Hi all, So, this is what I'm observing. $ sudo nfsiostat Traceback (most recent call last): File " in="" line="" module="" nfsiostat="" sbin="" usr=""> iostat_command(prog) File "/usr/sbin/nfsiostat", line 587, in iostat_command devices = list_nfs_mounts(origdevices, mountstats) File "/usr/sbin/nfsiostat", line 490, in list_nfs_mounts stats.parse_stats(descr) File "/usr/sbin/nfsiostat", line 179, in parse_stats self.__parse_rpc_line(words) File "/usr/sbin/nfsiostat", line 163, in __parse_rpc_line self.__rpc_data[op] = [long(word) for word in words[1:]] ValueError: invalid literal for long() with base 10: 'device' This happens because it's unexpected for nfsiostat to find line "no device mounted on /sys/kernel/debug with fstype debugfs" in /proc/self/mountstats. http://pb.abhijeetr.com/UREA For now, I added if line.startswith("no device mounted"): continue to fix the issue in parse_stats_file function. http://pb.abhijeetr.com/HUXO Please ask if any more info is required. What's the best way to handle it so that it can be added to upstream code? -- Regards, Abhijeet Rastogi (shadyabhi) http://blog.abhijeetr.com -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
