[zfs-discuss] Re: ZFS over a layered driver interface
Thanks Eric and Manoj.
Here''s what ldi_get_size() returns:
bash-3.00# dtrace -n ''fbt::ldi_get_size:return{trace(arg1);}''
-c ''zpool create adsl-pool /dev/layerzfsminor1'' dtrace:
description ''fbt::ldi_get_size:return'' matched 1 probe
cannot create ''adsl-pool'': invalid argument for this pool
operation
dtrace: pid 2582 has exited
CPU ID FUNCTION:NAME
0 20927 ldi_get_size:return 4294967295
This is strange because I looked at the code for ldi_get_size() and the only
possible return values in the code are DDI_SUCCESS (0) and DDI_FAILURE(-1).
Looks like what I''m looking at either isn''t the return value,
or some bad address is being reached. Any hints?
Thanks,
Swetha.

Try ''trace((int)arg1);'' -- 4294967295 is the unsigned representation of -1.
