Trying to get OST running in embedded environment:
mkfs.lustre & tunefs.lustre commands (seem to) work.
MDT/MGS up & running on 'normal' x86 platform - different server.
mount command fails - looks like parameters aren't passed to lmd_parse.
An added printk to display options passed to routine showed a NULL
string was being passed to the routine.
I corrected an error yesterday in mkfs_lustre.c return value of
getopt_long call was being assigned to a char var not long. Caused the
gcc cross compiler to optimize out the termination condition since a
char can never equal EOF (-1).
output below varied on seems to indicate options are position sensitive.
console output follows - my printk debug is included - option string
passed to lmd_parse is enclosed by >> <<:
I'll start going thru the calls above lmd_parse.
Ideas are appreciated.
