Hi Travis! Thank you very much for pinpointing these issues to us. We'll think of implementing a "mfsbind=IP" option which would allow connecting to a specified IP which consequently would cause the use of an adequate interface. At this moment this functionality is not available.

Subject: [Moosefs-users] have mfsmount 'use' a specified network interface? Im running moosefs on my notebook, the latest in the git repository MFS version 1.6.11 FUSE library version: 2.7.4 I have set up a 'tun' interface and given that an ip address of 10.0.0.1, and have the msfmaster and chunkserver attach to this. The motivation being I have both wireless and wired network interfaces on the notebook and don't want the service to have any kind of dependency on on which ever one is currently active, but also, because I move between different places, different IP addresses on the LAN too. the mfsmaster and one mfschunkserver process run on this 10.0.0.1 address and then the mfsmount command in use is mfsmount -H 10.0.0.1 /mnt/mfs But it appears the mfsmount is choosing one of the other interfaces to connect 'from', such as eth0, or wlan0, and connecting from (what ever IP address is on that LAN at the time). I noticed this as I had to enter the 192.168.x.x address into the mfsexports.cfg in addition to the 10.0.0.x one, which I added to allow it to mount for now. The main issue is usually after suspending the notebook and coming back online (in a different network) the mfs mount seems to get lost ls /mnt/mfs ls: cannot access /mnt/mfs: Input/output error So is there a way to make the mfsmount work on a specified interface that it attempts to use when connecting to its master and chunk servers?

My motivation is to have the services on the host and to have the mfsmount client inside one or more virtual machines, that also work on this tun interface, so as to create a shared file system for all the virtual machines. and in my road warrior setup the everything on one host works well. But I wonder if it could come up in complex clusters or other multi-homed machines where a high performance network and a low performance management network were both available and the networks could some how route between each other, that could cause the data traffic from the mount to end up going over the lower performance management network or something . ---------------------------------------------------------------------------- -- Throughout its 18-year history, RSA Conference consistently attracts the world's best and brightest in the field, creating opportunities for Conference attendees to learn about information security's most important issues through interactions with peers, luminaries and emerging and established companies. http://p.sf.net/sfu/rsaconf-dev2dev _______________________________________________ moosefs-users mailing list moo...@li... https://lists.sourceforge.net/lists/listinfo/moosefs-users |

Be advised: if you have a large chunk on 1.5 and migrate it to 1.6 it might rearrange the files in subfolders. For 280G it took about 1h. Thankfully it was ok even if i stopped it a few times :) Use strace to check on progress. -- Eduard Steve wrote: > I agree its totally amazing. > > 1. 1.6 running fine for me > > 2.

Hi!
Thank you very much for your interest in MooseFS!
1. Yes, version 1.6.11 is stable and is widely used in several companies (at our company we have ca. 1 petabyte of data).
2. Please refer to the UPGRADE file which is in a root folder of the .tar.gz It is important to make the upgrade in a right order.
Kind regards
Michal Borychowski

Hi! Yes, you can safely remove this line. It is an artefact from an even earlier MooseFS version. The problem you described exists also on reiserfs and jfs, it doesn't affect ext2/ext3/ext4.

Subject: [Moosefs-users] branch 1.5.x on XFS - chunk loses files on restart Hi. I'm using 1.5.12 and I want to put the chunk on XFS. It seems that the chunk disregards all files after restart. We tracked the issue to #define HAVE_STRUCT_DIRENT_D_TYPE 1 and removed that line. Afterwards it seems to work ok. Considering that an upgrade to 1.6 is not possible right now could you please advice on the possible issues coming from removing the line above in conf?
