Hi,
The new marker xlator uses syncop framework to update quota-size in the
background, it uses one synctask per write FOP.
If there are 100 parallel writes with all different inodes but on the
same directory '/dir', there will be ~100 txn waiting in queue to
acquire a lock on on its parent i.e '/dir'.
Each of this txn uses a syntack and each synctask allocates stack size
of 2M (default size), so total 0f 200M usage. This usage can increase
depending on the load.
I am think of of using the stacksize for synctask to 256k, will this mem
be sufficient as we perform very limited operations within a synctask in
marker updation?
Please provide suggestions on solving this problem?
Thanks,
Vijay
