:Hi.
:Caught this panic on latest DragonFly_RELEASE_2_0 (minus the fix to
:vfs_subr.c, but the machine has less than 2G RAM), when I tried to
:destroy a PFS slave on HAMMER filesystem. The PFS hasn't been actively
:used, only to try mirror-copy of another PFS, which is used as /usr/obj.
:The panic also occurs when I try to reblock this PFS, but no problem
:to upgrade to a PFS master. I don't have a problem reblocking or pruning
:other PFS's or HAMMER filesystem containing them.
:...
:The kernel dump has been uploaded as ~y0netan1/crash/{kernel,vmcore}.13
:on my leaf account.
:
:Cheers.
This looks fairly serious. The big-block has been marked free but the
rollback code is trying to delete a data element that still
references it.
I am going to need some additional information from you. Please sync
your filesystem and then do the following:
hammer -f <device> blockmap > textfile
hammer -f <device> -vvv show >> textfile
And gzip and upload that to leaf.
