Sorry for inconvenience.
To get better cleanerd logs, change log_priority level specified in
/etc/nilfs_cleanerd.conf as follows:
This will make the cleanerd write debug information in syslog.
Note that a HUP signal must be sent to the cleanerd or doing
umount/mount the nilfs partition is required to reflect the change.
Then, if nilfs2 seems to hang during GC, please get a stack dump by
sending the following system request from an active terminal or
# echo t > /proc/sysrq-trigger
This will dump stack information of every kernel thread. The stack
information that contains `nilfs' keywords would give the hint about
which function causes the hang problem.
