I can not set nfs4leasetime value less than 10 seconds.
there is a verification in __write_leasetime(). (lease < 10 || lease > 3600)
I am going to change this to ~2 second (to make NFS HA failover happen
in less than 10 seconds with HeartBeat).
Any reason why is this checked for 10 (i.e. lease < 10) ... ?
static ssize_t __write_leasetime(struct file *file, char *buf, size_t size)
{
/* if size > 10 seconds, call
* nfs4_reset_lease() then write out the new lease (seconds) as reply
*/
char *mesg = buf;
int rv, lease;
if (size > 0) {
if (nfsd_serv)
return -EBUSY;
rv = get_int(&mesg, &lease);
if (rv)
return rv;
if (lease < 10 || lease > 3600)
return -EINVAL;
nfs4_reset_lease(lease);
}
return scnprintf(buf, SIMPLE_TRANSACTION_LIMIT, "%ld\n",
nfs4_lease_time());
}
