Another simple test in code would be to check whether inode->fd_list is empty as fd_list represents list of all fds opened on that inode.

Hi Ram,

Do you want to check this from within a translator? If so, you can look for GLUSTERFS_OPEN_FD_COUNT in xlators like dht, afr, ec etc. where they check for open file descriptors in various FOPs.

Vijay

Hi,
       Is it possible to find out within a cluster if a file is currently open by any of the clients/self-heal daemon or any other daemon’s within a cluster. Please point to the sample code in any of the Xlator which does such a check.

Thanks and Regards,
Ram
