Hi,
It seems my NILFS is not garbage collected. The other day I was not able
to boot up my NixOS due to a full disk. I booted on a USB stick and ran
nilfs-clean which freed about 20 Gbytes. I suppose there should always
be a process nilfs_cleanerd running on a system in order to clean up old
check points. I have actually not read on the NILFS web site that
nilfs_cleanerd should be running normally, but maybe I have missed this.
Should it not be running normally?
When I am running nilfs-clean on my device, I get:
'No cleaner found on /dev/dm-0.'
mount | grep nilfs gives:
/dev/mapper/cryptroot on / type nilfs2 (rw,relatime)
/dev/mapper/cryptroot on /nix/store type nilfs2 (ro,relatime)
nilfs-clean -V gives:
nilfs-clean version 2.2.3
I am only able to run nilfs_cleanerd after setting LD_LIBRARY_PATH to
/nix/store/*-nilfs-utils-2.2.3/lib
nilfs_cleanerd /dev/mapper/cryptroot
NILFS_CLEANERD_PID=24468
It seems however like the process terminates since there does not seem
to exist any process when running 'ps aux | grep nilfs'
When trying 'sudo mount -t nilfs2 -o remount,pp=1 /dev/mapper/cryptroot
/', I get:
/nix/store/y0ldq0j9qpax23d6g5iww7nz17xgx32q-nilfs-utils-2.2.3/sbin/nilfs_cleanerd:
error while loading shared libraries: libnilfs.so.0: cannot open shared
object file: No such file or directory
mount.nilfs2: Warning: cannot get pid of cleanerd
mount.nilfs2: cannot modify /etc/mtab.
Please remount the partition with -f option after making /etc/mtab
writable.
I am running NixOS 16.03
'uname -r' gives:
4.4.14
Any ideas?
Thanks in advance.
Kind regards,
Mikael Andersson

Hi again,
I am now able to run nilfs_cleanerd after running it as root... :) When
I am running it with sudo I get below, although I set LD_LIBRARY_PATH
first:
nilfs_cleanerd: error while loading shared libraries: libnilfs.so.0:
cannot open shared object file: No such file or directory
Maybe sudo starts a new shell and loses the LD_LIBRARY_PATH variable?
I think it is rather strange and confusing that nilfs_cleanerd says
'NILFS_CLEANERD_PID=25215' without being able to start a process
properly. Is that perhaps a bug?
My problem is still:
[root@nixos:/home/mikael]# nilfs_cleanerd /dev/mapper/cryptroot
nilfs_cleanerd: error while loading shared libraries: libnilfs.so.0:
cannot open shared object file: No such file or directory
If I set LD_LIBRARY_PATH, I am however able to start nilfs_cleanerd as
root.
Any ideas?
Kind regards,
Mikael Andersson

I don't know the detail of NixOS, but the reason why nilfs_cleanerd
aborted looks to be in this environmental issue.
> shared object file: No such file or directory
> mount.nilfs2: Warning: cannot get pid of cleanerd
This message indicates mount.nilfs2 failed to receive pid
from nilfs_cleanerd. It looks like nilfs_cleanerd aborted before
handing over the pid completes.

Is /etc/mtab a symlink to /proc/self/mounts ?
If so, this mount.nilfs2 (NixOS distro package ?) looks to be
wrongly built.
There are two version with regards to mount.nilfs2, one uses /etc/mtab
and another uses libmount. The latter doesn't rewrite /etc/mtab.
The latter version of mount.nilfs2 can be built with "--with-libmount"
configure option from the nilfs-utils source package.
$ ./configure --with-libmount
$ make

Seems that libnilfs.so is loaded when its function is used first time.
nilfs_cleanerd first tries to deliver PID to the parent process and
then call a function of libnilfs. So, this order looks to be natural.

Try ldd to investigate library dependency.
$ ldd /sbin/nilfs_cleanerd
If libnilfs.so is "not found", add the library path
where libnilfs.so exists, to /etc/ld.so.conf or /etc/ld.so.conf.d/*.conf.
And, then run ldconfig.
Usually we don't have to care this kind of task. It looks like there
is a problem in the NixOS distro package or your system environment.
