Re: [Moosefs-users] Connection timed out at mfsmount on boot

Hi Stas!

 

What platform do you use? The solution with /etc/fstab works only on Linux
platforms (tested on Debian). On other platforms you need to prepare a
script in /usr/local/etc/rc.d which will run mfsmount with needed options.

 

And on Linux you need _netdev option, as written on
http://www.moosefs.org/reference-guide.html in "Mounting the File System"
section. 

 

 

Kind regards

Michal

Subject: Connection timed out at mfsmount on boot

 

Hi.

We have the mfsmount set in fstab, but noticed it never properly works on
boot.

When the system comes up, it just logs:
Jan 15 06:55:51 ovsa1 mfsmount[6926]: file: 63934, index: 0, chunk:
24383640, version: 1 - writeworker: connection with (C0A80214:9422) was

Jan 15 06:56:48 ovsa1 mfsmount[6926]: writeworker: write error: 26


Also, the mfsmount never retries to connect after these errors.

Any idea how to resolve this, perhaps by increasing the timeout, or making
mfsmount reconnect until it succeeds?

Thanks in advance.
