Hello Stephen, we are very happy that you are using MooseFS :) MooseFS doesn't have hard-coded client number limits. We have installations with about 300 clients (mounts) working and probably handling more than 300 mounts is not a problem at all for MooseFS :) If you have any other questions, please don't hesitate to contact us. -- Best regards, Piotr Robert Konopelko *MooseFS Technical Support Engineer *| moosefs.com[1] hi the moosefs team I am stephen.

Hello, 1.6.15 is a *very* old and not supported version of MooseFS. I recommend upgrade your whole instance to the MooseFS 2.0.48 CE, because in 2.0.x branch a lot of improvements and bug fixes has been made. Please keep in mind, that supported way to upgrade your instance is: *Your version* -> *1.6.27-5* ->* 2.0.x CE*, so first of all you need to upgrade to 1.6.27-5 and then to 2.0.48 CE. Please remember to back up your metadata, changelogs and configuration files before starting an upgrade. The whole upgrade process is described in *MooseFS Upgrade Guide* (you can download it from the URL below), so please refer to this document. I also very recommend reading *MooseFS 2.0 Step-by-Step Installation Guide*. You can obtain documentation at http://moosefs.com/documentation.html[1]. Also, at http://get.moosefs.com[2] you can find useful information about installing MooseFS from packages, so now you don't need to compile MooseFS yourself (but you still can if you want, because sources of MooseFS 2.0.x CE are available). In case of any questions, please don't hesitate to contact our Technical Support Department at dw...@mo...[3] or mailing list at moo...@li...[4]. -- Best regards, Piotr Robert Konopelko *MooseFS Technical Support Engineer *| moosefs.com[5] hello Piotr Robert Konopelko Thanks very much for your reply.

Hello again, all versions from 1.6.x branch are no longer supported. Upgrading MooseFS is a *safe* operation, because your data is not even touched. *The most important thing* during the upgrade is to make it even more safer: Your *metadata* is stored on master server. When you stop the master server, it dumps the metadata from RAM to file named *metadata.mfs* So the most important thing is to *make a backup* of this file. We upgraded a lot of instances, even 1.0 PiB and bigger and *every time* upgrade was successful, so you don't need to be afraid. Please read carefully this document: http://moosefs.com/Content/Downloads/moosefs-upgrade.pdf[1] and if you will have any questions after reading this guide, please ask me :) We *really* recommend upgrading MooseFS. -- Best regards, Piotr Robert Konopelko *MooseFS Technical Support Engineer *| moosefs.com[2] Yes I know 1.6.15 is old.But my data is vesy big and very important.

Hello, 1.6.15 is a *very* old and not supported version of MooseFS. I recommend upgrade your whole instance to the MooseFS 2.0.48 CE, because in 2.0.x branch a lot of improvements and bug fixes has been made. Please keep in mind, that supported way to upgrade your instance is: *Your version* -> *1.6.27-5* ->* 2.0.x CE*, so first of all you need to upgrade to 1.6.27-5 and then to 2.0.48 CE. Please remember to back up your metadata, changelogs and configuration files before starting an upgrade. The whole upgrade process is described in *MooseFS Upgrade Guide* (you can download it from the URL below), so please refer to this document. I also very recommend reading *MooseFS 2.0 Step-by-Step Installation Guide*. You can obtain documentation at http://moosefs.com/documentation.html[3]. Also, at http://get.moosefs.com[4] you can find useful information about installing MooseFS from packages, so now you don't need to compile MooseFS yourself (but you still can if you want, because sources of MooseFS 2.0.x CE are available). In case of any questions, please don't hesitate to contact our Technical Support Department at dw...@mo...[5] or mailing list at moo...@li...[6]. -- Best regards, Piotr Robert Konopelko *MooseFS Technical Support Engineer *| moosefs.com[1] hello Piotr Robert Konopelko Thanks very much for your reply.

Hello Stephen, we are very happy that you are using MooseFS :) MooseFS doesn't have hard-coded client number limits. We have installations with about 300 clients (mounts) working and probably handling more than 300 mounts is not a problem at all for MooseFS :) If you have any other questions, please don't hesitate to contact us. -- Best regards, Piotr Robert Konopelko *MooseFS Technical Support Engineer *| _moosefs.com_ hi the moosefs team I am stephen. I am from china. Now I want to know what is the client number that the moosefs can support? please tell me ,tinaks! -------- [1] http://moosefs.com [2] http://moosefs.com/Content/Downloads/moosefs-upgrade.pdf [3] http://moosefs.com/documentation.html [4] http://get.moosefs.com [5] mailto:dw...@mo...
