Yesterday I have made the transition from xfs to nilfs on the /home partiti= on of my notebook, and since then, with the same usage as before,i have exp= erienced 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 conso= le based programs mostly) i can't kill gimp/epi, i can log in at other VT-s with root, but not with u= ser. thing that touch /home (even ls!), sync simply get stuck, and even kil= l -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 /h= ome. i couldn't restart the computer cleanly,had to power-cycle it, and after re= start the system got alive as expected (i noticed there is no fsck util. is= n't fsck needed? is a roll forward from last cp done at mount? ) The garbag= e 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 01:19:00 vosztok nilfs_cleanerd[29597]: cannot create cleanerd on /d= ev/vosztok_vg/home Jan 16 01:19:00 vosztok nilfs_cleanerd[29597]: shutdown Jan 16 17:51:54 vosztok nilfs_cleanerd[4254]: close /var/run/nilfs_cleanerd= -dm-1.pid Jan 16 17:51:54 vosztok nilfs_cleanerd[4254]: unlink /var/run/nilfs_cleaner= d-dm-1.pid Jan 16 17:51:54 vosztok nilfs_cleanerd[4254]: shutdown 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 And the module gave these messages: Jan 16 17:54:34 vosztok kernel: NILFS warning (device dm-1): nilfs_sync_sup= er: 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 us= e, this quite reduces the user experience :) ) and tell me how, and what in= formation should I provide to help you fix the problem.
