Transport endpoint is not connected

[bcnx]

Hi,

running the latest RioFS on CentOS 7.
We can successfully mount a bucket, but as soon as we do a rsync to the mount from a different server, we get the "Transport endpoint is not connected" error message and the mount is unresponsive. We need to unmount and mount again for the mount to be active again, but as soon as we launch a new rsync, the same issue occurs.

At the same time we cannot delete files with for instance the "&" symbol in it's name. Maybe this is related, in such a way that the mount crashes on these funny filenames?

Thanks for looking into this!

This is in the dmesg output:

RioFS seems to have crashed.

Hello,

could you please help me to debug RioFS crash:

1. could you please run RioFS with gdb to get crash backtrace:
   gdb -ex "bt full" --batch -c core --args riofs [your arguments here] > /tmp/riofs_bt.txt

just make sure that after "--args" you provide your usual command line arguments as if you run riofs. After you start RioFS try to reproduce the crash. If RioFS crashes please send me /tmp/riofs_bt.txt file (but please be aware that it could contain some sensitive data, such as file names. So it would be great if you run RioFS for some test bucket).

2. could you please provide me with detailed information how you managed to crash RioFS, which actions were performed just before it crashed? any additional information would be really helpful! Thank you!

Hi,

 
As we were rather in a hurry to get things sorted, we decided to go with S3QL. This seems to be a better choice for our purposes, as it is fully compliant with POSIX. 

 
 
Met Vriendelijke Groet,
Kind Regards,
