[OmniOS-discuss] otherwise stable system sudden crashing

[Dan McDonald]

I took a look at your dumps.

Both vmdump.0 and vmdump1 have the same stack:

vpanic()

zfs_acl_ids_create+0x4d2(ffffff0799931ab0, 2, ffffff00194bdcb0, ffffff055d97ddb0

Do you know exactly what you did to reproduce this panic?




After r151018 was released, there were at least FOUR changes near the code that's panicking on you:

6762 POSIX write should imply DELETE_CHILD on directories - and some additional considerations
6763 aclinherit=restricted masks inherited permissions by group perms (groupmask)
6764 zfs issues with inheritance flags during chmod(2) with aclmode=passthrough
6765 zfs_zaccess_delete() comments do not accurately reflect delete permissions for ACLs

Unfortunately, none of those bugs mention a kernel panic.


Are you willing to try OmniOS bloody (with DEBUG enabled) on a be on your system?  Or at least are you willing to run a DEBUG kernel on your r151018 environment?  Either one of these would be most helpful.

Thanks,
Dan
