Hi
I want add some code in dht_create before doing create in hashed_subvol.
I want write something in all subvols with setxattr operation.
My problem is that when I want get lock (write lock) on subvols, I get error:
pending frames:
frame : type(1) op(CREATE)
frame : type(1) op(CREATE)
frame : type(0) op(0)
patchset: git://git.gluster.com/glusterfs.git
signal received: 11
time of crash:
2017-04-21 06:38:23
configuration details:
argp 1
backtrace 1
dlfcn 1
.
.
.
But if I just get lock on one subvol, the step of getting locks do correctly.
I dont know the problem! Are subvols that get from layout from a file parent inode fake?? (from dht_get_layout function)
If I get these locks from a directory for example in a setxattr operation, there is no problem.
The function of lock is dht_blocking_inodelk in dht_commom.c and the operation
STACK_WIND_COOKIE (frame, dht_blocking_inodelk_cbk,
(void *) (long) i,
local->lock.locks[i]->xl,
local->lock.locks[i]->xl->fops->inodelk,
local->lock.locks[i]->domain,
&local->lock.locks[i]->loc, F_SETLKW, &flock, NULL);
(in dht_blocking_inodelk_rec function )raise error.
