I have an i386 machine I use as a server for a media system. I access the storage through samba, and I manage some of the disk space with vnd. One particular vnd backed filesystem is read-only. That is, the vnd disk is configured with vnconfig -r, and it's mounted in a readwrite samba share.
I never had a problem until I browsed it with my new Mac, and it panics. I can consistenly recreate the panic. The machine doesn't write a dump file to /var/crash for whatever reason, but I copied a few of the tracebacks: Here's one (hand copied, sorry for typos): Stopped in pid 591.1 smbd at netbsd:breakpoint+0x4: popl %ebp breakpoint panic ffs_blkfree ffs_realloccg ffs_balloc ufs_gop_alloc ufs_balloc_range ffs_write VOP_WRITE vn_write dofilewrite sys_pwrite syscall Here's another: breakpoint panic ffs_blkfree ffs_truncate ufs_setattr VOP_SETATTR sys_ftruncate syscall (I might be able to copy all details or run some ddb commands if needed. It would be better if I had a dump file.) I guess write or setattr shouldn't be allowed in this case, and there should be some error passed back. This is the machine: $ uname -a NetBSD machine 5.2_STABLE NetBSD 5.2_STABLE (MACHINE.JUL25_2013) #0: Thu Jul 25 22:19:26 MST 2013 root@machine :/usr/obj-i386-5/sys/arch/i386/compile/MACHINE.JU L25_2013 i386 I just built this kernel a few days ago. I searched open bugs and I don't see anything similar. Any ideas? Andy
