanerd has become confused after the
disaster and has filled up the partition

partition size 5.8 Gig, data size 2.56 Gig, but usage is now 100%
Normal mounting:
cleanerd cannot be stopped anymore, neither with TERM or KILL signals.

lscp shows only cleaner checkpoints now.

When mounting without the cleanerd running there are no dmesg's of interest
on mounting or on execution of any command

To rescue the partition do I copy the data to another disk and reformat? Or
is there a simpler solution?

Best Regard,

Jan de Kruyf.
