Hello,
I am debugging a basic translator that was created based on the rot-13 example, but I'd like to gather more info on how to procede at the example below.
So, the volfile I'm using is very basic, with two directories(bricks) configured as posix volumes and my translator using both as subvolumes.
Now suppose I want to write the same file on both subvolumes (like an echo "abc" > /mnt/glustermount/test.txt).
I tried to loop through the this->children list at the writev function, calling the writev of each subvolume (as copied below) instead of the FIRST_CHILD macro.
At the 1st subvolume it was ok, but at the second one I got a segmentation fault when calling the STACK_WIND complaining about pthread_spin_lock.
What other kind of structure/control I'd need to build to replicate the content over all the subvolumes I have?
What I want at first is to know how I can control the write over different subvolumes, so any hint here is welcome.
190 xlator_list_t *list = this->children ;
191 while (list) {
192 STACK_WIND (frame, gbfs_writev_cbk, list->xlator,
193 list->xlator->fops->writev, fd, vector, count, off,
194 flags, iobref, xdata);
195 list=list->next;
196 }
Thanks,
Gustavo Brand
