this is when I try and work with a file created with

dd if=/dev/zero of=100M count=1 bs=100M

the FreeBSD side crashed while it was being created.

I deleted the file from the AFR, however the 100M file still exists on the FreeBSD server. If I try and delete the file off of the FreeBSD server via gluster, it crashes.

I can delete the 100M file from the filesystem directly to get gluster working again. Trying to make the 100M file again afterwards will crash the server again.

this is also occurring with "touch"

after starting all servers without any xlators at all, the crash continued to happen.

I stopped using debug on the FreeBSD server and saw the following errors:

2008-12-29 15:19:25 E [server-protocol.c:2431:server_stub_resume] server: OPEN (/me) on nas2 returning error: -1 (2)
2008-12-29 15:19:25 E [server-protocol.c:2533:server_stub_resume] server: XATTROP (/me) on nas2 returning error: -1 (2)
2008-12-29 15:20:07 E [server-protocol.c:2567:server_stub_resume] server: UNLINK (/me) on nas2 returning error: -1 (2)

this was after an attempted "touch me" and "rm me".

after this, whatever was out of sync was in sync and the servers acted as normal again.
