HiI 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: 11time of crash:2017-04-21 06:38:23configuration details:argp 1backtrace 1dlfcn 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 operationSTACK_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.
Mostly because its a file and inode context is not present on all the subvols?
