[DragonFlyBSD - Bug #3056] HAMMER2 corruption - nonexistent files

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #3056 has been updated by dillon.


I hit the cluster_write() crash too, and it should now be fixed in master.  It turned out to be a bug in devfs that only hammer2 tickles due to the way hammer2 uses cluster_write().

Also fixed a number of other issues this morning (see the git logs), including a corruption bug that can triggered by a crash or panic.

After one crash (like a week ago) I got one dir damaged:

> find . | wc -l
     144

> find . -type f |& wc -l
     142

> find .
…
./standard/module.time.9.cfg
./standard/module.notification.3.cfg
./standard/e_bindings.6.cfg
./standard/module.gadman.3.cfg
./standard/systray.5.cfg
./standard/module.tasks.5.cfg
./standard/e_bryces.5.cfg
…

> find . -type f
…
find: ./standard/module.conf.9.cfg: No such file or directory
find: ./standard/module.music_control.7.cfg: No such file or directory
find: ./standard/module.everything-apps.3.cfg: No such file or directory
find: ./standard/module.ibar.7.cfg: No such file or directory
find: ./standard/module.syscon.6.cfg: No such file or directory
…

No messages on system console even with vfs.hammer2.debug=1. Not fixed with cleanup/blukfree. Current kernel: 2e8a93d8402e.
