Hello! Yesterday I have made the transition from xfs to nilfs on the /home partition of my notebook, and since then, with the same usage as before,i have experienced deadlocks 3 times.
The situations were the following:
using gimp to cut a picture
browsing web with epiphany browser
epiphany again
rtorrent was running in the background.
What I experienced:
suddenly hdd activity starts. possibly because of swapping (i have 512m ram,
and only gimp/epiphany are likely to eat much ram, i use wmaker and console
based programs mostly)
i can't kill gimp/epi, i can log in at other VT-s with root, but not with user.
thing that touch /home (even ls!), sync simply get stuck, and even kill -9
can't kill the stuck program. therefore i must assume it got stuck in some
syscall, in kernel mode or something similiar, possibly in the nilfs2 module. I
must assume this, as the hangs seemed to be in connection with /home.
i couldn't restart the computer cleanly,had to power-cycle it, and after
restart the system got alive as expected (i noticed there is no fsck util.
isn't fsck needed? is a roll forward from last cp done at mount? ) The garbage
collector couldn't have donethis,, in theory, as i ordered it to have a 3 day
long protection interval.
my GC put the following message to the logs:
Jan 16 01:19:00 vosztok nilfs_cleanerd[29597]: start

Jan 16 17:54:35 vosztok nilfs_cleanerd[9661]: open
/var/run/nilfs_cleanerd-dm-1.pid
And the module gave these messages:
Jan 16 17:54:34 vosztok kernel: NILFS warning (device dm-1): nilfs_sync_super:
barrier-based sync failed. disabling barriers
Jan 16 17:54:34 vosztok nilfs_cleanerd[9661]: start
Jan 16 17:54:35 vosztok nilfs_cleanerd[9661]: open
/var/run/nilfs_cleanerd-dm-1.pid
Please help me, (as tough i love nilfs even after this short interval of use,
this quite reduces the user experience :) ) and tell me how, and what
information should I provide to help you fix the problem.
Thanks in advance:
