Hi list,
I will try to sort information from few messages together here.
Attached strace output from my "nilfs_cleanerd" for rootfs. The script
is in /etc/local.d (again, Gentoo Linux) and it looks like this (removed
commented parts and empty lines):
CONFILE="/etc/nilfs_cleanerd_rootfs.conf"
TARGETDISK="/dev/disk/by-uuid/1aa9e6fb-cf7d-45bd-bbfb-08110a8840b7"
/sbin/nilfs_cleanerd -c "${CONFILE}" "${TARGETDISK}"
And here's the mentioned nilfs_cleanerd_rootfs.conf:
protection_period 3600
min_clean_segments 13%
max_clean_segments 25%
clean_check_interval 10
selection_policy timestamp # timestamp in ascend order
nsegments_per_clean 2
mc_nsegments_per_clean 4
cleaning_interval 5
mc_cleaning_interval 1
retry_interval 60
use_mmap

That's right, lscp -a gives some more output:
maszyn ~ # lscp -a | wc -l
1428
Running nilfs_cleanerd with more verbose output (log_priority debug)
gives me this:
Jul 10 09:45:26 [nilfs_cleanerd] start
Jul 10 09:45:26 [nilfs_cleanerd] cannot open nilfs on /dev/sda2: No such
file or directory
Jul 10 09:45:26 [nilfs_cleanerd] cannot create cleanerd on /dev/sda2: No
such file or directory
Jul 10 09:45:26 [nilfs_cleanerd] shutdown
